The HLA-DR4 family of haplotypes consists of series of distinct DR and DS molecules
Among DR4-associated HLA-D antigens, distinct and consistent structural variations were found for the products of two human "Ia-like" loci, DR and DS. Analysis of neuraminidase-treated immunoprecipitated DR molecules from 15 HLA-DR4-associated HLA-D homozygous B-lymphoblastoid cell lines by two dimensional polyacrylamide gel electrophoresis identified five distinct DR beta chains. In addition, ...
متن کاملDiversity of Extended HLA-DRB1 Haplotypes in the Finnish Population
The Major Histocompatibility Complex (MHC, 6p21) codes for traditional HLA and other host response related genes. The polymorphic HLA-DRB1 gene in MHC Class II has been associated with several complex diseases. In this study we focus on MHC haplotype structures in the Finnish population. We explore the variability of extended HLA-DRB1 haplotypes in relation to the other traditional HLA genes an...
متن کاملpH stability of HLA-DR4 complexes with antigenic peptides.
Complexes between antigenic peptides and class II proteins of the major histocompatibility complex (MHC) trigger cellular immune responses. These complexes usually dissociate more rapidly at mildly acidic pH, where they are formed intracellularly, as compared to neutral pH, where they function at the cell surface. This paper describes the pH dependence of the dissociation kinetics of complexes ...
متن کاملIncrease of HLA-DR4 in melanoma patients from Alabama.
This report describes the association of HLA-DR phenotypes in a population of 91 Caucasian melanoma patients compared with 106 Caucasian controls from the Sunbelt region of the United States. Over 75% of both patients and controls were born in Alabama or a surrounding state. There was a significant increase in the frequency of HLA-DR4 (chi 2 = 12.8; rho = 0.0003). This was present in 38.5% of t...
متن کاملMapping the genetic diversity of HLA haplotypes in the Japanese populations
Japan has often been viewed as an Asian country that possesses a genetically homogenous community. The basis for partitioning the country into prefectures has largely been geographical, although cultural and linguistic differences still exist between some of the districts/prefectures, especially between Okinawa and the mainland prefectures. The Major Histocompatibility Complex (MHC) region has ...
