Abstract
The time interval between HIV-1 infection and AIDS development is not the same in all patients and depends largely on the genetic background of the individual. Polymorphisms in the TREX1 gene, the main enzyme in the clearance of cytosolic DNA, affect type 1 interferon-mediated inflammatory response in HIV-1 infection. We aimed to study the role of a single nucleotide polymorphism (rs3135941) of the TREX1 gene and the rate of disease progression in patients infected with HIV-1. A total of 190 HIV-1 infected patients were recruited. Patients' demographic and laboratory data including CD4 counts, viral load, and antiretroviral therapy (ART) were collected. The genotype of rs3135941 was determined by a PCR-SSP method. The rate of progression to AIDS was calculated with Kaplan-Meier survival analysis using Stata software. The patients were divided into rapid and slow progressors based on time interval of CD4 drop below 350/µl. Kaplan-Meier analysis revealed an accelerated disease progression in patients with TC and CC genotypes (HR = 1.49, 95% CI = 1.01-2.17). The mean values of the first 5-year CD4 counts were significantly different in patients who had CC and TC genotypes compared to the TT group (p = 0.036). The result of this study emphasizes the importance of TREX1 polymorphism in HIV-1 progression. These data warrant further investigation into the role of other polymorphisms of TREX1.

Silva MJA, Marinho RL, dos Santos PAS, dos Santos CS, Ribeiro LR, Rodrigues YC, Lima KVB, Lima LNGC. The Association between CCL5/RANTES SNPs and Susceptibility to HIV-1 Infection: A Meta-Analysis. Viruses 2023; 15:1958. [PMID: 37766364 PMCID: PMC10535444 DOI: 10.3390/v15091958] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2023] [Revised: 09/10/2023] [Accepted: 09/11/2023] [Indexed: 09/29/2023] Open
Abstract
Genetic polymorphisms in genes that encode natural ligands of CCR5 (the main human HIV coreceptor), such as CCL5/RANTES, can alter the levels of secretion of these peptides. This article sought to review the relationship between single nucleotide polymorphisms (SNPs) of CCL5/RANTES and HIV-1 disease susceptibility. A meta-analysis was conducted through 17 articles found from January 1999 to December 2022 in the PUBMED, Science Direct, Medline, and SciELO databases. A total of three SNPs were identified and investigated under their dominant genotypic model and through a fixed-effects model. In terms of the SNP rs2107538 (G > A), in Africa and Asia, it has a protective role (OR = 0.56; 95% CI = 0.41-0.76; p = 0.0002, and OR = 0.88; 95% CI = 0.76-1.02; p = 0.08, respectively). In terms of the SNP rs2280788 (C > G), in Europe and America, it shows a higher risk role (OR = 1.92; 95% CI = 1.06-3.47; p = 0.03, and OR = 0.94; 95% CI = 0.94-1.11; p = 0.04, respectively), but in the population of Asia, with its mutant allele, it has a protective role (OR = 0.76; 95% CI = 0.63-0.93; p = 0.007). In terms of the SNP rs2280789 (T > C), no significant associations were found. Both SNPs rs2107538 and rs2280788 have a positive transcriptional effect on the RANTES/CCL5 gene, while SNP rs2280789 causes a decrease in gene expression levels. This study suggests that there is an association between the increased expression of CCL5/RANTES and a lower risk of AIDS. Therefore, further studies are needed to arrive at a definitive conclusion, and these results may help establish scientific bases for effective HIV/AIDS control strategies.

Abstract
AIM Due to conflicting data from relevant studies, evidence for chemokine alterations in the pathophysiology of schizophrenia (Scz) remains inconclusive. Thus, we aimed to investigate the impact of rs2107538, rs2280788, and rs2280789 polymorphisms in CCL5 gene, as well as rs333 within CCR5 gene and the development of Scz in a Tunisian cohort. METHODS We performed a case-control study composed of 200 patients and 200 controls using RFLP-PCR. RESULTS Among the analyzed polymorphisms, only rs2107538 imparted protection against Scz and more specifically to male sex. This protective effect remained valid for the undifferentiated form. Moreover, this SNP had an impact on patients' symptomatology. When focusing on haplotypes, we noticed that the rs2107538-rs2280788-rs2280789 ACT genetic combination, with only one mutated allele rs2107538A, displayed reduced frequency in both Scz (as a whole group) and undifferentiated subtype. The haplotype distribution profile implies that the A allele at rs2107538 could induce a protective effect by increasing RANTES production. CONCLUSION Additional independent analyses are required to corroborate these findings and elucidate the functional implications of the discovered preventing genotypes and haplotypes in Scz.

Abstract
SARS-CoV-2 (Severe Acute Respiratory Syndrome coronavirus-2) is the third coronavirus to emerge as a cause of severe and frequently fatal pneumonia epidemics in humans, joining SARS-CoV and MERS-CoV (Middle East Respiratory Syndrome-coronavirus). As with many infectious diseases, the immune response to coronavirus infection may act as a double-edged sword: necessary for promoting antiviral host defense, but, if not appropriately regulated, also able to incite life-threatening immunopathology. Key immunoregulatory mediators include the chemokines, a large family of leukocyte chemoattractants that coordinate leukocyte infiltration, positioning and activation in infected tissue by acting at specific G protein-coupled receptors. Here, we compare the involvement of chemokines and chemokine receptors during infection with the three epidemic coronaviruses and discuss their potential value as biomarkers and targets for therapeutic development.

Abstract
With the current national opioid crisis, it is critical to examine the mechanisms underlying pathophysiologic interactions between human immunodeficiency virus (HIV) and opioids in the central nervous system (CNS). Recent advances in experimental models, methodology, and our understanding of disease processes at the molecular and cellular levels reveal opioid-HIV interactions with increasing clarity. However, despite the substantial new insight, the unique impact of opioids on the severity, progression, and prognosis of neuroHIV and HIV-associated neurocognitive disorders (HAND) are not fully understood. In this review, we explore, in detail, what is currently known about mechanisms underlying opioid interactions with HIV, with emphasis on individual HIV-1-expressed gene products at the molecular, cellular and systems levels. Furthermore, we review preclinical and clinical studies with a focus on key considerations when addressing questions of whether opioid-HIV interactive pathogenesis results in unique structural or functional deficits not seen with either disease alone. These considerations include, understanding the combined consequences of HIV-1 genetic variants, host variants, and μ-opioid receptor (MOR) and HIV chemokine co-receptor interactions on the comorbidity. Lastly, we present topics that need to be considered in the future to better understand the unique contributions of opioids to the pathophysiology of neuroHIV. Blood-brain barrier and the neurovascular unit. With HIV and opiate co-exposure (represented below the dotted line), there is breakdown of tight junction proteins and increased leakage of paracellular compounds into the brain. Despite this, opiate exposure selectively increases the expression of some efflux transporters, thereby restricting brain penetration of specific drugs. ![]()

Abstract
A meta-analysis was carried out in this study by summarizing relevant research to evaluate the relationship between rs2107538 polymorphism in the chemotactic chemokine ligand 5 (CCL5) gene and tuberculosis (TB) susceptibility. Published studies were retrieved from PubMed, Embase, and CNKI databases using the keywords 'CCL5', 'TB', and 'polymorphism'. Nine studies involving 2584 patients with TB and 2265 controls were included in the current meta-analysis. The combined results suggested that the CCL5 rs2107538 polymorphism was correlated with TB susceptibility (recessive model: OR = 1.45, 95% CI = 1.02-2.07). Subgroup analysis according to race indicated that such correlation could be detected in Caucasians (CT versus CC: OR = 1.53, 95% CI = 1.20-1.95; dominant model: OR = 1.58, 95% CI = 1.25-1.99), but not in East Asian, South Asian, and South African populations. In conclusion, the results of our meta-analysis suggest that CCL5 rs2107538 polymorphism might contribute to the risk of TB, especially in Caucasians. Well-designed studies with more subjects will be required for further validation of these results.

Abstract
Certain host genetic variants, especially in the human leucocyte antigen (HLA) region, are associated with different progression of HIV-1-induced diseases and AIDS. Long term non progressors (LTNP) represent only the 2% of infected patients but are especially relevant because of their efficient HIV control. In this work we present a global analysis of genetic data in the large national multicenter cohort of Spanish LTNP, which is compared with seronegative individuals and HIV-positive patients. We have analyzed whether several single-nucleotide polymorphisms (SNPs) including in key genes and certain HLA-A and B alleles could be associated with a specific HIV phenotype. A total of 846 individuals, 398 HIV-1-positive patients (213 typical progressors, 55 AIDS patients, and 130 LTNPs) and 448 HIV-negative controls, were genotyped for 15 polymorphisms and HLA-A and B alleles. Significant differences in the allele frequencies among the studied populations identified 16 LTNP-associated genetic factors, 5 of which were defined for the first time as related to LTNP phenotype: the protective effect of HLA-B39, and the detrimental impact of HLA-B18, -A24, -B08 and –A29. The remaining eleven polymorphisms confirmed previous publications, including the protective alleles HLA-B57, rs2395029 (HCP5), HLA bw4 homozygosity, HLA-B52, HLA-B27, CCR2 V64I, rs9264942 (HLA-C) and HLA-A03; and the risk allele HLA bw6 homozygosity. Notably, individual Spanish HIV-negative individuals had an average of 0.12 protective HLA alleles and SNPs, compared with an average of 1.43 protective alleles per LTNP patient, strongly suggesting positive selection of LTNP. Finally, stratification of LTNP according to viral load showed a proportional relationship between the frequency of protective alleles with control of viral load. Interestingly, no differences in the frequency of protection/risk polymorphisms were found between elite controllers and LTNPs maintaining viral loads <2.000 copies/mL throughout the follow-up.

Abstract
Neurocognitive impairments associated with human immunodeficiency virus (HIV) infection remain a considerable health issue for almost half the people living with HIV, despite progress in HIV treatment through combination antiretroviral therapy (cART). The pathogenesis and risk factors of HIV-associated neurocognitive disorder (HAND) are still incompletely understood. This is partly due to the complexity of HAND diagnostics, as phenotypes present with high variability and change over time. Our current understanding is that HIV enters the central nervous system (CNS) during infection, persisting and replicating in resident immune and supporting cells, with the subsequent host immune response and inflammation likely adding to the development of HAND. Differences in host (human) genetics determine, in part, the effectiveness of the immune response and other factors that increase the vulnerability to HAND. This review describes findings from studies investigating the role of human host genetics in the pathogenesis of HAND, including potential risk factors for developing HAND. The similarities and differences between HAND and Alzheimer's disease are also discussed. While some specific variations in host genes regulating immune responses and neurotransmission have been associated with protection or risk of HAND development, the effects are generally small and findings poorly replicated. Nevertheless, a few specific gene variants appear to affect the risk for developing HAND and aid our understanding of HAND pathogenesis.

Abstract
Simian immunodeficiency virus (SIV) infection in rhesus macaques is often characterized by high viremia and CD4 T cell depletion. By contrast, SIV infection in African nonhuman primate natural hosts is typically nonpathogenic despite active viral replication. Baboons are abundant in Africa and have a geographical distribution that overlaps with natural hosts, but they do not harbor SIVs. Previous work has demonstrated baboons are resistant to chronic SIV infection and/or disease in vivo but the underlying mechanisms remain unknown. Using in vitro SIVmac infections, we sought to identify SIV restriction factors in baboons by comparing observations to the pathogenic rhesus macaque model. SIVmac replicated in baboon PBMC but had delayed kinetics compared to rhesus PBMC. However, SIVmac replication in baboon and rhesus isolated CD4 cells were similar to the kinetics seen for rhesus PBMC, demonstrating intracellular restriction factors do not play a strong role in baboon inhibition of SIVmac replication. Here, we show CD8 T cells contribute to the innate SIV-suppressive activity seen in naïve baboon PBMC. As one mechanism of restriction, we identified higher production of MIP-1α, MIP-1β, and RANTES by baboon PBMC. Contact between CD4 and CD8 T cells resulted in maximum production of these chemokines and suppression of viral replication, whereas neutralization of CCR5-binding chemokines in baboon PBMC increased viral loads. Our studies indicate baboon natural restriction of SIVmac replication is largely dependent on CD4-extrinsinc mechanisms mediated, in part, by CD8 T cells.

[PMID: 30296712 DOI: 10.1016/j.cyto.2018.10.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2018] [Revised: 09/17/2018] [Accepted: 10/03/2018] [Indexed: 12/11/2022]
Abstract
Although serum chemokine levels have been reported to influence the outcome of interferon-based treatment in patients with chronic hepatitis C, their effect on the hepatitis C virus (HCV) response to direct-acting antiviral agents (DAAs), which can achieve high rates of a sustained virological response (SVR), is largely unknown. To clarify this relationship, 9 chemokines (eotaxin, GRO-α, IL-8, IP-10, MCP-1, MIP-1α, MIP-1β, RANTES, and SDF-1α) were quantified before, during, and after DAA treatment using serum samples obtained from 57 patients with chronic hepatitis C. All baseline median chemokine levels were significantly higher in patients with chronic hepatitis C than in healthy subjects (P < 0.05). In particular, lower MIP-1β (≤71.5 pg/mL) and higher RANTES (>671.5 pg/mL) levels were significantly associated with patients who failed to clear HCV RNA (P = 0.0039 and 0.013, respectively). Prediction of a clinical response based on a combination of these chemokines demonstrated high sensitivity (82%), specificity (85%), negative predictive value (95%), and area under the curve (0.833). The non-SVR rate (56.3%; 9 of 16) was significantly higher in patients with low MIP-1β and high RANTES compared with other combinations. Moreover, baseline MIP-1β and RANTES were both additive and independent for predicting a non-SVR. Apart from an increase in eotaxin, all chemokines became decreased in patients with a SVR. In conclusion, a combination of serum MIP-1β and RANTES levels may be predictive of a treatment response to DAAs in Japanese patients with chronic hepatitis C.

Abstract
Platelets are essential effector cells in hemostasis. Aside from their role in coagulation, platelets are now recognized as major inflammatory cells with key roles in the innate and adaptive arms of the immune system. Activated platelets have key thromboinflammatory functions linking coagulation to immune responses in various infections, including in response to virus. Recent studies have revealed that platelets exhibit several pattern recognition receptors (PRR) including those from the toll-like receptor, NOD-like receptor, and C-type lectin receptor family and are first-line sentinels in detecting and responding to pathogens in the vasculature. Here, we review the main mechanisms of platelets interaction with viruses, including their ability to sustain viral infection and replication, their expression of specialized PRR, and activation of thromboinflammatory responses against viruses. Finally, we discuss the role of platelet-derived mediators and platelet interaction with vascular and immune cells in protective and pathophysiologic responses to dengue, influenza, and human immunodeficiency virus 1 infections.

Abstract
Background & objectives: Sahariya, a primitive tribe of Central India, has shown significantly increased incidence of pulmonary tuberculosis (PTB). Our previous study on Sahariya showed a significant association of −403G>A single nucleotide polymorphism (SNP) of CCL5 with susceptibility to PTB. Hence, this study was aimed to analyze a genotype-phenotype relationship of this disease-associated SNP to develop a potential diagnostic marker for TB in this tribe. Methods: The present study was carried out on 70 plasma samples from Sahariya tribe, wherein the plasma CCL5 level was determined using a commercially available ELISA kit. Results: The level of CCL5 decreased significantly in patients who were on therapy/completed their therapy [inactive TB patient/inactive PTB (IPTB)], particularly with AA genotype of −403G>A (P=0.046). The level, with AA genotype, was also found to gradually decrease in sputum 3+ and 1+/2+ than in sputum-negative samples. Similarly, the CCL5 level was found to be higher in sputum-positive/active TB patients than in IPTB group and healthy controls. Interpretation & conclusions: Our results suggested that the CCL5 level was influenced collectively not only by the genotypes of −403G>A SNP and bacillary load but also by the treatment. Thus, CCL5 may be considered for the development of a diagnostic marker and also as an indicator of recovery.

Abstract
Conventional hormone therapy (HT) containing estrogens such as ethinylestradiol (EE) have been associated with an increased risk of breast cancer and cardiovascular disease resulting in women seeking safer alternatives that are claimed to have fewer health risks. One such alternative gaining popularity, is custom-compounded bioidentical (b)HT formulations containing bioidentical estradiol (bE2) and estriol (bE3). However, the preparation of these custom-compounded estrogens is not regulated, and depending on the route of synthesis, steroid mixtures with differing activities may be produced. Thus, an investigation into the activities of estrogens prepared by custom-compounded pharmacies is warranted. The aim of this study was therefore to directly compare the pharmacological properties of bE2 and bE3 of unknown purity relative to commercially available, pure E2, E3 and estrone (E1) standards as well as synthetic EE used in conventional HT via the human estrogen receptor (ER)-α and -β. We determined precise equilibrium dissociation constants (Kd or Ki values) and showed that bE2 and bE3 display similar binding affinities to the E2 and E3 standards, while EE had a higher affinity for ERα, and E1 a lower affinity for ERβ. Furthermore, all the estrogens display similar agonist efficacies, but not potencies, for transactivation on a minimal ERE-containing promoter via the individual ER subtypes. Although E2 and E3 were equally efficacious and potent on the endogenous ERE-containing pS2 promoter in the MCF-7 BUS breast cancer cell line co-expressing ERα and ERβ, E1 was less efficacious and potent than E2. This study is the first to demonstrate that the bioidentical estrogens, commercially available estrogen standards and synthetic EE are full agonists for transrepression on both minimal and endogenous NFκB-containing promoters. Moreover, we showed that these estrogens all increase proliferation and anchorage-independent growth of MCF-7 BUS cells to a similar extent, suggesting that custom-compounded bHT may in fact not be a safer alternative to conventional HT. Furthermore, our results showing that E3 and E1 are not weak estrogens, and that E3 does not antagonize the activity of E2, suggest that the rationale behind the use of E3 and E1 in custom-compounded bHT formulations should be readdressed. Taken together, the results indicating that there is mostly no difference between the custom-compounded bioidentical estrogens, commercially available estrogen standards and synthetic EE, at concentrations reflecting serum levels in women using estrogen-containing HT, suggest that there is no clear advantage in choosing bHT above conventional HT.

Abstract
Introduction Polymorphic variants of MCP-1 and RANTES genes and their protein serum levels have been implicated in the increased risk and severity of several malignancies. However, the subject has not been explored in basal cell carcinoma (BCC) patients so far. Aim To investigate the association between monocyte chemoattractant protein 1 (MCP-1) (–2518 A/G) and RANTES (–403 G/A) polymorphism and risk and clinical course of BCC. Material and methods The study group consisted of 150 unrelated patients with BCC and 140 healthy, unrelated, age- and sex-matched volunteers. The polymorphisms were analysed using the amplification refractory mutation system polymerase chain reaction method (ARMS-PCR) and single specific primer-polymerase chain reaction (SSP-PCR). Serum cytokine levels were measured with ELISA. Results The presence of the MCP-1 –2518 GG genotype was statistically more frequent in BCC patients and it increased the risk of BCC (OR = 2.63, p = 0.003). Genotype –330 GG was statistically more common in patients with less advanced tumours (OR = 2.8, p = 0.017). Monocyte chemoattractant protein 1 serum level was statistically higher with GG genotype. In the BCC group MCP-1 serum levels were decreased. Neither polymorphic variants of RANTES nor the chemokine serum concentration differed significantly between the study groups. Conclusions These findings suggest that –2518 A/G MCP-1 polymorphism may be involved in BCC pathogenesis.

Abstract
OBJECTIVES To assess the association between chemotactic chemokine (C-C motif) ligand 5 (CCL5) -28C>G polymorphism and tuberculosis (TB) risk. METHODS PubMed, Web of Science, and WanFang were searched up to April 2015 for eligible studies on CCL5 -28C>G polymorphism. Data was extracted, and pooled odd ratios (ORs) as well as 95% confidence intervals (95% CI) were calculated. RESULTS Eight case-control studies were extracted from 8 articles on the polymorphism involving 1852 TB cases and 2068 controls. The results of meta-analysis showed that significant reduced risks were found for the polymorphism with the risk of TB in Asians and Arabs as follows: OR=0.12, 95% CI=0.06-0.26, p=0.000 for mutant homozygous (GG) versus wild-type homozygous (CC) for Asian descent, OR=0.14, 95% CI=0.07-0.28, p=0.000 for GG versus CC in the Arab descent. CONCLUSION Our findings demonstrated that CCL5 gene -28C>G polymorphism might be a protective factor for the development of TB.

Abstract
Previous studies have reported that two single nucleotide polymorphisms (SNPs) in the RANTES gene promoter region, -403G/A and -28C/G, are associated with a slower rate of decline in CD4+ T cell count. In addition, as a ligand of the major HIV coreceptor CCR5, it is known to block HIV-CCR5 interactions in the course of the HIV infection cycle. This study was carried out with the aim of determining the occurrence of single nucleotide polymorphisms (SNPs) -403G > A and -28C > G in the promoter region of RANTES, in a subset of the Kenyan population. Genomic DNA was extracted from peripheral blood monocular cells and used to amplify the RANTES gene region. Restriction fragment length polymorphism was used to determine the genotypes of the RANTES gene. Out of 100 HIV infected individuals, 19% had G1 genotypes (403G/G, 28C/G), 30% (403A/A, 28C/C), and 50% (403G/A, 28C/C), while in healthy blood donors 13% had G4 (403G/A, 28C/C) genotypes, 22% (403A/A, 28C/C), and 54% (403G/A, 28C/C). HIV negative blood donors (54%) had higher risk of alteration to risk of HIV transmission compared to those who were HIV infected (50%). However, the risk to transmission and distribution differences was not significant (P = 0.092). The study showed that RANTES polymorphisms -403 and -28 alleles do exist in the Kenyan population.

Abstract
Regulated upon activation, normal T-cell expressed and secreted (RANTES) is a beta-chemokine and has been detected in brain lesions of multiple sclerosis (MS) patients. Considering its potential role in MS, we screened two functional polymorphisms in the proximal promoter region of the RANTES in MS patients versus controls. Methods: We examined 140 postmortem brain samples from subjects with a primary diagnosis of MS, and peripheral blood samples from 216 control subjects. The RANTES-28C/G and -403G/A promoter polymorphisms were examined. All subjects were non-Hispanic Caucasians. Results: MS cases differed from controls showing a significant association with the 403G/A polymorphism (odds ratio, 2.359, [1.465-3.799]; P-0.0001), but not the -28C/G (P-NS) polymorphism. There was a significant association of the -28G allele with both early onset (P-0.031) and longer survival (P-0.006). Conclusion: There is a significant but complex association of the RANTES gene with MS.

Abstract
OBJECTIVE The role of CC chemokine receptor 5 (CCR5) and its ligand CCL5 on the pathogenesis of HIV infection has been well studied but not for HCV infection. Here, we investigated whether CCL5 haplotypes influence HIV and HCV seropositivity among 373 Caucasian people who inject drugs (PWID) from Estonia. METHODS Study included 373 PWID; 56% were HIV seropositive, 44% HCV seropositive and 47% co-infected. Four CCL5 haplotypes (A-D) were derived from three CCL5 polymorphisms (rs2107538/rs2280788/rs2280789) typed by Taqman allelic discrimination assays. The data of CCR5 haplotypes were used from our previous study. The association between CCL5 haplotypes with HIV and/or HCV seropositivity was determined using logistic regression analysis. RESULTS Possessing CCL5 haplotype D (defined by rs2107538A/rs2280788G/rs2280789C) decreased the odds of HCV seropositivity compared to those not possessing it (OR = 0.19; 95% CI 0.09-0.40), which remained significant after adjustment to co-variates (OR = 0.08; 95% CI 0.02-0.29). An association of this haplotype with HIV seropositivity was not found. In step-wise logistic regression with backward elimination CCL5 haplotype D and CCR5 HHG*1 had reduced odds for HCV seropositivity (OR = 0.28 95% CI 0.09-0.92; OR = 0.23 95% CI 0.08-0.68, respectively) compared to those who did not possess these haplotypes, respectively. CONCLUSIONS Our results suggest that among PWID CCL5 haplotype D and CCR5 HHG*1 independently protects against HCV. Our findings highlight the importance of CCL5 genetic variability and CCL5-CCR5 axis on the susceptibility to HCV.

Abstract
Chemokine receptors and ligands are crucial for extensive immune response against infectious diseases such as malaria, leishmaniasis, HIV and tuberculosis and a wide variety of other diseases. Role of chemokines are evidenced in the activation and regulation of immune cell migration which is important for immune response against diseases. Outcome of disease is determined by complex interaction among pathogen, host genetic variability and surrounding milieu. Variation in expression or function of chemokines caused by genetic polymorphisms could be associated with attenuated immune responses. Exploration of chemokine genetic polymorphisms in therapeutic response, gene regulation and disease outcome is important. Infectious agents in human host alter the expression of chemokines via epigenetic alterations and thus contribute to disease pathogenesis. Although some fragmentary data are available on chemokine genetic variations and their contribution in diseases, no unequivocal conclusion has been arrived as yet. We therefore, aim to investigate the association of CCR5-CCL5 and CCR2-CCL2 genetic polymorphisms with different infectious diseases, transcriptional regulation of gene, disease severity and response to therapy. Furthermore, the role of epigenetics in genes related to chemokines and infectious disease are also discussed.

Abstract
Associations of regulated on activation, normal T cell expressed and secreted (RANTES) -403G/A, -28C/G, and In1.1T/C polymorphisms with HIV-1 infection and the progression of HIV-1 disease have been widely reported with inconsistent results. To clarify this situation, we performed an updated meta-analysis of all available studies from PubMed, EMBASE, and the China National Knowledge Infrastructure. A total of 24 eligible studies involving more than 10,000 subjects were included. By using the healthy controls, we found that -403G/A polymorphism was significantly associated with reduced susceptibility to HIV-1 infection in G/A+A/A versus GG (odds ratio [OR] = 0.755, 95% confidence interval [CI] = 0.581-0.982); and a significantly decreased risk was also found for -28C/G polymorphisms (G vs. C, OR = 0.804, 95% CI = 0.696-0.927; G/G+C/G vs. C/C, OR = 0.826, 95% CI = 0.704-0.969). Whereas for In1.1T/C polymorphism, increased risk of HIV-1 infection was revealed (C vs. T, OR = 1.216, 95% CI = 1.047-1.430; T/C vs. T/T, OR = 1.68, 95% CI = 1.263-2.234; T/C+T/T vs. C/C, OR = 1.466, 95% CI = 1.147-1.875). Subgroup analyses by ethnicity showed significant association among Asians, but not among Caucasians. When HIV-1-exposed seronegative (HESN) controls were used, no significant association was detected. Moreover, -403G/A and -28C/G polymorphisms were also not associated with long-term nonprogressive HIV-1 infection (all p > .05). This meta-analysis suggests that RANTES -403G/A and -28C/G polymorphisms confer possible protection against HIV-1 infection, whereas In1.1T/C polymorphism may increase risk of HIV-1 infection, especially in Asians. These results may contribute to finding a theoretical basis for effective control strategies against HIV/AIDS. Further investigations are needed to validate our conclusions.

Abstract
Post-transplant diabetes mellitus (PTDM) is a common complication after solid organ transplantation, especially in recipients treated with calcineurin inhibitors. Previous studies suggest that chronic inflammation and chemokines play an important role in the pathogenesis of diabetes. Single-nucleotide polymorphisms (SNPs) can increase or decrease transcriptional activity and can change the production of chemokines. The aim of this study was to examine the association between CCL2 and CCL5 gene polymorphisms and the development of post-transplant diabetes mellitus. The study included 315 patients who received kidney transplants and were treated with calcineurin inhibitors. Patients were divided into two subgroups: with PTDM (n=43) and without PTDM (n=272). An additive model of univariate Cox regression analysis showed that the hazard of PTDM development was significantly positively associated with the number of CCL2 rs1024611 G alleles (HR 1.65; 95%CI 1.08-2.53; p=0.021). Multivariate Cox regression analysis, taking into the account the recipient's sex, age and BMI, as well as the number of G alleles of the CCL2 rs1024611 polymorphism, revealed that this polymorphism is an independent risk factor for post-transplant diabetes. The results of our study suggest an association between the CCL2 gene rs1024611 G allele and PTDM in patients treated with tacrolimus or cyclosporine.

Malar J 2015; 14:341. [PMID: 26341782 PMCID: PMC4560921 DOI: 10.1186/s12936-015-0875-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2015] [Accepted: 08/27/2015] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND The severity and outcome of malaria is influenced by host immunity in which chemokines such as Regulated upon Activation, Normal T cell Expressed and Secreted (RANTES) play an important role. Previous studies show that variations in the RANTES gene affect RANTES protein production, hence altering host immunity. In this study, the relationship between presence of mutations in RANTES and incidence of malaria in a cohort of children living in a malaria-endemic area of Uganda was determined. METHODS This was a longitudinal study comprising of 423 children aged between 6 months and 9 years, who were actively followed up for 1 year. Malaria episodes occurring in the cohort children were detected and the affected children treated with national policy drug regimen. Mutations in the RANTES gene were determined by PCR-RFLP method and their frequencies were calculated. A multivariate negative binomial regression model was used to estimate the impact of RANTES mutations on malaria incidence. In all statistical tests, a P-value of <0.05 was considered as significant. RESULTS The frequencies of the -403A and In1.1C allele were 53.7 and 19.2 %, respectively. No mutations were found at the -28 locus. After adjustment of incidence rates for age, blood group, insecticide-treated bed net (ITN) use, malaria history and the sickle cell trait, 1n1.1T/C heterozygotes and homozygotes showed a non-significant trend towards higher incidence rates compared to wild-type individuals (IRR = 1.10; P = 0.55 and IRR = 1.25; P = 0.60, respectively). Similarly, there was no significant difference in malaria incidence rates between RANTES -403G/A heterozygotes or homozygotes and those without mutations (IRR = 1.09; P = 0.66 and IRR = 1.16; P = 0.50, respectively). No relation was seen between RANTES polymorphisms, baseline parasite densities and the time to first re-infection after administration of anti-malaria drugs. CONCLUSIONS This study showed that the -403A mutation occurs in nearly half of the study population and the In1.1C allele occurs in one in every four children. Despite the high frequency of these mutations, there was no clear association with malaria incidence. Other studies evaluating more markers, that could potentially modulate RANTES gene transcription alongside other genetic modifiers of malaria susceptibility, may provide further explanations to these less dramatic findings.

Abstract
OBJECTIVE Chemokine (C-C motif) ligand 5 (CCL5) has been shown to play an important role in antimycobacterial immune responses. Previous studies have extensively reported that the CCL5 -28C>G gene polymorphism is associated with susceptibility to tuberculosis (TB). However, the results of these studies have been inconsistent. To investigate the relationship between the CCL5 -28C>G and the risk of TB, we performed a meta-analysis. METHODS We searched articles published before June 6, 2014 from PubMed, CNKI, and Wanfang databases. Data were extracted from all eligible publications independently by two investigators and statistically analyzed. Odds ratios (OR) with 95% confidence intervals (CI) were calculated to assess the strength of the association between CCL5 polymorphism and TB. RESULTS Four case-control studies including 647 TB cases and 726 controls were involved in the meta-analysis. Our meta-analysis indicated the CCL5 -28C>G gene polymorphism was significantly associated with increased risk of TB (G vs. C: 3.75, 95% CI = 1.76-7.99; GG vs. CC: OR = 30.26, 95% CI = 14.28-64.12). CONCLUSION Our results suggested that the -28C>G polymorphism is significantly associated with higher TB risk, which is opposite from previously published reports. However, the number of the study is limited, additional well-designed studies are required to elucidate the association between the CCL5 -28C>G gene polymorphism and TB.

Abstract
BACKGROUND Most hepatocellular carcinomas (HCCs) are diagnosed at an advanced stage. The prognostic value of serum tumour markers alpha-fetoprotein (AFP) and des-gamma-carboxy prothrombin (DCP) is limited. The aim of our study is to evaluate the diagnostic value of serum growth factors, apoptotic and inflammatory mediators of cirrhotic patients with and without HCC. METHODS Serum samples were collected from cirrhotic potential liver transplant patients (LTx) with (n=61) and without HCC (n=78) as well as from healthy controls (HCs; n=39). Serum concentrations of CRP, neopterin and IL-6 as markers of inflammation and thrombopoietin (TPO), GCSF, FGF basic and VEGF, HMGB1, CK-18 (M65) and CK18 fragment (M30) and a panel of proinflammatory chemokines (CCL2, CCL3, CCL4, CCL5, CXCL5 and IL-8) were measured. Chi square, Fisher exact, Mann-Whitney U-tests, ROC curve analysis and forward stepwise logistic regression analyses were applied. RESULTS Patients with HCC had higher serum TPO and chemokines (P<0.001 for TPO, CCL4, CCL5 and CXCL5) and lower CCL2 (P=0.008) levels than cirrhotic patients without HCC. Multivariate forward stepwise regression analysis for significant parameters showed that among the studied parameters CCL4 and CCL5 (P=0.001) are diagnostic markers of HCC. Serum levels of TPO and chemokines were lower, whereas M30 was significantly higher in cirrhotic patients than in HCs. CONCLUSIONS High serum levels of inflammatory chemokines such as CCL4 and CCL5 in the serum of cirrhotic patients indicate the presence of HCC.

Abstract
Background The association between chemotactic chemokine ligand 5 (CCL5) -403G/A gene polymorphism and human immunodeficiency virus-1 (HIV-1) infection has been illustrated among several case-control studies, but the conclusions are still inconsistent. Here we performed a meta-analysis to estimate the association. Methods The published studies based upon the association between CCL5 -403G/A polymorphism and HIV-1 infection were retrieved from PubMed, Embase, and China National Knowledge Infrastructure database. Quantitative synthesis, including pooled odds ratios (ORs) and 95% confidence intervals (CIs), was performed for all genetic models. Results A total of ten studies consisting of 5,127 subjects were included for this meta-analysis. There was no association found between -403G/A polymorphism and HIV-1 infection in the overall analysis under any genetic models. Further stratified by ethnicity, our analysis showed that -403A/A polymorphism significantly decreased the susceptibility to HIV-1 infection in three models: the dominant model (AA+AG vs GG: OR =0.44, 95% CI =0.21–0.94) among Africans, the homozygous model (AA vs GG: OR =0.62, 95% CI =0.242–0.90), and the recessive model (AA vs GG+AG: OR =0.62, 95% CI =0.45–0.93) among Asians. Conclusion We found that only Asians and Africans with CCL5 -403A/A polymorphism could be resistant to HIV-1 infection. However, further studies should be performed to evaluate this association on ethnic basis against control groups consisting of individuals who have once been exposed to HIV-1 but are seronegative.

Abstract
BACKGROUND A few recent studies have suggested that regulated on activation, normal T cell expressed and secreted (RANTES) polymorphisms (-403 G/A, -28C/G) are associated with asthma. However, there still existed studies which did not confirm these correlations. OBJECTIVE The objective of this study was to evaluate the relationship of RANTES and asthma using a meta-analysis. METHODS Pubmed, Embase, and Cochrane library databases were systemically searched. Data were extracted by two independent reviewers and pooled odds ratio (OR) with 95% confidence interval (CI) were calculated. RESULTS Eighteen studies were enrolled, including a total of 2558 cases and 2630 controls of -403 G/A, as well as 3311 cases and 4031 controls of -28C/G in this meta-analysis. The overall ORs and 95% CIs of -403 G/A were 1.19, 1.06-1.33 (P<0.001) and 1.25, 1.03-1.51 (P = 0.933) in dominant and recessive models, respectively. The overall ORs and 95% CIs of -28G were 1.23, 1.09-1.39 (P = 0.221) and 1.76, 1.32-2.34 (P = 0.356) in dominant and recessive models, respectively. No publication bias among studies was showed. CONCLUSIONS This meta-analysis showed that RANTES -403 G/A polymorphism was a risk factor for asthma, while -28C/G polymorphism were not associated with asthma.

Abstract
Several studies have shown the correlation between RANTES gene and inflammatory disorders; the aim of the present study was to investigate the association between RANTES promoter gene polymorphism and Meniere's disease (MD) in an Iranian population. In this study patients with MD comprising definite MD (N = 56) and probable MD (N = 15) were selected according to diagnostic criteria of AAO-HNS. The control group (N = 101) were healthy normal subjects who did not have a history of ear disease and vertigo. PCR-RFLP for RANTES -403G>A has been performed. We found a protective role for RANTES -403A allele in male group in our population. None of the male patients with MD were carrier of allele A which was significantly different from the presence of allele A in the male control group (AA+GA vs. GG: p = 0.0004, OR 0.05, 95 % CI 0.001-0.39). This difference was not significant in female group. There was no significant association between RANTES gene polymorphism and the level of hearing loss. our results showed a sex-specific association between RANTES gene polymorphism and MD but more studies are necessary to further assess this association.

Abstract
A complex interaction of genetic and environmental factors is closely associated with the development of inflammatory bowel disease. Previous studies reported that the expression of the regulated upon activation, normal T-cell expressed and secreted (RANTES) gene is enhanced in the colonic mucosa of ulcerative colitis (UC). Quantitative differences in RANTES gene expression among numerous promoter genotypes have also been reported. The aim of the present study was to clarify the effect of RANTES promoter polymorphism on the risk of UC, including its clinical phenotypes. A total of 150 UC patients and 372 healthy control (HC) subjects participated in the study. The UC patients were classified by disease behavior, severity and extent of disease. Restriction fragment length polymorphism analysis was performed for polymorphisms at -28 C/G in the RANTES gene promoter region. Although no significant difference of the RANTES promoter genotype distribution was observed between the HC and UC groups, the G/G genotype was significantly higher among female (OR=3.95, 95% CI=1.22-12.82, P=0.03), non-steroid dependent (OR=3.37, 95% CI=1.16-9.85, P=0.03) and non-refractory (OR=3.76, 95% CI=1.29-10.98, P=0.02) UC patients. The G carrier was also found to be associated with an increased risk of rectal colitis (OR=2.21, 95% CI=1.12-4.39, P=0.03). The data indicate that the polymorphism of the RANTES promoter is not directly associated with the susceptibility to UC, but the -28 G allele is associated with female UC patients and mild clinical phenotypes of UC, including non-steroid dependency, non-refractory and rectal colitis.

Abstract
The Human Genome Project, coupled with rapidly evolving high-throughput technologies, has opened the possibility of identifying heretofore unknown biological processes underlying human disease. Because of the opaque nature of HIV-associated neurocognitive disorder (HAND) neuropathogenesis, the utility of such methods has gained notice among NeuroAIDS researchers. Furthermore, the merging of genetics with other research areas has also allowed for application of relatively nascent fields, such as neuroimaging genomics, and pharmacogenetics, to the context of HAND. In this review, we detail the development of genetic, transcriptomic, and epigenetic studies of HAND, beginning with early candidate gene association studies and culminating in current "omics" approaches that incorporate methods from systems biology to interpret data from multiple levels of biological functioning. Challenges with this line of investigation are discussed, including the difficulty of defining a valid phenotype for HAND. We propose that leveraging known associations between biology and pathology across multiple levels will lead to a more reliable and valid phenotype. We also discuss the difficulties of interpreting the massive and multitiered mountains of data produced by current high-throughput omics assays and explore the utility of systems biology approaches in this regard.

The longitudinal and interactive effects of HIV status, stimulant use, and host genotype upon neurocognitive functioning. J Neurovirol 2014; 20:243-57. [PMID: 24737013 DOI: 10.1007/s13365-014-0241-y] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2013] [Revised: 01/29/2014] [Accepted: 02/06/2014] [Indexed: 12/18/2022]
Abstract
Both human immunodeficiency virus (HIV)-1 infection and illicit stimulant use can adversely impact neurocognitive functioning, and these effects can be additive. However, significant variability exists such that as-of-yet unidentified exogenous and endogenous factors affect one's risk for neurocognitive impairment. Literature on both HIV and stimulant use indicates that host genetic variants in immunologic and dopamine-related genes are one such factor. In this study, the individual and interactive effects of HIV status, stimulant use, and genotype upon neurocognitive functioning were examined longitudinally over a 10-year period. Nine hundred fifty-two Caucasian HIV+ and HIV- cases from the Multicenter AIDS Cohort Study were included. All cases had at least two comprehensive neurocognitive evaluations between 1985 and 1995. Pre-highly active antiretroviral therapy (HAART) data were examined in order to avoid the confounding effect of variable drug regimens. Linear mixed models were used, with neurocognitive domain scores as the outcome variables. No four-way interactions were found, indicating that HIV and stimulant use do not interact over time to affect neurocognitive functioning as a function of genotype. Multiple three-way interactions were found that involved genotype and HIV status. All immunologically related genes found to interact with HIV status affected neurocognitive functioning in the expected direction; however, only C-C chemokine ligand 2 (CCL2) and CCL3 affected HIV+ individuals specifically. Dopamine-related genetic variants generally affected HIV-negative individuals only. Neurocognitive functioning among HIV+ individuals who also used stimulants was not significantly different from those who did not use stimulants. The findings support the role of immunologically related genetic differences in CCL2 and CCL3 in neurocognitive functioning among HIV+ individuals; however, their impact is minor. Being consistent with findings from another cohort, dopamine (DA)-related genetic differences do not appear to impact the longitudinal neurocognitive functioning of HIV+ individuals.

Gene polymorphisms in CCR5, CCR2, SDF1 and RANTES among Chinese Han population with HIV-1 infection. INFECTION GENETICS AND EVOLUTION 2014; 24:99-104.

Abstract
Chemokines and chemokine receptors are crucial for immune response in HIV-1 infection. Although many studies have been done to investigate the relationship between chemokines and chemokine receptor gene polymorphisms and host's susceptibility to HIV-1 infection, the conclusions are under debate. In the present study, a cohort of 287 HIV-1 seropositive patients, 388 ethnically age-matched healthy controls and 49 intravenous drug users (IDUs) HIV-1 exposed seronegative individuals (HESN) from Chinese Han population were enrolled in order to determine the influence of host genetic factors on HIV-1 infection. Seven polymorphisms on four known chemokines/chemokine receptor genes (CCR5Δ32, CCR5 m303, CCR5 59029A/G, CCR2 64I, RANTES -403A/G, RANTES -28C/G and SDF1 3'-A) were screened. CCR5Δ32 and CCR5 m303 were absent or infrequent in Chinese Han population, which may not be hosts' genetic protective factors for HIV-1 infection. Our results showed the CCR5 59029A/G, CCR2 64I and SDF1 3'-A were not associated with host's resistance to HIV-1 infection. The frequency of RANTES -403A allele was significantly lower in HIV-1 patients than in healthy blood donors (p=0.0005) and HESN group (p=0.035), which implied the association between A allele and reduced HIV-1 infection risk. Different genetic models were assessed to investigate this association (AA vs. GG+AG, OR=0.38 95% CI, 0.22-0.65 p=0.0004; A vs. G, OR=0.66 95% CI, 0.52-0.84 p=0.0006), which supported this association, either. The genotype and allele distribution of RANTES -28 between HIV-1 patients and healthy controls (genotype profile: p=0.072; allele profile: p=0.027) or HIV-1 seronegative group (genotype profile: p=0.036; allele profile: p=0.383) were both at the marginal level of significance, which were not observed after Bonferroni correction. All these results suggest the RANTES -403A may be associated with reduced susceptibility to HIV-1 infection, while the RANTES -28 locus not. By lack of the patients' clinical information, whether these polymorphisms affect AIDS disease progression and their role in different HIV-1 infection routes could not performed in present study and needs to be assessed in ongoing studies.

Abstract
Considerable insight has been gained into the comorbid, interactive effects of HIV and drug abuse in the brain using experimental models. This review, which considers opiates, methamphetamine, and cocaine, emphasizes the importance of host genetics and glial plasticity in driving the pathogenic neuron remodeling underlying neuro-acquired immunodeficiency syndrome and drug abuse comorbidity. Clinical findings are less concordant than experimental work, and the response of individuals to HIV and to drug abuse can vary tremendously. Host-genetic variability is important in determining viral tropism, neuropathogenesis, drug responses, and addictive behavior. However, genetic differences alone cannot account for individual variability in the brain "connectome." Environment and experience are critical determinants in the evolution of synaptic circuitry throughout life. Neurons and glia both exercise control over determinants of synaptic plasticity that are disrupted by HIV and drug abuse. Perivascular macrophages, microglia, and to a lesser extent astroglia can harbor the infection. Uninfected bystanders, especially astroglia, propagate and amplify inflammatory signals. Drug abuse by itself derails neuronal and glial function, and the outcome of chronic exposure is maladaptive plasticity. The negative consequences of coexposure to HIV and drug abuse are determined by numerous factors including genetics, sex, age, and multidrug exposure. Glia and some neurons are generated throughout life, and their progenitors appear to be targets of HIV and opiates/psychostimulants. The chronic nature of HIV and drug abuse appears to result in sustained alterations in the maturation and fate of neural progenitors, which may affect the balance of glial populations within multiple brain regions.

Abstract
AIM The CC chemokine ligand 5 (CCL5), plays a key role in the inflammatory response by recruiting mononuclear cells during tuberculosis (TB) infection. Association studies of CCL5 -28 C>G (rs2280788) polymorphism and TB risk have shown inconsistent and contradictory results among different ethnic populations. The aim of this meta-analysis is to investigate the association between CCL5 -28 C>G polymorphism and TB susceptibility. METHODOLOGY We performed quantitative synthesis for published studies based upon association between CCL5 -28 C>G polymorphism and TB risk from PubMed (Medline), EMBASE web databases. The meta-analysis was performed and pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated for all genetic models. RESULTS A total of six studies including 1324 TB cases and 1407 controls were involved in this meta-analysis. Variant allele (G vs. C: p = 0.257; OR = 1.809, 95% CI = 0.649 to 5.043), heterozygous (CG vs. CC: p = 0.443; OR = 1.440, 95% CI = 0.567 to 3.658) and homozygous (GG vs. CC: p = 0.160; OR = 5.140, 95% CI = 0.524 to 50.404) carriers did not show increased risk compare with those individual with the CC genotype. Similarly, no associations were found in the dominant (GG+CG vs. CC: p = 0.295; OR = 1.802, 95% CI = 0.599 to 5.412) and recessive (GG vs. CC+CG: p = 0.188; OR = 3.533, 95% CI = 0.541 to 23.085) models. CONCLUSIONS Overall findings of this meta-analysis suggest that genetic polymorphism -28 C>G in CCL5 is not associated with increased TB risk. However, future larger studies with group of populations will be needed to analyze the relationship between the CCL5 -28 C>G polymorphism and risk of TB.

Abstract
The aims of this study were to elucidate the association between RANTES-403 and an increased risk of gastric cancer in Korean males and to investigate the gene-gene interaction between IL-1B and RANTES. In total, 218 male patients with gastric cancer (114 diffuse types, 97 intestinal types, and 7 mixed types) and 377 male controls were included. RANTES-403 was genotyped, and age-adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were estimated by logistic regression. A multifactor dimensionality reduction (MDR) test with three-way split interval validation confirmed by likelihood ratio and permutation analysis was carried out. A significant increase in the risk of gastric cancer for the intestinal-type group was observed for IL-1B-1464G carriers (OR = 2.535; 95% CI = 1.121-5.732; P = 0.02) as well as for those with IL-1B-1464 CG (OR = 2.342; 95% CI = 0.998-5.500; P = 0.05) or IL-1B-1464 GG (OR = 2.819; 95% CI = 1.170-6.793; P = 0.02). For the RANTES-403 genotype, there was no significant difference in the risk of gastric cancer between the overall gastric cancer and the control groups. When further stratified according to histological types, RANTES-403A carriers (OR = 1.743; 95% CI = 1.086-2.798; P = 0.021) or heterozygotes (OR = 1.791; 95% CI = 1.092-2.935; P = 0.021) showed increased risk for developing diffuse-type gastric cancer. MDR revealed a three-way locus-locus interaction between RANTES-403AA, IL-1B-1464GG, and IL-1B-511CT for diffuse-type gastric cancer in Korean males. We demonstrated that RANTES-403 was significantly associated with the risk of developing diffuse-type gastric cancer in men and found a possible gene-gene interaction between RANTES and IL-1B polymorphisms in gastric cancer carcinogenesis.

Abstract
The CD8+ T cell effector mechanisms that mediate control of HIV-1 and SIV infections remain poorly understood. Recent work suggests that the mechanism may be primarily non-lytic. This is in apparent conflict with the observation that SIV and HIV-1 variants that escape CD8+ T cell surveillance are frequently selected. Whilst it is clear that a variant that has escaped a lytic response can have a fitness advantage compared to the wild-type, it is less obvious that this holds in the face of non-lytic control where both wild-type and variant infected cells would be affected by soluble factors. In particular, the high motility of T cells in lymphoid tissue would be expected to rapidly destroy local effects making selection of escape variants by non-lytic responses unlikely. The observation of frequent HIV-1 and SIV escape poses a number of questions. Most importantly, is the consistent observation of viral escape proof that HIV-1- and SIV-specific CD8+ T cells lyse infected cells or can this also be the result of non-lytic control? Additionally, the rate at which a variant strain escapes a lytic CD8+ T cell response is related to the strength of the response. Is the same relationship true for a non-lytic response? Finally, the potential anti-viral control mediated by non-lytic mechanisms compared to lytic mechanisms is unknown. These questions cannot be addressed with current experimental techniques nor with the standard mathematical models. Instead we have developed a 3D cellular automaton model of HIV-1 which captures spatial and temporal dynamics. The model reproduces in vivo HIV-1 dynamics at the cellular and population level. Using this model we demonstrate that non-lytic effector mechanisms can select for escape variants but that outgrowth of the variant is slower and less frequent than from a lytic response so that non-lytic responses can potentially offer more durable control. The interplay between viruses and the immune system cannot always be studied with current experimental techniques or commonly used mathematical models. Consequently, many important questions remain unanswered. The questions we wished to address fall into this category. Recent evidence strongly suggests that CD8+ T cells control SIV, and potentially HIV-1, primarily by secreting anti-viral factors rather than by killing infected cells. However, this does not seem compatible with the common observation that HIV and SIV evolve to escape the immune response. Soluble anti-viral factors, like RANTES which protects uninfected cells from infection, would be expected to inhibit both wild-type and variant virus. Furthermore, the high speed and motility of T cells in lymphoid tissue will increase homogeneity and again decrease the likelihood that an escape variant can have a selective advantage in the face of non-lytic control. We wanted to understand whether viral escape is proof that HIV-1- and SIV-specific CD8+ T cells kill infected cells, determine the factors that facilitate viral escape, and investigate the comparative efficiency of lytic and non-lytic responses in controlling viral infections. Here we develop an elaborate but robust computational framework that captures T cell kinetics and spatial interactions in lymphoid tissue to addresses these important questions.

Abstract
HIV and human defense mechanisms have co-evolved to counteract each other. In the process of infection, HIV takes advantage of cellular machinery and blocks the action of the host restriction factors (RF). A small subset of HIV+ individuals control HIV infection and progression to AIDS in the absence of treatment. These individuals known as long-term non-progressors (LNTPs) exhibit genetic and immunological characteristics that confer upon them an efficient resistance to infection and/or disease progression. The identification of some of these host factors led to the development of therapeutic approaches that attempted to mimic the natural control of HIV infection. Some of these approaches are currently being tested in clinical trials. While there are many genes which carry mutations and polymorphisms associated with non-progression, this review will be specifically focused on HIV host RF including both the main chemokine receptors and chemokines as well as intracellular RF including, APOBEC, TRIM, tetherin, and SAMHD1. The understanding of molecular profiles and mechanisms present in LTNPs should provide new insights to control HIV infection and contribute to the development of novel therapies against AIDS.

Abstract
Systemic lupus erythematosus (SLE) is a chronic and complex autoimmune disease characterized by the production of autoantibodies against a spectrum of nuclear antigens. RANTES and its receptor CCR5 have been associated with the pathogenesis of SLE. The objective of this study is to analyze autoantibodies (DNA/RNA), allelic distribution of RANTES and the association of levels of RANTES and its receptor CCR5 in SLE patients in North Indian region. The RANTES-403 and RANTES-28 polymorphism in the promoter region of RANTES gene was studied in 80 patients and 80 healthy controls. The levels of chemokine RANTES, its receptor CCR5, anti-dsDNA, and anti-SSA antibodies levels were determined. Disease activity was assessed with the systemic lupus erythematosus disease activity index (SLEDAI) score. All the parameters were studied for statistical analysis by using t test (graph pad prism) and correlation by SPSS data. PCR-RFLP performed showed 28C/C and the 403G/G genotypes in both patients and controls, but no other genotypes such as 28C/G, 28G/G and 403A/G, 403A/A were found. Patients had higher levels of RANTES (1840.48 ± 739.42 vs. 835.44 ± 70.48 pg/ml; P < 0.0001) and its receptor CCR5 expression (26.49 ± 0.16 vs. 24.72 ± 3.02 %; P < 0.05) compared to controls. The levels of autoantibodies anti-dsDNA and anti-SSA were also higher in patients than controls. The patients showing elevated anti-dsDNA had negative correlation with SLEDAI score (P < 0.05) while borderline patients were not found to be correlated. In case of anti-Ro/anti-SSA antibody levels, the borderline patients showed a moderately significant negative correlation as compared to controls than patients with elevated autoantibody (P < 0.01). The levels of RANTES and CCR5 were also higher in case of patients than controls. But there was no significant correlation of RANTES and CCR5 with disease activity. We were unable to find an association of RANTES polymorphism with SLE in North Indian population in our sample. No significant difference in allele distribution of RANTES-28 and RANTES-403 in the sample of 160 individuals was detected. Of the two autoantibodies studied, anti-Ro/anti-SSA levels in borderline lupus patients appeared as an important parameter for monitoring/diagnosis of lupus patients.

Abstract
OBJECTIVE To investigate the genetic determinants for developing tuberculosis in Sudan. METHODS Case study of 232 patients with tuberculosis and 206 healthy matched controls from Sudan. In the study population, three single nucleotide polymorphisms (SNPs) in the promoter regions of CCL5 and two in the promoter region of IL-10 were genotyped using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). These five SNPs influence the expression of these genes. RESULTS There were significant differences in allele distribution for CCL5 -28 C/G (rs 2280788) and IL-10 -592 A/C (rs1800872) in patients with tuberculosis compared with healthy controls. CONCLUSION This indicates that the genotypes obtained for CCL5 and IL-10 are associated with an increased risk of developing active TB.

Gong Z, Tang J, Xiang T, Zhang L, Liao Q, Liu W, Wang Y. Association between regulated upon activation, normal T cells expressed and secreted (RANTES) -28C/G polymorphism and susceptibility to HIV-1 infection: a meta-analysis. PLoS One 2013; 8:e60683. [PMID: 23577146 PMCID: PMC3618220 DOI: 10.1371/journal.pone.0060683] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2012] [Accepted: 03/01/2013] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Many studies have investigated the distributions of RANTES genotypes between HIV-1 infected patients and uninfected individuals. However, no definite results have been put forward about whether the RANTES -28C/G polymorphism can affect HIV-1 susceptibility. METHODS We performed a meta-analysis of 12 studies including 7473 subjects for whom the RANTES -28C/G polymorphism was genotyped. Odds ratios (ORs) with 95% confidence intervals (CIs) were employed to assess the association of the polymorphism with HIV-1 susceptibility. By dividing the controls into healthy controls and HIV-1 exposed but seronegative (HESN) controls, we explored the both allelic and dominant genetic models. RESULTS By using the healthy controls, we found a marginally significant association between the -28C/G polymorphism and susceptibility to HIV-1 infection in the allelic model (OR = 0.82, 95%CI = 0.70-0.97). But sensitivity analysis suggested that the association was driven by one study. We further performed stratified analysis according to ethnicity. The -28G allele decreased susceptibility to HIV-1 infection in the allelic model among Asians (OR = 0.79, 95%CI = 0.66-0.94). By using the HESN controls, no association between the polymorphism -28C/G and the susceptibility to HIV-1 infection was revealed in either the allelic model (OR = 0.84, 95%CI = 0.60-1.17) or the dominant model (OR = 0.77, 95%CI = 0.54-1.10). CONCLUSIONS Our findings suggested that the RANTES -28G allele might play a role in resistance to HIV-1 infection among Asians. Additional well-designed studies were required for the validation of this association.

Abstract
We investigated the association between RANTES (regulated upon activation, normal T cell expressed and secreted) polymorphisms and clinical outcomes in patients treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT). Three RANTES gene polymorphisms, i.e., -403G/A (rs2107538), -28C/G (rs2280788) and In1.1T/C (rs2280789), were genotyped, and the effects of the genotypes and haplotypes of RANTES on clinical outcomes were analyzed. The competing risk regression analysis was used to investigate the relationship between the polymorphisms and the cumulative risk of graft-versus-host disease (GVHD). An AGC haplotype in a recessive model showed significant harmful effects on the cumulative risk of acute GVHD and relapse-free survival (adjusted hazard ratios 2.42 and 2.71, 95% confidence intervals 1.29-4.55 and 1.30-5.64; p = 0.018 and 0.024, respectively), whereas a GCT haplotype did not. RANTES polymorphisms were not significantly associated with overall survival and the risk of chronic GVHD. This study suggests that RANTES polymorphisms might be associated with the occurrence of acute GVHD rather than of chronic GVHD and also of relapse-free survival in the patients treated with allo-HSCT. Further larger prospective investigations are needed to establish the role of RANTES polymorphisms in patients treated with allo-HSCT.
