Abstract
Malaria infection is a multifactorial disease partly modulated by host immuno-genetic factors. Recent evidence has demonstrated the importance of Interleukin-17 family proinflammatory cytokines and their genetic variants in host immunity. However, limited knowledge exists about their role in parasitic infections such as malaria. We aimed to investigate IL-17A serum levels in patients with severe and uncomplicated malaria and gene polymorphism's influence on the IL-17A serum levels. In this research, 125 severe (SM) and uncomplicated (UM) malaria patients and 48 free malaria controls were enrolled. IL-17A serum levels were measured with ELISA. PCR and DNA sequencing were used to assess host genetic polymorphisms in IL-17A. We performed a multivariate regression to estimate the impact of human IL-17A variants on IL-17A serum levels and malaria outcomes. Elevated serum IL-17A levels accompanied by increased parasitemia were found in SM patients compared to UM and controls (P < 0.0001). Also, the IL-17A levels were lower in SM patients who were deceased than in those who survived. In addition, the minor allele frequencies (MAF) of two IL-17A polymorphisms (rs3819024 and rs3748067) were more prevalent in SM patients than UM patients, indicating an essential role in SM. Interestingly, the heterozygous rs8193038 AG genotype was significantly associated with higher levels of IL-17A than the homozygous wild type (AA). According to our results, it can be concluded that the IL-17A gene rs8193038 polymorphism significantly affects IL-17A gene expression. Our results fill a gap in the implication of IL-17A gene polymorphisms on the cytokine level in a malaria cohort. IL-17A gene polymorphisms also may influence cytokine production in response to Plasmodium infections and may contribute to the hyperinflammatory responses during severe malaria outcomes.

Abstract
Cervical cancer (CC) is a multifactorial disease of which human papillomavirus (HPV) is the main etiological agent. Despite cervical Pap smear screening and anti‑HPV vaccination, CC remains a major public health issue. Identification of specific gene expression signatures in the blood could allow better insight into the immune response of CC and could provide valuable information for the development of novel biomarkers. The present study performed a transcriptomic analysis of peripheral blood mononuclear cells (PBMCs) from Senegalese patients with CC (n=31), low‑grade cervical intraepithelial neoplasia (CIN1; n=27) and from healthy control (CTR) subjects (n=29). Individuals in the CIN1 and CTR groups exhibited similar patterns in gene expression. A total of 182 genes were revealed to be differentially expressed in patients with CC compared with individuals in the CIN1 and CTR groups. The IL1R2, IL18R1, MMP9 and FKBP5 genes were the most upregulated, whereas the T‑cell receptor α gene TRA was the most downregulated in the CC group compared with in the CIN1 and CTR groups. The pathway enrichment analysis of the differentially expressed genes revealed pathways directly and indirectly linked to inflammation. To the best of our knowledge, the present study is the first large transcriptomic study on CC performed using PBMCs from African women; the results revealed the involvement of genes and pathways related to inflammation, most notably the IL‑1 pathway, and the involvement of downregulation of the T‑cell receptor α, a key component of the immune response. Several of the stated genes have already been reported in other cancer studies as putative blood biomarkers, thus reinforcing the requirement for deeper investigation. These findings may aid in the development of innovative clinical biomarkers for CC prevention and should be further replicated in other populations.

Abstract
Background Host genetic factors contribute to the variability of malaria phenotypes and can allow a better understanding of mechanisms involved in susceptibility and/or resistance to Plasmodium falciparum infection outcomes. Several genetic polymorphisms were reported to be prevalent among populations living in tropical malaria-endemic regions and induce protection against malaria. The present study aims to investigate the prevalence of HBB (chr11) and G6PD (chrX) deficiencies polymorphisms among Senegalese populations and their associations with the risk for severe Plasmodium falciparum malaria occurrence. Methods We performed a retrospective study with 437 samples, 323 patients recruited in hospitals located in three different endemic areas where malaria episodes were confirmed and 114 free malaria controls. The patients enrolled were classified into two groups: severe malaria (SM) (153 patients) and uncomplicated malaria (UM) (170 patients). PCR and DNA sequencing assessed host genetic polymorphisms in HBB and G6PD. Using a multivariate regression and additive model, estimates of the impact of human HBB and G6PD polymorphisms on malaria incidence were performed. Results Six frequent SNPs with minor allele frequencies (MAF) > 3% were detected in the HBB gene (rs7946748, rs7480526, rs10768683, rs35209591, HbS (rs334) and rs713040) and two in the G6PD gene (rs762515 and rs1050828 (G6PD-202 G > A). Analysis of selected HbS polymorphism showed significant association with protective effect against severe malaria with a significant p-value = 0.033 (OR 0.38, 95% CI [0.16-0.91]) for SM vs. UM comparison. Surprisingly, our study did not identify the protective effect of variant HbC polymorphism against severe malaria. Finally, we found some of the polymorphisms, like HbS (rs334), are associated with age and biological parameters like eosinophils, basophils, lymphocytes etc. Conclusion Our data report HBB and G6PD polymorphisms in the Senegalese population and their correlation with severe/mild malaria and outcome. The G6PD and HBB deficiencies are widespread in West Africa endemic malaria regions such as The Gambia, Mali, and Burkina Faso. The study shows the critical role of genetic factors in malaria outcomes. Indeed, genetic markers could be good tools for malaria endemicity prognosis.

Abstract
Skin aging is an ineluctable process leading to the progressive loss of tissue integrity and is characterized by various outcomes such as wrinkling and sagging. Researchers have identified impacting environmental factors (sun exposure, smoking, etc.) and several molecular mechanisms leading to skin aging. We have previously performed genome-wide association studies (GWAS) in 502 very-well characterized French women, looking for associations with four major outcomes of skin aging, namely, photoaging, solar lentigines, wrinkling, and sagging, and this has led to new insights into the molecular mechanisms of skin aging. Since individual SNP associations in GWAS explain only a small fraction of the genetic impact in complex polygenic phenotypes, we have made the integration of these genotypes into the reference Kegg biological pathways and looked for associations by the gene set enrichment analysis (GSEA) approach. 106 pathways were tested for association with the four outcomes of skin aging. This biological pathway analysis revealed new relevant pathways and genes, some likely specific of skin aging such as the WNT7B and PRKCA genes in the “melanogenesis” pathway and some likely involved in global aging such as the DDB1 gene in the “nucleotide excision repair” pathway, not picked up in the previously published GWAS. Overall, our results suggest that the four outcomes of skin aging possess specific molecular mechanisms such as the “proteasome” and “mTOR signaling pathway” but may also share common molecular mechanisms such as “nucleotide excision repair.”

Abstract
Interleukin (IL)-1 family members are key players in inflammatory processes but have been the subject of few studies of acquired immunodeficiency syndrome (AIDS). To better evaluate the impact of the IL-1 family on AIDS development, we genotyped the IL1 alpha , IL1 beta , IL1Ra, and IL1R1 genes in 245 slow progressor (SP) and 82 rapid progressor (RP) human immunodeficiency virus type 1-seropositive patients as well as in 446 control subjects, all of whom were of white ethnicity. One hundred sixteen frequent polymorphisms were identified, of which 23 were newly characterized by our study. Many putative associations were found between single-nucleotide polymorphism (SNP) or haplotype alleles and the extreme profiles of progression. Most of them corresponded to weak associations (.01<P<.05); however, the SNP IL1Ra_2134 exhibited a consistent association, found at the level of the SNP, haplotypes, and haploblocks, when the SP and control populations were compared (P=.0002). The IL-1-dependent inflammatory response is, thus, likely to play a role in AIDS progression via the regulation of IL-1Ra expression. This association will need to be confirmed in other AIDS cohorts, and experiments will also have to be performed to unravel the biological mechanisms at work. The data presented here will be useful for future genomic studies of the IL-1 family members in other infectious and chronic inflammatory diseases.

Abstract
We have undertaken a systematic genomic approach in order to explore the role of the interferon alpha (IFN-alpha) pathway in AIDS disease development. As it is very difficult to genotype the IFN-alpha gene itself since it has many pseudo-genes, we have focused our interest on the genetic polymorphisms of the IFN-alpha receptor 1 (IFNAR1). We genotyped the Genetics of Resistance to Immunodeficiency Virus (GRIV) cohort composed of patients with extreme profiles of progression to AIDS, slow progressors (SP) and rapid progressors (RP), as well as seronegative controls (CTR). We identified 19 single nucleotide polymorphisms (SNPs) with a minor allele frequency (MAF) greater than 1% among which two were newly characterized by our study. We found putative associations with AIDS disease development for four SNP alleles and for three haplotypes. The most interesting signals were found for two SNPs in linkage disequilibrium, the SNP IFNAR1_18339 corresponding to a Val168Leu mutation in the extracellular domain of the protein and the intronic SNP, IFNAR1_30127. The intronic SNP IFNAR1_30127 yielded a strong signal both when comparing SP with CTR (P=0.002) and RP with CTR (P=0.005) while IFNAR1_18339 yielded a smaller signal because less patients were analyzed; these SNPs could thus be involved in AIDS progression or in susceptibility to human immunodeficiency virus 1 (HIV-1) infection. Interestingly, two independent studies have previously pointed out the SNP IFNAR1_18339 in susceptibility to multiple sclerosis and to malaria. This is the first work investigating the polymorphisms of the IFNAR1 gene in AIDS. Our results which point out a possible role for the IFN-alpha pathway in susceptibility to HIV-1 infection or progression to AIDS need a necessary confirmation by genomic studies in other AIDS cohorts.
