Immunogenetic host factors are associated with susceptibility or protection to tuberculosis (TB). Strong associations of HLA class II genes with TB are reported. We analyzed the HLA-DRB1*04 alleles to identify subtypes associated with pulmonary TB and their interaction with risk factors such as alcohol, smoking, and gender in 316 pulmonary TB patients and 306 healthy individuals from the Brazil...

Increasing evidences indicate that the abnormal DNA methylation is involved in the pathogenesis of psoriasis. A number of SNPs in HLA-DRB1 have been found being associated with the risk of psoriasis, however it is unclear that metylation status within HLA-DRB1 in psoriasis. Here, DNA and RNA were obtained from epidermis of 56 patients with plaque psoriasis and 28 healthy volunteers served as th...

Background and aims SLE is multisystem autoimmune disease, having known HLA-DRB1*15 and DRB1*03 risk alleles and an association with EBV in the Caucasoid population. We compared the association of HLA-DRB1 and EBV in North Indian cohort of adult and paediatric SLE Methods We analysed 109 adult SLE (aSLE) and 52 paediatric SLE (pSLE) with 278 age and sex matched control adult (CA) and paediatric...

This study aimed to review and quantitatively analyze (1) the association of aplastic anemia (AA) with human leukocyte antigen (HLA)-DRB1*15 and HLA-DRB1*15:01 polymorphisms and (2) the association of HLA-DRB1*15 and HLA-DRB1*15:01 polymorphisms with response to immunosuppressive therapy (IST) in AA. Published studies have reported conflicting and heterogeneous results regarding the association...

Background: Different studies have demonstrated that a small proportion of healthy individuals receiving the hepatitis B (HB) vaccine do not produce protective levels of anti-HB antibody, a phenomenon which could be linked to certain human leukocyte an-tigen (HLA) class-II alleles or haplotypes. Objectives: The present study was under-taken to determine the frequency of HLA class-II alleles in ...

PURPOSE We investigated whether particular HLA-DRB1 polymorphisms contribute to egg allergy development in Korean children with atopic dermatitis (AD). METHODS HLA-DRB1 alleles were determined by PCR-sequence-specific oligonucleotide (SSO) and PCR-single-strand conformation polymorphism (SSCP) methods in 185 patients with AD and 109 normal control (NC) subjects. AD patients were divided into ...

We explore the possibility of resolving an image of a damped Lyα (DLA) system in absorption against an extended, diffuse background X–ray source. Typical columns of neutral hydrogen in DLA systems are high enough to block out up to ∼ 30% of the soft X–ray flux at an observed photon energy of 0.5 keV, and we find that ∼ 1% of the area of extended X–ray sources at z & 1 have their 0.5 keV flux re...

We report the detection, both in line and continuum emission, of a galaxy responsible for a damped Lyα absorption (DLA) system at z = 3.15 projected 2.3 from QSO 2233+131. The star formation rate implied by both the Lyα and restframe far-UV continuum is ∼ 7 M⊙ yr . The galaxy also shows no sign of an active nucleus and has blue colors, both consistent with it being observed early in its star fo...

AIM To determine genetic polymorphisms at human leukocyte antigen (HLA)-A, -B, and -DRB1 loci in Han population of Xi'an city in China. METHODS Polymerase chain reaction-based reverse line-strip sequence specific oligonucleotide hybridization was used to determine the alleles of HLA-A, -B, and -DRB1 in 516 unrelated, healthy individuals of Han population in Xi'an. Allele frequencies at HLA-A,...

Cytoplasmic protein aggregates are one of the pathological hallmarks of neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Several RNA-binding proteins have been identified as components of inclusion bodies. Developmentally regulated RNA-binding protein 1 (Drb1)/RNA-binding motif protein 45 is an RNA-binding protein that was ...
