Baboon Class I MHC Expression in the Yellow Hildebrand

Class I MHC Expression in the Yellow Baboon 1 , 2

Class I MHC expression in the yellow baboon.

MHC class I molecules play a crucial role in the immune response to pathogens and vaccines and in self/non-self recognition. Therefore, characterization of MHC class I gene expression of Papio subspecies is a prerequisite for studies of immunology and transplantation in the baboon (papio hamadryas). To elucidate MHC class I expression and variation within Papio subspecies and to further investi...

SUSCEPTIBILITY OF HUMAN WM MELANOMA CELL LINES TO NK AND LAK CYTOTOXICITY AND THEIR RELEVANCE TO THE LEVEL OF MHC CLASS I AND ICAM-l ANTIGEN EXPRESSION

The effect of natural killer (NK) cells and lymphokine activated killer ( LAK) cells was studied on a group of human melanoma cell lines. Peripheral blood from healthy volunteers was utilized as a fresh source of natural killer cells and rhI L-2 for producing LAK cells. The cytotoxicity of effector cells was quantified using a 4 hour SI determining the density of antigen expression on tumor...

Human Papillomavirus and Cancer - Immunological Consequences of MHC Class I Down-Regulation

Few studies have been conducted on the causative factors associated with the development of cancer. Infection by high risk human papillomaviruses (HPVs) have been implicated as causative agents in a variety of cancers. HPV is capable of evading immune system and establishing persistent infections. Prolonged infection and lesion maintenance are associated with higher risk of neoplastic progressi...

Human herpesvirus 7 U21 tetramerizes to associate with class I major histocompatibility complex molecules.

UNLABELLED The U21 gene product from human herpesvirus 7 binds to and redirects class I major histocompatibility complex (MHC) molecules to a lysosomal compartment. The molecular mechanism by which U21 reroutes class I MHC molecules to lysosomes is not known. Here, we have reconstituted the interaction between purified soluble U21 and class I MHC molecules, suggesting that U21 does not require ...
