Pemphigus vulgaris (PV) is an acquired autoimmune blistering disease characterized by the production of autoantibodies targeting desmosomal cadherins, primarily desmoglein 1 and 3, leading to acantholysis. The etiology PV multifactorial, including genetic susceptibility. This retrospective study aimed evaluate association HLA class II alleles examine impact PV-associated on concentration anti-d...
BACKGROUND HLA class I and class II alleles have been shown to be associated with the development of dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS) in different populations. However, the majority of studies have been based on limited numbers of patients. In this study we aimed to investigate the HLA-class I and class II alleles that are positively and negatively associated with the ...
Background: The high polymorphism in the human leukocyte antigen (HLA) genes can be used as an identity of individuals to compare with other populations. This extreme polymorphism in the HLA system is accountable for the differences in alleles and haplotypes among ethnic groups, populations, and the inhabitants of many regions. Objective: To define the frequency of HLA alleles and haplotypes am...
Influenza is a major cause of morbidity and mortality. Despite vaccination, many elderly recipients do not develop a protective antibody response. To determine whether Human Leukocyte Antigen (HLA) alleles modulate seroprotection to influenza, a cohort of HLA class II-typed high-risk vaccine recipients was investigated. Haemagglutinin inhibition (HAI) titres were measured 14-40 days post-subuni...
The major histocompatibility complex (MHC) region is strongly associated with multiple sclerosis (MS) susceptibility. HLA-DRB1*15:01 has the strongest effect, and several other alleles have been reported at different levels of validation. Using SNP data from genome-wide studies, we imputed and tested classical alleles and amino acid polymorphisms in 8 classical human leukocyte antigen (HLA) gen...
Data on the genetic background of Peruvian and Bolivian populations is still scarce. Studies have shown that mestizos (i.e. mixed, but of predominantly Native American ancestry) present several HLA alleles originally described in genetically isolated Amerindian tribes, and that Peruvian and Bolivian mestizos are closely genetically related. Using Reverse Line Blot Assay, HLA typing for Class I ...
Human narcolepsy-cataplexy, a sleep disorder associated with a centrally mediated hypocretin (orexin) deficiency, is tightly associated with HLA-DQB1*0602. Few studies have investigated the influence that additional HLA class II alleles have on susceptibility to this disease. In this work, 1,087 control subjects and 420 narcoleptic subjects with cataplexy, from three ethnic groups, were HLA typ...
