BACKGROUND Toxicity of the oral and gastrointestinal mucosa induced by high-dose melphalan is a clinical challenge with no documented prophylactic interventions or predictive tests. The aim of this study was to describe molecular changes in human oral mucosa and to identify biomarkers correlated with the grade of clinical mucositis. METHODS AND FINDINGS Ten patients with multiple myeloma (MM)...

AIM To study the major histocompatibility complex (MHC) Class II DRB1 gene polymorphism in Rohilkhandi goat using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and nucleotide sequencing techniques. MATERIALS AND METHODS DNA was isolated from 127 Rohilkhandi goats maintained at sheep and goat farm, Indian Veterinary Research Institute, Izatnagar, Bareilly. A 284...

It has been speculated that human leukocyte antigen (HLA) alleles are associated with the outcome of hepatitis B virus (HBV) infection although the data obtained from various populations have shown some inconsistencies. A total of 464 HBVinfected Korean individuals (80 spontaneously recovered [SR] and 384 chronically infected [CI]) were selected to investigate the association of HLA class II al...

OBJECTIVE To analyze the distribution of HLA-DRB1 and HLA-DQB1 alleles and its correlation with IFN-γ, IL-2, IL-6, IL-10 in HPV16 infected women with advanced cervical carcinoma. METHODS We collected 137 blood samples of cervical carcinoma patients diagnosed by pathology as cervical cancer in stage IIb-IVb before the treatment, and we gathered 175 blood samples of healthy women living in the ...

Family and epidemiological studies support a genetic susceptibility to UC and CD. Conflicting reports regarding associations between UC and HLA-DR2 and between CD and various HLA alleles have been published. The aim of this study was to determine whether molecularly defined HLA-DR genes are associated with these diseases in a Dutch group of patients. Fifty-nine unrelated Dutch UC patients and 8...

Human leukocyte antigen (HLA) class II molecule is an integral component of the immune response on which the majority of host genetic studies have concentrated. Many different HLA-II alleles have been demonstrated to play roles in HBV infection. PCR-SSOP methods were applied to determine the HLA-DRB1 genotypes of 769 unrelated healthy individuals from Han Chinese of Northeast China. The frequen...

BACKGROUND In the literature, data concerning the relationship between breast cancer and HLA class II gene polymorphisms are limited, so the aim of this study was to determine if HLA-DQB1 and HLA-DRB1 MHC class-II alleles may confer susceptibility or resistance to the disease among Jordanian females. MATERIALS AND METHODS This case control study enrolled 56 Royal Hospital breast cancer patien...

OBJECTIVE To study the association between rheumatoid arthritis (RA) and HLA and tumour necrosis factor (TNF) polymorphism in Peruvian mestizo patients in comparison with ethnically similar controls. METHODS Seventy nine patients with RA and 65 ethnically matched healthy controls were genotyped for HLA-DRB1, HLA-DQA1, HLA-DQB1, and TNFalpha and TNFbeta alleles using PCR amplification. Clinica...

background: papillon-lefevre syndrome (pls) is a rare autosomal recessive disorder characterized by palmoplantar hyperkeratosis and early development of aggressive pe-riodontitis. although cathepsin c (ctsc) gene mutations have been established in about 70-80% of pls patients, it is assumed that the patients may have dysfunctioning of immune defense mechanisms. objective: to assess the associat...
