The emerging role of HLA-C in HIV-1 infection.

چکیده
Recently, genome-wide association studies have identified the major histocompatibility complex class I protein HLA-C as an important molecule that affects HIV disease progression. The association between HLA-C and HIV disease outcome was originally determined through a single nucleotide polymorphism (SNP) 35 kb upstream of the HLA-C locus. More recent work has focused on elucidating the functional significance of the -35 SNP, and several groups now have demonstrated HLA-C surface expression to be a key element in control of HIV viral load, with higher surface expression associating with slower disease progression. Most recently, control of HLA-C surface expression has been correlated with the presence of microRNA binding sites that affect HLA-C expression and control of HIV disease. This review highlights these results and explores the ways in which HLA-C surface expression could affect immune system function in the setting of HIV disease.

Background: Abacavir is an anti-retroviral medication used to treat HIV infected/AIDS patients and its efficacy has been proven in randomized clinical trials. The most significant adverse reaction associated with abacavir is the acute hypersensitivity phenomenon which manifests in many forms and in severe cases could result in death. Hypersensitivity reaction to abacavir has been closely linked...
متن کاملRole of HLA-G 14 bp Indel polymorphism on susceptibility to HTLV-1 infection in blood donors of Khorasan Razavi Blood Center
Abstract Background and Objectives The HLA-G antigen is a non-classical HLA class-I with limited polymorphism. Several studies have indicated the role of a 14 bp Indel polymorphism rs371194629 in the 3'-UTR region of the HLA-G in acquisition of HTLV-1 infection. In this study, we investigated the correlation between the genotypes of this polymorphism and HTLV-1 infection in blood donors of Khor...

Background: It has been arguedthat unprecedented degree of human leukocyte antigen (HLA) loci polymorphism within a population is requiredto avoid the devastating effects of infectious diseases. The present study was conducted to determine the associations between some of HLA classI genes and the outcome of hepatitis B virus (HBV) infection. Methods: Using sequential sampling method, 64 individ...

Background and purpose: HILA-G is an immunomodulatory molecule and alteration of its expression is prevalent during viral infections. HLA-G expression in HIV-positive patients has been inconsistent between different studies and some suggest that Interleukin-10 (IL-10) influences the expression of HLA-G. The aim of this research was to investigate the expression of IL-10 in HIV-positive patients...

Background and Purpose: Candida species are the common opportunistic pathogens during the course of human immunodeficiency virus (HIV) infection. Oropharyngeal candidiasis (OPC) is generally known as the initial sign of HIV infection. The aim of this study was to compare demographic characteristics and frequency of Candida species between HIV/AIDS patients and non-HIV subjects in Kerman, southe...
