Ly-49 mediates EL4 lymphoma adhesion to isolated class I major histocompatibility complex molecules

Ly-49 is a recently identified cell surface molecule expressed on a subpopulation of natural killer (NK) cells and certain T lymphomas. It has been suggested, based on gene transfection and antibody blocking studies, that Ly-49 is a negative regulator of NK lytic activity, possibly through an interaction with target cell class I molecules. However, it has not been demonstrated that class I mole...

Recognition of class I major histocompatibility complex molecules by Ly- 49: specificities and domain interactions

Ly-49 is a family type II transmembrane proteins encoded by a gene cluster on murine chromosome 6. One member of this family, Ly-49A, is expressed by a natural killer (NK) cell subset, binds to class I major histocompatibility complex (MHC) molecules, and blocks the killing of target cells bearing the appropriate H-2 antigens. Here we show that another member of this family which is expressed b...

Major Histocompatibility Complex, Class I, B

Description The genes of the Human Leukocyte Antigen (HLA) system reside on chromosome 6, and code for cellsurface proteins that play a crucial role in the presentation of endogenic peptides to effector cells of the immune system. The HLA Class I protein molecule is a heterodimer, made up of two chains; a heavy one and a light one (beta 2 microglobulin). The HLA-B gene is one of the three HLA C...

Frequency of Major Histocompatibility Antigens Class I in Mazandaran Province

 Background and purpose: Major histocompatibility antigens are the most polymorphic components of the immune system. The purpose of this study was to determine the frequency of human leukocyte antigens (HLA) in a population in Mazandaran province, Iran. Materials and methods: In a cross sectional study, peripheral blood samples were obtained from 550 people in Immunogenetics Research Center af...

Mice lacking major histocompatibility complex class I and class II molecules.

Mice lacking major histocompatibility complex (MHC) antigens were generated by mating beta 2-microglobulin-deficient, and therefore class I-deficient, animals with MHC class II-deficient animals. When housed under sterile conditions, the resulting MHC-deficient mice appear healthy, survive for many months, and breed successfully. Phenotypically, MHC-deficient mice are depleted of CD4+ and CD8+ ...
