Abstract
Renal cell carcinoma (RCC) accounts for the majority of cancer-related deaths worldwide. Overexpression of CD70 has been linked to advanced stages of RCC. Therefore, this study aims to develop a multiepitope vaccine targeting the overexpressed CD70 using immunoinformatics techniques. In this investigation, in silico multiepitope vaccines were constructed by linking specific CD70 protein epitopes for helper T lymphocytes and CD8+ T lymphocytes. To enhance immunogenicity, sequences of cell-penetrating peptide (CPP), penetratin (pAntp), along with the entire sequence of tumor necrosis factor-α (TNF-α), were attached to the N-terminal and C-terminal of the CD70 epitopes. Computational assessments were performed on these chimeric vaccines for antigenicity, allergenicity, peptide toxicity, population coverage, and physicochemical properties. Furthermore, refined 3D constructs were subjected to a range of analyses, encompassing structural B-cell epitope prediction and molecular docking. The chosen vaccine construct underwent diverse assessments such as molecular dynamics simulation, immune response simulation, and in silico cloning. All vaccines comprised antigenic, nontoxic, and nonallergenic epitopes, ensuring extensive global population coverage. The vaccine constructs demonstrated favorable physicochemical characteristics. The binding affinity of chimeric vaccines to the TNF receptor remained relatively stable, influenced by the alignment of vaccine components. Molecular docking and dynamics analyses predicted stable interactions between CD70-CPP-TNF and the TNF receptor, indicating potential efficacy. In silico codon optimization and cloning of the vaccine nucleic acid sequence were accomplished using the pET28a plasmid. Furthermore, this vaccine displayed the capacity to modulate humoral and cellular immune responses. Overall, the results suggest therapeutic potential for the chimeric CD70-CPP-TNF vaccine against RCC. However, validation through in vitro and in vivo experiments is necessary. This trial is registered with NCT04696731 and NCT04046445.

Abstract
Background HERV-K env is associated with several neurological disorders, including MS. Clinical studies have demonstrated a plausible interaction between HERV-K env and other MS risk factors. The present study aimed to investigate the possible association between HERV-K18 env and TGF-β. We further assessed the in vitro effect of EBV infection on HERV-K18 env expression in the presence and absence of vitamin D in MS patients. Methods PBMCs from 20 MS patients and 20 healthy controls were infected with the B95.8 EBV, seeded into 24-well plates and incubated in the presence or absence of 100 nM of 1,25(OH)D3. The expression levels of HERV-K18 env and TGF-β were measured using real-time PCR. Results While the expression level of HERV-K18 env was significantly higher in MS patients than the healthy controls, this trend for TGF-β was significantly reverse. Interestingly, an inverse correlation was found between HERV-K18 env and TGF-β expression in MS patients, although the in vitro stimulation of PBMCs with EBV and vitamin D showed no significant differences in terms of HERV-K18 expression. Conclusion Our findings highlight the potential role of HERV-K18 env in MS patients.

Abstract
Background West Nile virus (WNV) is a mosquito-borne virus that causes a febrile disease and may cause a fatal neurological illness in humans. We aimed to investigate the geographic distribution of Culicinae mosquitoes and their possible infection with WNV in Hormozgan Province, southern Iran. Methods Field studies were carried out from June 2017 to May 2019. Different mosquito sampling methods were used monthly to collect mosquitoes from 22 sites. The Real-Time PCR technique was used to detect the virus infection in the mosquitoes. Results Overall, 6165 mosquitoes were caught. The species were Culex theileri (33.25%), Cx. pipiens (20.45%), Cx. quinquefasciatus (10.51%), Aedes caspius (6.33%), Cx. tritaeniorhynchus (5.82%), Ae. vexans (4.10%), Cx. sinaiticus (3.62%), Cx. antennatus (3.29%), Culiseta longiareolata (2.81%), Cx. perexiguus (2.03%), Cs. subochrea (1.95%), Cx. mimeticus (1.49%), Cx. pusillus (1.38%), Cx. univittatus (1.27%), Cx. modestus (1.14%), and Cx. sitiens (0.57%). The molecular detection of virus infection in mosquitoes found to be negative for WNV. Conclusion The presence of many species of mosquito vectors and high population traffic increase the risk of disease transmission is very high. Therefore, the way to restrict WNV infection factors is increasing the knowledge for personal protection measures to prevent mosquito bites.

Abstract
Skin rash is one of the most common complications during childhood. Viral agents play an essential role in the development of such symptoms. Present study aims to determine the prevalence and genetic variability of HHV-6 & HHV-7 infections and their subtypes in children under five years of age with skin rash and negative for rubella and measles. We used serum and throat swap samples from 196 children with skin rash and fever. ELISA and IFA tests were performed to detect antibodies against HHV6/7. Sequencing was performed using Sanger sequencing, and BioEdit and MEGA10 software were used for sequence analysis. According to the results, 66% and 40% of cases were positive for HHV-6 IgM and HHV-7 IgM, respectively. According to the molecular analysis, HHV-6 Nested-PCR was positive in 18% of cases, however, HHV-7 Nested-PCR was positive in 7.7% of cases. On the other hand, HHV-6 IgG and HHV-7 IgG were positive in 91% and 55% of study cases, respectively. For HHV-6, we found some genetic variabilities resulting in antigenic changes compared to reference strains. HHV-7 isolates showed no genetic differentiation and had a stable gene sequence. Based on the results, the detection of some cases of HHV6/7 primary infection and the presence of specific symptoms of roseola in the study population needs continuous evaluation of HHV6/7 frequency and distribution, also genetic variabilities of HHV6. This can pave the way for investigating HHV6 immune evasion and vaccine research and studying the relationship between viral genetic variations and other factors like disease severity. Furthermore, it is necessary to determine the relation between HHV6 genetic changes and latent infection to be considered in possible future vaccines and antiviral drug development.

Abstract
Post-transplant human cytomegalovirus (HCMV) viremia has been linked to adverse "indirect effects" among transplant patients. HCMV-created immunomodulatory mechanisms could be associated with the indirect effects. OBJECTIVE In the present study, the RNA-Seq whole transcriptome of renal transplant (RT) patients was analyzed to seek the underlying pathobiologic pathways associated with the long-term indirect effects of HCMV. METHODS To investigate the activated biological pathways in HCMV infection, total RNA was extracted from PBMCs of 2 RT patients with active HCMV and 2 RT patients without infection and then were sequenced using RNA-Seq. The resulted raw data were analyzed by conventional RNA-Seq software to determine the Differentially Expressed Genes (DEGs). Afterward, Gene Ontology (GO) and pathway enrichment analyses were conducted to determine the enriched pathways and biological processes by DEGs. Eventually, the relative expressions of some significant genes were validated in the twenty external RT patients. RESULT The analysis of RNA-Seq data related to RT patients with HCMV active viremia led to the identification of 140 up-regulated and 100 down-regulated DEGs. KEGG pathway analysis revealed the enrichment of DEGs in IL18 signaling, AGE-RAGE signaling pathway in diabetic complications, signaling by GPCR, Platelet activation, signaling and aggregation, Estrogen signaling pathway and signaling by Wnt due to HCMV infection. The expression levels of six genes involved in enriched pathways including F3, PTX3, ADRA2B, GNG11, GP9, HBEGF were then verified using RT-qPCR. The results were in consistent with RNA-Seq resultsoutcomes. CONCLUSION This study specifies some pathobiological pathways which are activated in HCMV active infection and could be linked to the adverse indirect effects caused by HCMV infection in transplant patients.

Abstract
Immune reconstitution after hematopoietic stem cell transplantation (HSCT) with a conditioning regimen has appeared to be a promising treatment for autoimmune diseases and hematologic malignancies. This study aimed to assess the T cell receptor (TCR) repertoire diversity in CD4+ cells of patients with hematological malignancies who received allogeneic or autologous HSCT.
The diversity of the TCR repertoire was evaluated in 13 patients with hematologic malignancies before and four months after HSCT. Amino acid changes in the 25 Vβ families were evaluated using Spectratyping and data were presented as Hamming distance (HD). HD more than 20% was considered a change in TCR repertoire after HSCT.
The mean HD was significantly changed after transplantation in all Vβ gene families, with most amino acid changes in p4 and p22 families. There was a strong negative correlation between the HD as the index of TCR repertoire and age (r=−0.62,). The results revealed no association between HD mean and parameters such as sex, disease, conditioning regimen, and type of transplantation.
Our data revealed that commonly used conditioning regimens in Iran could successfully cause TCR repertoire diversity in patients with hematologic malignancies in the short term. The amount of change in TCR repertoire was inversely correlated with the increasing age of patients.

Abstract
Background and Objectives Parvovirus B19 (B19V) is usually transmitted through respiratory tract, but can also be received through blood transfusion. This study evaluated the seroprevalence, DNA existence, and circulating genotypes of B19V in hemophilia patients. Materials and Methods Serum samples of cases and controls were analyzed for B19V using ELISA and real-time PCR. Finally, obtained sequences were used for genotyping. Results Among cases, 3% were anti-B19V IgM positive and 47% were anti-B19V IgG positive and B19V DNA was detected in 16% of them. However, among controls, 38% were anti-B19V IgG positive (P>0.05) and 5% were B19V DNA positive (P= 0.019). Also ∼13% of cases were positive and all of controls were negative for IgG avidity test (P= 0.029). Viral load in case group was higher than control group (P = 0.037). Conclusion Since hemophilia patients receive large amounts of blood factors, prevalence of B19V in these patients might be higher than normal subjects.

Abstract
γδ T cells are rare lymphocytes with cogent impact on immune responses. These cells are one of the earliest cells to be recruited in the sites of infection or tumors and play a critical role in coordinating innate and adaptive immune responses. The anti-tumor activity of γδ T cells have been numerously reported; nonetheless, there is controversy among published studies regarding their anti-tumor vs pro-tumor effect- especially in pancreatic cancer. A myriad of studies has confirmed that activated γδ T cells can potently lyse a broad variety of solid tumors and leukemia/lymphoma cells and produce an array of cytokines; however, early γδ T cell-based clinical trials did not lead to optimal efficacy, despite acceptable safety. Depending on the local micromilieu, γδ T cells can differentiate into tumor promoting or suppressing cells such as Th1-, Th2-, or Th17-like cells and produce prototypical cytokines such as interferon-γ (IFNγ) and interleukin (IL)-4/-10, IL-9, or IL-17. In an abstruse tumor such as pancreatic cancer- also known as immunologically cold tumor- γδ T cells are more likely to switch to their immunosuppressive phenotype. In this review we will adduce the accumulated knowledge on these two controversial aspects of γδ T cells in cancers- with a focus on solid tumors and pancreatic cancer. In addition, we propose strategies for enhancing the anti-tumor function of γδ T cells in cancers and discuss the potential future directions.

Abstract
Biofilm formation and antibiotic resistance are the most important ways in which water bacteria such as Pseudomonas aeruginosa are protected against antibacterial agents. The aim of this study was to develop a rapid and cost-effective laboratory method for modeling and optimizing chlorine disinfection conditions. Critical factors (disinfection type, concentration, contact time and pH) were tested on bactericidal effect, inhibition of biofilm formation (IBF) and antibiotic susceptibility (AS) of P. aeruginosa. The central composite face-centered (CCF) design was applied to model the effect of disinfection process on the IBF and AS. The results showed that the IBF response was more affected by the strain type of P. aeruginosa and the type of disinfectant, which may be due to previous species growth conditions of the standard strain and greater durability of CAT in water. Optimization of factors affecting disinfection had a significant effect on the planktonic form, but was not effective in removing the biofilm of P. aeruginosa. Furthermore, the concentration of NaOCl and CAT was more effective than pH on planktonic and biofilm cells inactivation. The model of AS was weaker than other models due to limited contact time and use of high concentrations of disinfectant. The use of chlorine compounds based on the recommended levels in water does not prevent the formation of P. aeruginosa biofilm. According to the optimization findings, although increasing the contact time and concentration of the disinfectant increases the bactericidal effect of chlorine, it can also increase the resistance of P. aeruginosa to some antibiotics.

Immune system in healthy individuals is capable of controlling HCMV infection; however, HCMV can be life-threatening for immunocompromised individuals, such as transplant recipients. Both innate and adaptive immune systems are critically involved in the HCMV infection. Recent studies have indicated that regulatory immune cells which play essential roles in maintaining a healthy immune environment are closely related to immune response in HCMV infection. However, the exact role of regulatory immune cells in immune regulation and homoeostasis during the battle between HCMV and host still requires further research. In this review, we highlight the protective and pathological roles of regulatory immune cells in HCMV infection following hematopoietic stem cell transplantation (HSCT).

Abstract
INTRODUCTION Chronic fatigue syndrome (CFS) is a neurological disease that is accompanied by excessive fatigue or tiredness. There are several reports confirming the association between human herpesvirus 6 (HHV-6) infection and CFS illness. This systematic review and meta-analysis was performed to integrate the information of published studies with regard to this association until May 2021. METHODS The literature search was based on keywords including "chronic fatigue syndrome and HHV 6," "chronic fatigue syndrome and HHV-6," "chronic fatigue syndrome and HHV6," "chronic fatigue syndrome and Herpes virus 6," and "chronic fatigue syndrome and Herpesvirus6" in MEDLINE (PubMed), Web of Science, and EMBASE. RESULTS The literature search identified 17 studies to be included in the systematic review and 11 studies in meta-analysis. The symmetry funnel plot and Egger's test (p value = 0.2) identified no publication bias among studies. Moreover, the low level of I2 revealed homogeneity across studies. DISCUSSION In conclusion, the association between the HHV-6 infection and CFS incidence was substantiated. However, the results of this study also suggest that further comprehensive studies are needed to solidify the association between HHV-6 and CFS. Future studies should consider additional factors that may have affected the significance of such a correlation.

Abstract
Stenotrophomonas maltophilia exhibits wide spectrum of fluoroquinolone resistance using different mechanisms as multidrug efflux pumps and Smqnr alleles. Here, the role of smeDEF, smeVWX efflux genes and contribution of Smqnr alleles in the development of fluoroquinolone resistance was assessed. Ciprofloxacin, levofloxacin and moxifloxacin resistance were found in 10.9%, 3.5%, and 1.6% of isolates, respectively. More than four-fold differences in ciprofloxacin MICs were detected in the presence of reserpine and smeD, F, V expression was significantly associated with ciprofloxacin resistance (p = 0.017 for smeD, 0.003 for smeF, and 0.001 for smeV). Smqnr gene was found in 52% of the ciprofloxacin-resistant isolates and Smqnr8 was the most common allele detected. Fluoroquinolone resistance in S. maltophilia clinical isolates was significantly associated with active efflux pumps. There was no correlation between the Smqnr alleles and ciprofloxacin resistance; however, contribution of the Smqnr genes in low-level levofloxacin resistance was revealed.

Abstract
This study aimed to evaluate the prevalence of human rhinoviruses (HRVs) and the emergence of enterovirus D68 (EV-D68) in children. A total of 322 nasopharyngeal swab samples were provided from children with an initial diagnosis of upper and lower respiratory tract infections. A total of 34 and 70 cases were positive for EV-D68 and HRV, respectively. The phylogenetic analysis revealed that the clades A and B are the prevalent genotypes for EV-D68 and the HRV-positive samples belong to three types including HRV-A, HRV-B, and HRV-C. The results showed that EV-D68 and HRV-C are circulating in Iran especially in the winter.

Abstract
Human immunodeficiency virus type 1 (HIV-1), the virus that causes AIDS (acquired immunodeficiency syndrome), is a major global public health issue. Although the advent of combined antiretroviral therapy (ART) has made significant progress in inhibiting HIV replication in patients, HIV-infected cells remain the principal cellular reservoir of HIV, this allows HIV to rebound immediately upon stopping ART, which is considered the major obstacle to curing HIV infection. Chimeric antigen receptor (CAR) cell therapy has provided new opportunities for HIV treatment. Engineering T cells or hematopoietic stem cells (HSCs) to generate CAR T cells is a rapidly growing approach to develop an efficient immune cell to fight HIV. Herein, we review preclinical and clinical data available for the development of CAR T cells. Further, the advantages and disadvantages of clinical application of anti-HIV CAR T cells will be discussed.

Abstract
Background: West Nile Virus, a mosquito-borne flavivirus, causes a variety of symptoms in human, from asymptomatic infection to neuroinvasive disease. Several studies have been conducted on the seroprevalence of WNV infection in different areas from Iran. This study was performed to find the presence of antiviral antibodies in human serum among some high risk population and awareness of health care staff about symptom of the WNV infection. Methods: Study performed in five geographical districts based on high population of immigrant and domestic birds and prevalence of the antiviral antibodies in horses which was reported previously. Totally 150 human blood samples were collected during 2018. The samples collected from patients referred to the clinics. The ELISA method used to detect IgG and IgM antibody against WNV. Logistic regression models used to analyze the effect of sex, age, keeping birds and urban/rural residence on the risk of infection. The awareness of health care staff about symptom of infection surveyed. Results: From all blood donors, 41 samples (27.33%) showed positive to IgG antibody. From which 56.10% were males and remaining females. None of the mentioned factors had a significant relationship. Health care staff had less attention to the infection. Conclusion: Although the prevalence of antibodies was relatively high, due to the similarity to other viral diseases, health care staff had less attention to the disease. The study showed that people in these areas have been exposed to the virus. Further research activities are recommended for control of this arbovirus.

Abstract
INTRODUCTION H1N1 influenza virus, as an indoor/outdoor pathogen in air, can cause the flu-like illness and respiratory complication. The aim of this study was to evaluate the H1N1 influenza virus replication in pancreas and investigate the immune response against infected pancreas. MATERIAL AND METHODS First, mouse pancreas cell line was infected by H1N1 influenza A virus using intranasally and intravenously infection methods, and then the pancreas tissue was collected and pathology experiment was carried out. Next, the protein and genome of influenza virus were detected using immunocytochemistry and real-time PCR, respectively. In addition, serum cytokines and serum lipase were investigated using ELISA. RESULT The in-vitro results proved that the mouse pancreatic cell line can support influenza virus replication. The result also proved that influenza virus is capable to infect pancreas and induce pancreas damage. Further, the immune response in mice with infected pancreas exhibited a completely different pattern with that of mice infected through intranasal method. CONCLUSION It can be concluded that influenza virus can infect pancreas and change the influenza disease pathway, which might result in a pancreatic injury.

Abstract
Based on available metabolomic studies, influenza infection affects a variety of cellular metabolic pathways to ensure an optimal environment for its replication and production of viral particles. Following infection, glucose uptake and aerobic glycolysis increase in infected cells continually, which results in higher glucose consumption. The pentose phosphate shunt, as another glucose-consuming pathway, is enhanced by influenza infection to help produce more nucleotides, especially ATP. Regarding lipid species, following infection, levels of triglycerides, phospholipids, and several lipid derivatives undergo perturbations, some of which are associated with inflammatory responses. Also, mitochondrial fatty acid β-oxidation decreases significantly simultaneously with an increase in biosynthesis of fatty acids and membrane lipids. Moreover, essential amino acids are demonstrated to decline in infected tissues due to the production of large amounts of viral and cellular proteins. Immune responses against influenza infection, on the other hand, could significantly affect metabolic pathways. Mainly, interferon (IFN) production following viral infection affects cell function via alteration in amino acid synthesis, membrane composition, and lipid metabolism. Understanding metabolic alterations required for influenza virus replication has revealed novel therapeutic methods based on targeted inhibition of these cellular metabolic pathways.

Abstract
Human influenza A viruses (IAVs) cause global pandemics and epidemics, which remains a nonignorable serious concern for public health worldwide. To combat the surge of viral outbreaks, new treatments are urgently needed. Here, we design a new vaccine based on virus-like particles (VLPs) and show how intranasal administration of this vaccine triggers protective immunity, which can be exploited for the development of new therapies. H1N1 VLPs were produced in baculovirus vectors and were injected into BALB/c mice by the intramuscular (IM) or intranasal (IN) route. We found that there were significantly higher inflammatory cell and lymphocyte concentrations in bronchoalveolar lavage samples and the lungs of IN immunized mice; however, the IM group had little signs of inflammatory responses. On the basis of our results, immunization with H1N1 influenza VLP elicited a strong T cell immunity in BALB/c mice. Despite T cell immunity amplification after both IN and IM vaccination methods in mice, IN-induced T cell responses were significantly more intense than IM-induced responses, and this was likely related to an increased number of both CD11bhigh and CD103+ dendritic cells in mice lungs after IN administration of VLP. Furthermore, evaluation of interleukin-4 and interferon gamma cytokines along with several chemokine receptors showed that VLP vaccination via IN and IM routes leads to a greater CD4+ Th1 and Th2 response, respectively. Our findings indicated that VLPs represent a potential strategy for the development of an effective influenza vaccine; however, employing relevant routes for vaccination can be another important part of the universal influenza vaccine puzzle.

Abstract
Lack of culturability in the viable but non-culturable (VBNC) bacteria and the ability to regain infectivity in favourable conditions is one of the new challenges of public health providers for Pseudomonas aeruginosa monitoring in environmental samples. Propidium monoazide quantitative polymerase chain reaction (PMA-qPCR) is one of the promising methods for timely detection of VBNC pathogens in environmental samples. We developed and used a method for the first time to detection of VBNC P. aeruginosa in swimming pool water samples using a membrane filter (MF). Moreover, the dominant model of the distribution of colonies on the MF and the effect of the culture medium and MF type on colony recovery by MF were evaluated. Swimming pool samples were subjected to conventional culture-based, qPCR and PMA-qPCR methods and the results were compared for the presence of VBNC P. aeruginosa in the samples. The positivity rate was 21% and 75% for P. aeruginosa in water samples as confirmed by standard culture-based and qPCR methods, respectively. Furthermore, of 24 samples, 9 (37.5%) were positive for VBNC P. aeruginosa. The developed qPCR/PMA-qPCR assay can detect the VBNC bacteria directly from aquatic samples and may result in better monitoring of recreational waters.

Abstract
Rapid and species-specific detection, and virulence evaluation of opportunistic pathogens such as Pseudomonas aeruginosa, are issues that increasingly has attracted the attention of public health authorities. A set of primers and hydrolysis probe was designed based on one of the P. aeruginosa housekeeping genes, gyrB, and its specificity and sensitivity was evaluated by TaqMan qPCR methods. The end point PCR and SYBR Green qPCR were used as control methods. Furthermore, multiplex RT-qPCRs were developed for gyrB as reference and four virulence genes, including lasB, lasR, rhlR and toxA. Totally, 40 environmental samples, two clinical isolates from CF patients, two standard strains of P. aeruginosa, and 15 non-target reference strains were used to test the sensitivity and specificity of qPCR assays. In silico and in vitro cross-species testing confirmed the high specificity and low cross-species amplification of the designed gyrB418F/gyrB490R/gyrB444P. The sensitivity of both TaqMan and SYBR Green qPCRs was 100% for all target P. aeruginosa, and the detected count of bacteria was below ten genomic equivalents. The lowest M value obtained from gene-stability measurement was 0.19 that confirmed the suitability of gyrB as the reference gene for RT-qPCR. The developed qPCRs have enough detection power for identification of P. aeruginosa in environmental samples including clean and recreational water, treated and untreated sewage and soil. The short amplicon length of our designed primers and probes, alongside with a low M value, make it as a proper methodology for RT-qPCR in virulence genes expression assessment.

Abstract
Aim: Since HER2 targeted therapies have shown clinical benefit in breast cancer, in the present study recombinant baculovirus (BV) displaying anti-HER2 single-chain variable domain fragment (scFv) expressing Apoptin was generated. Methods: The binding specificity and surface display of anti-HER2 scFv were evaluated using enzyme-linked immunosorbent assay (ELISA) and electron microscopy, respectively. The targeting properties and cytotoxic effect on breast cancer cells determined by fluorescence microscopy and MTT assays. Results: The results demonstrated that recombinant BV could specifically bind to HER2-overexpressing SK-BR-3 cells but not to the HER2 negative MCF-7 cells and reduced the viability of SK-BR-3 cells by expressing Apoptin. Conclusion: These results suggest that the antitumor effect of Apoptin in combination with HER2 targeting of this recombinant BV makes it a promising vector in targeted cancer therapy.

Abstract
Regulatory T cells (Tregs) are critical for maintaining immune response and enhancing their differentiation has therapeutic implications for autoimmune diseases. In this study, we investigated the effects of thymol a well-known monoterpene from Thyme on differentiation and function of Tregs. In vitro generation of Tregs from purified naïve CD4+CD25- T cells in the presence of thymol was carried out. Suppressor activity of generated Tregs was examined by changes in the proliferation of CFSE-labeled conventional T cells. Thymol promotes differentiation of naïve CD4+CD25- T cells to CD4+CD25+Foxp3+ Tregs [66.9-71.8% vs. control (47%)] and increased intensity of Foxp3 expression on Tregs (p < 0.01). In functional assay, an increased immune suppression by thymol-induced Tregs (≈2.5 times of untreated Tregs) was detected. For in vivo study, thymol was intraperitoneally administered to ovalbumin (Ova)-immunized mice. Flow cytometry assessment of spleens from thymol-treated Ova-immunized mice showed increased number of CD4+ Foxp3+ Tregs (>8%, p < 0.01(and decreased levels of CD4+T-bet+ Th1 and CD4+RORγt+ Th17 cells resulted in significant decreased Th1/Treg and Th17/Treg ratios. In ex vivo Ova challenge of splenocytes from thymol-treated Ova-immunized mice, similarly higher levels of CD4+ Foxp3+ Tregs, and also elevated TGF-β expression in CD4+Foxp3+ population (48.1% vs. 18.9% in untreated Ova-immunized group) and reduced IFN-γ-producing CD4+T-bet+ T cells and IL-17-producing CD4+RORγt+ T cells were detected. This led to marked decreased ratios of IFNγ/TGF-β and IL-17/TGF-β expressions. In conclusion, this study revealed thymol as a compound with enhancing effects on Treg differentiation and function, which may have potential benefits in treatment of immune-mediated diseases with Th1/Th17 over-activation.

Abstract
CD4+ T cell subsets including regulatory T cells (Tregs), Th1 and Th17 are critical for control and development of inflammation and autoimmunity. We investigated the in vitro and in vivo effects of silymarin, a well-known herbal medicine on differentiation and function of Tregs and Th1 and Th17 responses. For in vitro study, mice splenocytes treated with 20-30 μg/ml silymarin were evaluated for gene expressions of specific transcription factors and cytokines of CD4+ T cell subsets using real-time PCR. Induction of Treg cell development in the presence of silymarin was performed on isolated naïve CD4+ T cells. Effect of silymarin-induced Tregs on T cell suppression was determined by CFSE labeling method. Results of this part showed that silymarin significantly decreased IFNγ, RORγt and IL-17 gene expressions and upregulated Foxp3, TGF-β and IL-10 mRNA. More silymarin-enhanced naïve CD4+ T cells differentiated to Tregs (67%) than the control (47%). Silymarin-induced Tregs reduced proliferation of naïve activated T cells (<50%). For in vivo study, mice were immunized with ovalbumin (Ova) on days 1 and 14. Silymarin (100 mg/Kg) was intraperitoneally administered two days before the first Ova challenge followed by on every day for two weeks. Splenocytes were then isolated for assessment of CD4+ T cell subsets and ex vivo analysis using flow cytometry. Treatment of Ova-immunized mice with silymarin increased Tregs (11.24 ± 1.2%, p < 0.01(but decreased Th1 (1.72 ± 0.4%, p < 0.001) and Th17 (1.07 ± 0.04%, p < 0.001) cells. Ex vivo Ova challenge of splenocytes from Ova-immunized mice treated with silymarin decreased proliferation of splenocytes, IFNγ (2.76% of control) and IL-17 (<8%) along with increased TGF-β (59.7%) expressions in CD4+T-bet+, CD4+RORγt+ and CD4+Foxp3+ T cells, respectively. In conclusion, silymarin promoted Treg differentiation and function and decreased Th1 and Th17 cells. Silymarin may differentially regulate CD4+ T cell responses which can provide potential benefits for its use as treatment of immune-related diseases. Graphical abstract ᅟ.

Abstract
The alarming rise of morbidity and mortality caused by influenza pandemics and epidemics has drawn attention worldwide since the last few decades. This life-threatening problem necessitates the development of a safe and effective vaccine to protect against incoming pandemics. The currently available flu vaccines rely on inactivated viral particles, M2e-based vaccine, live attenuated influenza vaccine (LAIV) and virus like particle (VLP). While inactivated vaccines can only induce systemic humoral responses, LAIV and VLP vaccines stimulate both humoral and cellular immune responses. Yet, these vaccines have limited protection against newly emerging viral strains. These strains, however, can be targeted by universal vaccines consisting of conserved viral proteins such as M2e and capable of inducing cross-reactive immune response. The lack of viral genome in VLP and M2e-based vaccines addresses safety concern associated with existing attenuated vaccines. With the emergence of new recombinant viral strains each year, additional effort towards developing improved universal vaccine is warranted. Besides various types of vaccines, microRNA and exosome-based vaccines have been emerged as new types of influenza vaccines which are associated with new and effective properties. Hence, development of a new generation of vaccines could contribute to better treatment of influenza.

Abstract
Valproic acid (VPA) is an inhibitor of histone deacetylases (HDACs) that can regulate differentiation and proliferation of stem cells by epigenetic mechanisms. We investigated VPA induced histone H3 and H4 acetylation in adipose derived stem cells (ADSCs) transdifferentiated into neuron-like cells (NLCs). Rat ADSCs were transdifferentiated into neural stem cells (NSCs) that had been generated from neurospheres. The NSCs were differentiated into NLCs by induction with different concentrations of VPA at 24, 48 and 72 h. The NLCs were evaluated using anti-H3 and -H4 antibodies, and ADSCs, NSCs and NLCs were evaluated using immunofluorescence. The ADSCs were immunoreactive to CD90 and CD49d, but not to CD45 and CD31. Both the neurospheres and NSCs were immunostained with nestin and neurofilament 68. The neurospheres expressed Musashi1, Sox2 and Neu N genes as determined by RT-PCR. Our dose-response study indicated that the optimal concentration of VPA was 1 mM at 72 h. Histone acetylation levels of H3 and H4 immunostaining intensities in NLCs were significantly greater than for ADSCs and NSCs. VPA alters H4 and H3 acetylation immunoreactivities of ADSCs transdifferentiated into NLCs.

Abstract
Sand fly fever is caused by Naples (SFNV) and Sicilian viruses (SFSV) and the closely related Toscana virus of the Phlebovirus genus in the family Bunyaviridae, and transmitted by Phlebotomine sand flies. Phlebotomus papatasi Scopoli, 1786 is known as the main vector of the disease. This study aimed to investigate the distribution of Phlebotomine sand flies as vector of sand fly fever viruses, and the effects of some environmental variables on their potential dispersion to new areas in some provinces of Iran. Sand flies were collected during their active season in the region using CDC light traps. Ecological parameters were recorded for each collection site. Arc GIS 10.3 software was used for data analysis and mapping the distribution of sand flies. Sampling in the study areas was carried out in six different climatic zones. Seventeen sand fly species were collected including eight species of genus Phlebotomus and nine species of genus Sergentomyia. The Medium Semi-Arid climatic zone had the highest species diversity. Fourteen species of sand flies were collected at altitude between 2 and 325 m, and seven species were collected between 326 and 1380 m above sea level. There was significant correlation between sand fly density and all tested environmental variables. Phlebotominae sand flies have wide distribution in Iran and have a major public health concern in the country. P. papatasi and Sergentomyia sintoni Pringle, 1933 prefers hot summers and rainfall. This poses a threat of transmission of sand fly fever caused by SFSV and SFNV across the country.

Abstract
Viral infections have been considered as possible destructive factors that influence male fertility. The aim of this study was to determine the prevalence of human herpes viruses 1-5 (HHV1-5), adeno associated virus (AAV) and human papilloma virus (HPV) in semen and whether these influence semen quality. DNA extraction was performed using phenol-chloroform protocol, then three different nested-PCRs were done to detect HHV1-5, AAV and HPV DNAs in the semen samples. Of 145 samples, 66 (45.5%) were positive at least for one of the viruses. The genome detection rate of HSV1/2, VZV, EBV, HCMV, AAV and HPV were zero, 2.8%, zero, 1.4%, 27.6% and 19.3%, respectively. Of 66 positive samples for these viruses, 6 (4.1% of all samples) were positive for two viruses simultaneously. Here no association was found between variations in semen parameters related to fertility and detection of VZV, HCMV, AAV and HPV DNA in semen samples. It should be noted that the prevalence of different viruses in semen, and their relevance to male infertility, differs significantly due to the genome extraction and amplification methods or due to a real variation between study populations and geographical regions.

Abstract
In this study, we evaluated solid sorbents for their ability to passively control indoor CO2 concentration in buildings or rooms with cyclic occupancy (eg, offices, bedrooms). Silica supported amines were identified as suitable candidates and systematically evaluated in the removal of CO2 from indoor air by equilibrium and dynamic techniques. In particular, sorbents with various amine loadings were synthesized using tetraethylenepentamine (TEPA), poly(ethyleneimine) (PEI) and a silane coupling agent 3-aminopropyltriethoxysilane (APS). TGA analysis indicates that TEPA impregnated silica not only displays a relatively high adsorption capacity when exposed to ppm level CO2 concentrations, but also is capable of desorbing the majority of CO2 by air flow (eg, by concentration gradient). In 10 L flow-through chamber experiments, TEPA-based sorbents reduced outlet CO2 by up to 5% at 50% RH and up to 93% of CO2 adsorbed over 8 hours was desorbed within 16 hours. In 8 m3 flow-through chamber experiments, 18 g of the sorbent powder spread over a 2 m2 area removed approximately 8% of CO2 injected. By extrapolating these results to real buildings, we estimate that meaningful reductions in the CO2 can be achieved, which may help reduce energy requirements for ventilation and/or improve air quality.

Abstract
We previously developed an influenza virus like particle with HA, M, and NA proteins using Bac-to-Bac expression system and SF9 cell line. To evaluate the immunogenicity of our construct, we assessed the humoral, cytokine induced by H1N1-VLP in BALB/c mice immunized intranasally and intramuscularly. Enzyme-linked immunosorbent assay and Relative quantitative real-time PCR were used to evaluate the antibody (IgG and IgA) and mRNA levels of IL-6, IL-4, IL-10 and IFN-g in PBMCs. Our results showed that VLP was capable of intranasal (I.N.) and intramuscular (I.M.) induction of serum IgG and IgA responses. Interestingly, I.N. route induced higher IgG and IgA titer than I.M. route, which was statistically significant. Moreover, mRNA levels of IL-6 (4.2-4.5 folds), IFN-g (5.5-5.7 folds), and the anti-inflammatory cytokine IL-10 (2.5-3 folds) and IL-4 (2.4-2.8 folds) were significantly elevated in mice immunized I.N. and I.M. with H1N1-VLP compared to the control group. Our findings indicated that a non-infectious genome-less VLP approach mimics parenteral virus with multiple viral antigens and epitopes that stimulate a diverse set of immune responses such as innate immunity, specific serum IgG antibody, cell-mediated immunity, and local antibodies.

Abstract
Regulatory T cells (Tregs) are important components of the immune system that modulate responses of other cells. These cells are involved in peripheral tolerance mechanisms, so defect in development and function of these cells can result in autoimmune disease. Increasing evidence supports the role of microRNAs-21 (miR-21) in the regulation of forkhead box P3 (Foxp3) expression in Tregs. We aimed to determine whether miR-21 transfection to naive CD4+ T cells can be useful in generation of iTregs in-vitro. We investigated in-vitro differentiation of miR-21-transfected naive CD4+ T cells to iTregs and compared these iTregs to cytokine-differentiated iTregs and control group. We showed that expression of Foxp3, transforming growth factor beta (TGF-β), and interleukin-10 (IL-10) are increased in iTregs generated after miR-21 transfection in comparison with cytokine-differentiated iTregs and control group. Our findings demonstrate that miR-21 has positive role in in-vitro generation of induced regulatory T-cells (iTregs).

Abstract
Objectives Gastrointestinal disorders caused by Salmonella enterica serovar Enteritidis (SesE) are a significant health problem around the globe. Probiotic bacteria have been shown to have positive effects on the immune responses. Lactobacillus acidophilus was examined for its capability to influence the innate immune response of HT29 intestinal epithelial cells towards SesE. The purpose of this work was to assess the effect of L. acidophilus PTCC 1643 on cultured intestinal epithelial cells infected with SesE. Methods HT29 cells were cultured in Roswell Park Memorial Institute medium supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin. The cells were treated with L. acidophilus PTCC 1643 after or before challenge with SesE. At 2 and 4 hours post-infection, we measured changes in the expression levels of TLR2 and TLR4 via real-time polymerase chain reaction. Results Treatment with L. acidophilus inhibited SesE-induced increases in TLR2 and TLR4 expression in the infected HT29 cells. Moreover, the expression of TLR2 and TLR4 in cells that were pretreated with L. acidophilus and then infected with SesE was significantly higher than that in cells infected with SesE without pretreatment. Taken together, the results indicated that L. acidophilus had an anti-inflammatory effect and modulated the innate immune response to SesE by influencing TLR2 and TLR4 expression. Conclusion Our findings suggested that L. acidophilus PTCC 1643 was able to suppress inflammation caused by SesE infection in HT29 cells and reduce TLR2 and TLR4 expression. Additional in vivo and in vitro studies are required to further elucidate the mechanisms underlying this anti-inflammatory effect.

Abstract
Increased blood cytokines is the main immunopathological process that were attributed to severe clinical outcomes in cases of influenza A/H3N2 virus infection. The study was aimed to investigate the polymorphisms of IL-1β, IL-10, IL-17, and IL-28 genes to find the possibility of their association with the clinical outcome of influenza A/H3N2 virus infection among the infected patients in Iran. This is a Case-Control study in which influenza A/H3N2 virus positive confirmed with real-time PCR were the cases. DNA samples from groups were genotyped for polymorphisms in rs16944 (IL-1β), rs1800872 (IL-10), rs2275913 (IL-17), and rs8099917 (IL-28). Confidence interval (95%CI) and Odds ratio (OR) were calculated. IL-17 rs2275913 (GG and AG) were associated with risk of infection with that were statistically significant (P < 0.05, OR = 2.08-2.94). IL-1β (rs16944) (GG) was associated with reduced risk of infection (P < 0.01, OR = 0.46). Genotype GG and GT of IL-10 (rs1800872) were associated with increased risk of infection with influenza A/H3N2 virus (P < 0.05, OR = 2.04-2.58). In addition, IL-28 (rs8099917) genotypes GG (P < 0.05, OR = 0.49) and TG (P < 0.05, OR = 0.59) were associated with reduced risk of ILI symptom while genotype TT (P < 0.01, OR = 4.31) was associated with increased risk of ILI symptom. The results of this study demonstrated that polymorphisms of genes involved in the inflammatory and anti-inflammatory process affect the outcome of disease caused by influenza A/H3N2 virus. Thorough insight on host immune response at the time of influenza A virus infection is required to ensure adequate patient care in the case of feature outbreaks. J. Med.

Abstract
There are few estimates of influenza burden in the WHO Region for the Eastern Mediterranean. In this study we estimated the burden of severe acute respiratory infection (SARI) and influenza-associated SARI (F-SARI) in selected provinces of Islamic Republic of Iran, the trends of SARI and confirmed cases of influenza (F-SARI) over 12 months (seasonality), and the age groups most at risk. Using the electronic Iranian influenza surveillance system and data of cases in sentinel hospitals of 3 selected provinces, we estimated the monthly trend (seasonality) of incidence for SARI and F-SARI, overall incidence of SARI and F-SARI and their disaggregation by age with the aid using the Monte Carlo technique. The age groups most at-risk were children aged under 2 years and adults older than 50 years.

Abstract
Background: Although several studies have confirmed the association of xenotropic murine leukemia virus-related virus (XMRV) and prostate cancer, this association is still controversial, as most studies did not detect XMRV in prostate tissue samples. Furthermore, some genetic and epidemiological studies have highlighted a role for RNase L polymorphisms, particularly R462Q, in the progression of prostate cancer. Objectives: The focus of this study was on the association of XMRV and RNase L R462Q variants with the risk of prostate cancer in Iranian patients. Patients and Methods: In this case-control study, 40 and 80 individuals with sporadic prostate cancer and benign prostatic hyperplasia, respectively, were included. The presence of XMRV was evaluated by real-time polymerase chain reaction (PCR) of integrase and nested-PCR for the gag genes. The RNase L R462Q polymorphism analysis was carried out by PCR and sequencing. Results: In a total of 40 sporadic prostate cancer and 80 benign prostatic hyperplasia cases, no XMRV was detected by real-time PCR and nested-PCR. RNase L R462Q polymorphism analysis reveals that although there was an increase in the risk of prostate cancer correlated with the Q/Q allele of RNase L at position 462, the frequencies of the RNase L R462Q alleles were not statistically significant between the prostate cancer and benign prostatic hyperplasia groups (OR = 2.75 (95% CI = 0.67 - 11.3), P = 0.29). Conclusions: These results did not support the presence of XMRV in the samples with prostate cancer and showed that RNase L R462Q variants had relatively little or no impact on the risk of prostate cancer in Iranian population.

Abstract
Aim: Roles of NS gene of influenza A virus in virulence and replication are well established but extent of its variation in seasonal influenza A (H3N2) viruses in Iran is not well known. Materials & methods: NS gene of 37 (A/H3N2) virus isolates were sequenced and analyzed for information on genetic changes. Results: Data analysis of NS1 protein revealed two amino acid substitutions E26K and Q193R in almost all strains. Substitutions in T58P in 27.0%, A86S in 13.5% and each of V11G, M81I and P85T in 2.7% Iranian strains were also observed. Mutations in NS2/NEP protein were observed in K36E, Q101L and F107S. Conclusion: Many mutations were observed for the first time in Iranian strains. Their function remains to be determined.

Abstract
Cancer stem cell (CSC) markers could serve as potential prognostic procedure. This study is aimed to investigate the local expression of doublecortin-like kinase 1 (DCLK1) and Lgr5 in colorectal cancer tissues (CRC) at both protein and messenger RNA (mRNA) level, followed by providing a comparison of the local and circulating expression pattern of these markers, based on our present and previous study. The mRNA expression level of DCLK1 and Lgr5 was evaluated using comparative real-time PCR method applying 58 fresh tumor tissues and their correspondent normal margins. Immunohistochemistry was applied to analyze the protein expression level of DCLK1 and Lgr5 in paraffin-embedded CRC tissues. The correlation of DCLK1 and Lgr5 expression pattern with clinicopathological characteristics was assessed. A higher mRNA expression level of DCLK1 (3.28-fold change, p < 0.001) and Lgr5 (2.29-fold change, p < 0.001) was observed in CRC fresh tissues compared to the normal adjacent margins, and the expression level was higher in patients with higher grade and stages of disease and patients who underwent neoadjuvant chemoradiotherapy (CRT). The protein expression level of DCLK1 and Lgr5 was also increased significantly in tumor tissues compared to normal colon tissues which were positively correlated to tumor stage and grade and neoadjuvant CRT. Taken together, the results of protein analysis were in accordance with mRNA assessment. The local expression pattern of DCLK1 and Lgr5 was also in accordance with their expression level in circulation. However, some minor inconsistencies were observed which may be attributed to several factors including the possible effect of CRT on CSC reprogramming.

Abstract
Multiple sclerosis, a debilitating autoimmune and inflammatory disease of the central nervous system, is associated with both infectious and non-infectious factors. We investigated the role of EBV infection, vitamin D level, and cytokine signature in MS patients. Molecular and serological assays were used to investigate immune biomarkers, vitamin D level, and EBV status in 83 patients with relapsing-remitting multiple sclerosis and 62 healthy controls. In total, 98.8 % of MS patients showed a history of EBV exposure compared to 88.6 % in the healthy group (p = 0.005). EBV DNA load was significantly higher in MS patients than healthy subjects (p < 0.0001). Using a panel of biomarkers, we found a distinct transcriptional signature in MS patients compared to the healthy group with mRNA levels of CD73, IL-6, IL-23, IFN-γ, TNF-α, IL-15, IL-28, and IL-17 significantly elevated in MS patients (p < 0.0001). In contrast, the mRNA levels for TGF-β, IDO, S1PR1, IL-10, and CCL-3 were significantly lower in MS patients compared to healthy controls (p < 0.0001). No significant differences were found with the mRNA levels of IL-13, CCL-5, and FOXP3. Interestingly, in MS patients we found an inverse correlation between vitamin D concentration and EBV load, but not EBNA-1 IgG antibody levels. Our data highlight biomarker correlates in MS patients together with a complex interplay between EBV replication and vitamin D levels.

Abstract
Background: Family is considered as the smallest social unit, which is the basis of forming a society and one of the effective factors for individual behaviors. When family pattern is useful, the family will be productive and otherwise it becomes nonproductive. Aim: This study aimed to investigate family process and content among families of suicide attempters, human immunodeficiency virus (HIV) positive patients, and general population in Shiraz, Southern Iran. Subjects and Methods: This was a causal-comparative study. Our study population included three groups of single men, including suicide attempters, HIV positive patients and general population in Southern Iran. Our sample size was 180 male individuals including 60 suicide attempters referring to one of hospitals in Shiraz, 60 HIV positive patients referring to Behavioral Health Consultation Center, and 60 individuals from the general population who were selected using simple sampling method and were being investigated by Samani's family process and family content questionnaires. Data were being analyzed by ANCOVA and MANCOVA. Results: The two clinical groups had a poorer situation than the general population (P < 0.001) in some dimensions of family process including decision-making and coping (P < 0.001), mutual respect, and communication (P = 0.02) when compared with the general population. HIV positive patients had significantly lower scores than suicide attempters in some dimensions of family content including financial resources, social position (P < 0.001), and place of residence (P = 0.04). The two clinical groups had a poor situation in most of the dimensions when compared with the general population (P < 0.001). Conclusions: The results of this study indicate the importance of education in the field of communication, decision-making and coping skills.

Abstract
UNLABELLED Parvovirus B19 (B19V) is a small non-enveloped single-stranded DNA (ssDNA) virus of the family Parvoviridae, the subfamily Parvovirinae, the genus Erythrovirus and Human parvovirus B19 type species. It is a common community-acquired respiratory pathogen without ethnic, socioeconomic, gender, age or geographic boundaries. Moreover, the epidemiological and ecological relationships between human parvovirus B19, man and environment have aroused increasing interest in this virus. B19V infection is associated with a wide spectrum of clinical manifestations, some of which were well established and some are still controversial, however, it is also underestimated from a clinical perspective. B19V targets the erythroid progenitors in the bone marrow by binding to the glycosphingolipid globoside (Gb4), leading to large receptor-induced structural changes triggering cell death either by lysis or by apoptosis mediated by the nonstructural (NS)1 protein. The pattern of genetic evolution, its peculiar properties and functional profile, the characteristics of its narrow tropism and restricted replication, its complex relationship with the host and its ample pathogenetic potential are all topics that are far from a comprehensive understanding. The lack of efficient adaptation to in vitro cellular cultures and the absence of animal models have limited classical virological studies and made studies on B19V dependent on molecular biology. The present review looks at the nature of this virus with the view to provide more information about its biology, which may be useful to the present and future researchers.
