Abstract
Human leukocyte antigens (HLA) alleles may affect the development of cervical cancer through immunologic control of human papillomavirus (HPV). The association between HLA-DQB1 alleles and risk of cervical cancer has been extensively studied, but the results obtained remain inconsistent. To explore a more extensive role of HLA-DQB1 alleles on cervical cancer risk, we carried out a meta-analysis including 4862 cases and 8988 controls from 22 published studies. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the strength of the association. The overall results suggested that HLA-DQB1*02 (OR=0.91, 95% CI=0.82-0.99), *03 (OR=0.85, 95% CI=0.74-0.97) and *0603 (OR=0.62, 95% CI=0.53-0.72) had a significantly association with decreased cervical cancer risk. In contrast, DQB1*05 (OR=1.18, 95% CI=1.01-1.38), *0301 (OR=1.14, 95% CI=1.06-1.23) and *0402 (OR=1.31, 95% CI=1.04-1.64) conferred a significantly higher risk to cervical cancer. Moreover, a significantly association with increased or decreased cervical cancer risk was found among Europeans and Asians after stratification of the HLA-DQB1 alleles by ethnicity. These findings supported that the HLA-DQB1 alleles may contribute to genetic susceptibility of cervical cancer. Further studies with a greater number of cases are expected to confirm our results.

Abstract
BACKGROUND Persistent infection with high-risk human papillomavirus (HPV) is a major risk factor for malignant lesions and cervical cancer. A widely studied element in the search for genetic factors influencing risk HPV infection diseases is allelic variation of the human leukocyte antigen (HLA) locus. The study was designed to search for HLA susceptibility alleles contributing to the persistence of HPV infection in Mexican women. METHODS A total of 172 subjects were divided into three groups: 1) HPV-persistent patients; 2) HPV-cleared; and 3) HPV-reinfected patients. They were screened for HPV types using a polymerase chain reaction (PCR). PCR-sequence specific oligonucleotide probes (PCR-SSOP) was used for HLA DRB1 and DQB1 typing. RESULTS We observed that HLA-DQB1*0501 allele might be associated with susceptibility of reinfection with HPV (p = 0.01, OR = 4.9, CI 95% = 1.3 -18.7). Allele frequency of HLA-DRB1*14 was particularly reduced in patients with cancer when compared with the HPV-persistent group (p = 0.04), suggesting that this allele is a possible protective factor for the development of cervical cancer (OR = 2.98). HLA-DRB1*07 might be associated with viral clearance (p = 0.04). CONCLUSIONS Genetic markers for HPV infection susceptibility are different in each population, in Mexicans several HLA-DQB1 alleles might be associated with an enhanced risk for viral persistence. In contrast, DRB1*14, seems to confer protection against cervical cancer.

Abstract
NK cells are a major group of immune cells responsible for the phenomenon of natural, innate cytotoxicity. One of the better studied receptors of human NK cells are killer cell immunoglobulin-like receptors (KIR) responsible for checking the presence of MHC class I molecules, which serve as their ligands. Although previously treated as specific for NK cells, nowadays these receptors are known to also occur on T cells. Genetics of KIR molecules is very complicated, what create a great variability of haplotypes in various populations world-wide. In addition, some KIR are known to recognize HLA-C (epitopes C1 or C2), HLA-B (Bw4) or HLA-A (A3 and/or A11) molecules. Therefore, this makes a huge diversity of reactions among individuals, depending on the presence or absence of given KIR and their ligands, hence differential susceptibility to several diseases, including various dermatoses. This paper underlines the important role of both KIR genotypes and HLA class I genes with reference to the various skin diseases.

Abstract
OBJECTIVE Human leukocyte antigens (HLA) play an important role in presenting virus antigens to immune cells that are responsible for the clearance of virus-infected cells and tumor cells. Herein, we evaluated whether genetic variants of HLA-DP and HLA-DQ are associated with cervical cancer risk. METHODS We genotyped four single nucleotide polymorphisms (SNPs) in HLA-DP (rs3077 and rs9277535) and HLA-DQ (rs2856718 and rs7453920) in a two-stage case-control study with a total of 2317 cervical cancer cases and 2109 cancer-free controls using TaqMan allelic discrimination assay. RESULTS We found consistently significant associations of HLA-DP rs3077 and rs9277535 with increased risks of cervical cancer (dominant genetic model: adjusted OR=1.51, 95% CI=1.32-1.71 for rs3077; adjusted OR=1.29, 95% CI=1.12-1.49 for rs9277535). When combining the effects of HLA-DP rs3077 and rs9277535, subjects carrying "≥1" variant alleles had a 1.55-fold increased risk of cervical cancer (95% CI=1.32-1.81), compared with those carrying "0" variant allele. And cervical cancer risk significantly increased with the increasing number of variant alleles of the two SNPs in a dose-dependent manner (P for trend=4.33×10(-10)). However, there were no significant associations for HLA-DQ rs2856718 and rs7453920 in our population. CONCLUSIONS These findings indicate that HLA-DP rs3077 and rs9277535 were candidate susceptibility markers for cervical cancer in Chinese females. Further validation studies with different ethnic background, biological function analyses and especially HPV typing together were needed.

Abstract
Cervical cancer is the second most common cancer in women worldwide. This is caused by oncogenic types of human papillomavirus (HPV) infection. Although large numbers of young sexually active women get HPV-infected, only a small fraction develop cervical cancer. This points to different co-factors for regression of HPV infection or progression to cervical cancer. Host genetic factors play an important role in the outcome of such complex or multifactor diseases such as cervical cancer and are also known to regulate the rate of disease progression. The aim of this review is to compile the advances in the field of host genetics of cervical cancer. MEDLINE database was searched using the terms, ‘HPV’, ‘cervical’, ‘CIN’, ‘polymorphism(s)’, ‘cervical’+ *the name of the gene* and ‘HPV’+ *the name of the gene*. This review focuses on the major host genes reported to affect the progression to cervical cancer in HPV infected individuals.

Abstract
We have conducted a pathway-based analysis of genome-wide single-nucleotide polymorphism (SNP) data in order to identify genetic susceptibility factors for cervical cancer in situ. Genotypes derived from Affymetrix 500k or 5.0 arrays for 1076 cases and 1426 controls were analyzed for association, and pathways with enriched signals were identified using the SNP ratio test. The most strongly associated KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways were Asthma (empirical P=0.03), Folate biosynthesis (empirical P=0.04) and Graft-versus-host disease (empirical P=0.05). Among the 11 top-ranking pathways were 6 related to the immune response with the common denominator being genes in the major histocompatibility complex (MHC) region on chromosome 6. Further investigation of the MHC revealed a clear effect of HLA-DPB1 polymorphism on disease susceptibility. At a functional level, DPB1 alleles associated with risk and protection differ in key amino-acid residues affecting peptide-binding motifs in the extracellular domains. The results illustrate the value of pathway-based analysis to mine genome-wide data, and point to the importance of the MHC region and specifically the HLA-DPB1 locus for susceptibility to cervical cancer.

Abstract
A detailed analyses of HPV-specific immunity was performed in a large group of patients with HPV-induced cervical cancer (CxCa) in relation to HLA-types and prognostic factors. Patients were HLA-typed and HPV16/18-specific T-cell immunity was assessed by proliferation assay and cytometric bead array using freshly isolated PBMC and by phenotypic analysis of HPV-specific T cells. The results were analyzed in relation to known disease-related HLA-types (DR7, DR13, DR15/DQ06), invasion-depth and size of tumor, lymph node (LN) status and disease free survival. In total 119 HLA-typed patients with CxCa were analyzed. Patients expressing the HLA-DR13 haplotype were underrepresented as compared to the Dutch population (p = 0.014), whereas HLA-DR7 was overrepresented in patients with HPV16+ CxCa (p = 0.006). In 29 of 94 patients (31%) from whom blood could be tested, a proliferative response to HPV16/18 was detected, which was associated with increased numbers of HPV-specific CD4+CD25+ (activated) T cells (p = 0.03) and HPV-specific CD4+CD25+FoxP3-positive T cells (p = 0.04). The presence of both FoxP3-positive and negative HPV-specific CD4+CD25+ T cells was significantly correlated (p = 0.01). Interestingly, the detection of HPV-specific proliferation was associated with invasion depth (p = 0.020) but not with HLA type, tumor size nor LN status. Moreover, the detection of HPV-specific immunity was associated with an improved disease free survival (p = 0.04) in patients with deeply infiltrating tumors. In conclusion, HPV-specific proliferative T-cell response, comprising higher percentages of HPV-specific CD25+ and CD25+FoxP3-positive CD4+T cells, are more frequently detected in patients with deep infiltrating CxCa tumors and associated with an improved survival.

Abstract
We investigated the association of human leukocyte antigen (HLA) II (DRB1 and DQB1) alleles with susceptibility to human papillomavirus (HPV)-associated cervical precancer and cancer cases in a hospital-based case-control study in a northern Indian population. A total of 202 subjects, including 100 patients comprising 31 cervical precancer (cervical intraepithelial neoplasia [CIN] 2/3) and 69 invasive cervical cancer cases, and 102 healthy controls participated in the study. Both patients and controls were screened for HPV infection using a polymerase chain reaction (PCR-based approach. Low-resolution PCR-sequence specific priming (PCR-SSP) was used to genotype HLA II (DRB1 and DQB1). Our results demonstrate that the DRB1*15 allele/DRB1*15-DQB1*06 haplotype may have a predisposition for HPV infection (p(c) < 0.05) or cervical cancer/precancer (p(c) < 0.05) development, whereas the DRB1*04 allele/DRB1*04-DQB1*03 haplotype might exhibit susceptibility to cervical precancerous lesions (p(c) < 0.05). The DRB1*13 allele/DRB1*13-DQB1*06 haplotype was strongly protective against risk to HPV infection (p(c) < 0.002) as well as cervical cancer (p(c) 0.01). Therefore, we have demonstrated that HLA DR-DQ polymorphisms are involved in genetic susceptibility to cervical cancer or HPV infection in a northern Indian population.

Abstract
Cervical cancer is caused by persistent infection of oncogenic human papillomavirus (HPV). Most infected women clear the virus without developing cervical lesions and it is likely that immunological host factors affect susceptibility to cervical cancer. The impact of the human leukocyte antigen (HLA) locus on the risk of cervical cancer is established and several other genes involved in immunological pathways have been suggested as biologically plausible candidates. The aim of this study was to examine the potential role of polymorphisms in 4 candidate genes by analysis of 1,306 familial cervical cancer cases and 288 controls. The following genes and polymorphisms were studied: Chemokine receptor 2 (CCR-2) V64I; Interleukin 4 receptor alpha (IL-4R) I75V, S503P and Q576R; Interleukin 10 (IL-10) -592; and Fas ligand (FasL) -844. The CCR-2 64I variant was associated with decreased risk of cervical cancer; homozygote carriers of the 64I variant had an odds ratio of 0.31 (0.12-0.77). This association was detected in both carriers and noncarriers of the HLA DQB1*0602 cervical cancer risk allele. The IL-4R 75V variant was associated with increased risk of cervical tumors, cases homozygote for 75V had an odds ratio of 1.91 (1.27-2.86) with a tendency that the association was stronger in noncarriers of the DQB1*0602 allele. We did not find any association for IL-10 -592, or FasL -844, previously reported to be associated with cervical cancer in the Dutch and Chinese populations, respectively.

Abstract
The identification of high-risk human papillomavirus (HPV) types as a necessary cause of cervical cancer offers the prospect of effective primary prevention and the possibility of improving the efficiency of cervical screening programmes. However, for these opportunities to be realized, a more complete understanding of the natural history of HPV infection, and its relationship to the development of epithelial abnormalities of the cervix, is required. We discuss areas of uncertainty, and their possible effect on disease prevention strategies.

Abstract
Many studies have shown familial aggregation for cervical cancer, but they have been unable to distinguish between shared environmental and genetic effects. Full and half-siblings were identified from the nationwide Swedish Family-Cancer Database, including invasive and in situ cervical cancers in women up to age 70 years. Half-siblings were defined through a common father or mother. Standardized incidence ratios, adjusted for several variables, were calculated for proband-wise risks between full and half-siblings. The familial risk for full siblings was 1.84, compared with 1.40 for maternal and 1.27 for paternal half-siblings. These data were used to apportion familial risk for cervical tumors in full siblings into a heritable component, accounting for 64%, and an environmental component, accounting for 36% of the total risk. No evidence for gene-environment interactions was found. The intractable difficulty in separating cervical cancer causation will be an obstacle for a successful identification of susceptibility genes.

Abstract
Adeno-associated virus (AAV) can impair the replication of other viruses. Adeno-associated virus seroprevalences have been reported to be lower among women with cervical cancer. In-vitro, AAV can interfere with the production of human papillomavirus virions. Adeno-associated virus-2 DNA has also been detected in cervical cancer tissue, although not consistently. To evaluate the role of AAV infection in relation to invasive cervical cancer, we performed a nested case–control study within a retrospectively followed population-based cohort. A total of 104 women who developed invasive cervical cancer on average 5.6 years of follow-up (range: 0.5 months–26.2 years) and 104 matched control-women who did not develop cervical cancer during the same follow-up time were tested for AAV and human papillomavirus by polymerase chain reaction. At baseline, two (2%) case-women and three (3%) control-women were positive for AAV-2 DNA. At the time of cancer diagnosis, 12 (12%) case-women and 3 (3%) matched control-women were positive for AAV-2 DNA. Persisting AAV infection was not evident. In conclusion, AAV-2 DNA was present in a low proportion of cervical cancers and we found no evidence that the presence of AAV in cervical smears of healthy women would be associated with reduced risk of cervical cancer.

Abstract
Host genetic background seems to play a key role in cervical carcinogenesis as only a small subset of women infected with high-risk human papillomaviruses (HPVs) develop cervical cancer. The rate of cervical cancer in Vietnamese women is notably high. To explore the association of human leukocyte antigen (HLA)-DQB1 alleles, HPV infection, and cervical dysplasia in this population, cervical smears were obtained from 101 women attending the obstetrics and gynecology clinic of Da Nang General Hospital in Vietnam. Besides the Papanicolaou test, HPV and HLA-DQB1 genotyping were performed using cervical smear DNA. Additionally, a subset of 30 blood samples was used as the gold standard for HLA genotyping. HLA-DQB1 alleles showed no association with HPV infection status. However, a positive association with cervical dysplasia was found for HLA-DQB1*0302 (P= 0.0229, relative risk (RR) = 4.737) and HLA-DQB1*0601 (P= 0.0370, RR = 4.038), whereas HLA-DQB1*0301 (P= 0.0152, RR = 0.221) was found negatively associated. The low diversity of HLA-DQB1 alleles, wide spectrum of HPV genotypes, and high prevalence of HPV 16 and HPV 18 observed in the study population suggest a permissive/susceptible genetic background that deserves further research. Total concordance of HLA-DQB1 genotyping results between blood and cervical cells confirms the potential value of cervical smears as an effective tool for the development of cervical cancer biomarkers.

Natural killer (NK) cells are involved both in control of virus infections and in elimination of tumor cells. Killer immunoglobulin-like receptors (KIRs) either activate or inhibit NK cell-mediated cytolysis, protecting healthy cells from destruction while enabling killing of abnormal cells. To investigate whether KIR genes or genotypes are associated with cervical carcinogenesis, a nested case-control study of 65 case women with cervical intraepithelial neoplasia (CIN) diagnosed during a 6-year follow-up of 15,234 women and 150 control women from the same cohort that remained healthy was performed. More than 70 different genotypes were observed, and 33 of which had not been described previously. An A-genotype including KIR2DL1, KIR2DL2, KIR2DL3, KIR2DL4, KIR3DL1, KIR3DL2, KIR3DL3, and KIR2DS4 was associated with increased risk of CIN (OR 6.7; 95% CI 1.7-26.3), and KIR2DL5B*002 appeared to have an inverse association with disease (OR 0.5; 95% CI 0.5-2.9). There was no association of CIN with the number of activating KIR genes. There was also no association between KIR genes and type of human papilloma virus or with other CIN-related immune response genes. It was concluded that certain KIR genes and genotypes may associate with cervical neoplasia.

Abstract
BACKGROUND Cervical cancer represents a major health problem in Venezuela as well as in other Latin American countries. High-risk human papillomavirus (HR-HPV) infection is known as the major risk factor of cervical cancer. However, whether or not a HR-HPV-infected woman progresses to cervical cancer may depend on the immune system effectors induced by viral antigens presented by her specific human leukocyte antigens (HLA) alleles. The role of the HLA system in presenting peptides to antigen-specific T-cells may be critical for genetic susceptibility and genetic resistance to cervical carcinoma. OBJECTIVE We aimed to investigate the relationship between HLA-DQB1, HPV infection, and cervical cancer in Venezuelan women. METHODS Blood samples and cervical swabs were obtained from 36 patients and 79 healthy controls; additional cervical biopsies were obtained from all the patients. HPV DNA was detected by PCR and HLA-DQB1 genotyping was performed using a PCR-SSP protocol. RESULTS.: A positive association with cervical cancer was observed for HLA-DQB1*0201-0202 and *0402 alleles, however after Bonferroni correction only HLA-DQB1*0402 remained statistically significant (P value = 0.004, RR = 5.067). CONCLUSION This is the first report of HLA-DQB1 alleles associated with cervical carcinoma in Venezuelan women. Larger studies are needed to assess whether these HLA-DQB1*0201-0202 and *0402 alleles have a direct effect on disease susceptibility.

Abstract
Human papillomavirus (HPV) infection is the most important risk factor for development of cervical carcinoma. Carriers of certain HLA class II alleles, e.g., DRB1*1501 and DQB1*0602, are more prone to HPV 16 infection and cervical carcinoma, whereas other alleles, e.g., DRB1*1301 and DQB1*0603, render carriers less susceptible to the disease. In our study comprising 484 cases and 601 controls, we examine the effect of HLA class II alleles on viral load of the oncogenic types HPV 18/45 and HPV 31 and risk of developing cervical carcinoma in situ. We find that carriers of the commonly reported protective DRB1*1301 and DQB1*0603 alleles have lower HPV 18/45 load compared to noncarriers and a lower risk of developing HPV 18/45-positive cervical carcinoma. This provides further evidence that the HLA class II-mediated immune response to HPV is important for controlling viral load and outcome of an infection.

Abstract
Associations of human leukocyte antigen DR2 (HLA-DR2) and HLA-B7 with presumed ocular histoplasmosis syndrome (POHS) in the United States has been previously described. However, these associations were determined by means of low-resolution, complement-dependent cytotoxicity assays for HLA-A, HLA-B, and HLA-DR molecules. To determine whether POHS is associated with other HLA alleles within the HLA-A, HLA-B, HLA-DR, and HLA-DQ loci, we performed a case control study of 34 patients diagnosed with macular choroidal neovascular membrane secondary to POHS and 45 healthy control individuals. Peripheral blood-derived DNA from the study patients was typed for HLA genes by means of sequence-specific primers that gave low-medium allele resolution. Significant associations were observed between HLA-B7 (X2 = 14.30, pc = 0.004, relative risk = 8.23), HLA-DR15 (X2 = 29.08, pc = 0.000001, relative risk = 27.50), and HLA-DQ6 (X2 = 23.09, pc = 0.00001, relative risk = 27.43) and POHS. Because there are strong linkage disequilibria between HLA-DR15 (a subtype of HLA-DR2) and HLA-B7 as well as HLA-DQ6, the significantly higher association of HLA-DR15 and HLA-DQ6 with POHS as compared to HLA-B7 suggests that the former alleles mediate susceptibility to the disease. In conclusion, there is a significant association between the HLA-DR15/HLA-DQ6 haplotype and development of choroidal neovascular lesions in POHS.

Abstract
Screening programmes for cervical cancer using the current test--the Pap smear--have markedly reduced the incidence of the disease. However, an individual Pap test is of limited sensitivity and is difficult and expensive to perform. Increased understanding of the molecular pathogenesis of cervical cancer indicates that new approaches to screening might offer increased accuracy, affordability and the potential for automation. Such approaches exemplify how improved understanding of the biology of neoplasia might be translated into clinical benefit.
