Major histocompatibility complex (MHC) class II deficiency is a primary immunodeficiency disease characterized by abnormality of MHC class II molecules surface expression on peripheral blood lymphocytes and monocytes. Clinical manifestations include extreme susceptibility to viral, bacterial, and fungal infections but the immunodeficiency is not as severe as SCID (severe combined immunodeficien...

Abstract Genes of the major histocompatibility complex (MHC) have long been linked to odor signaling and recently researchers’ attention has focused on MHC structuring microbial communities how this may in turn impact odor. However, understanding mechanisms through which could affect microbiota produce a chemical signal that is both reliable strong enough ensure unambiguous transmission behavio...

Bovine viral diarrhea virus (BVDV) is an economically important pathogen of the livestock industry worldwide. BVDV is classified into cytopathic (cp) and noncytopathic (ncp), depending on its effects on cultured cells. BVDV is known to alter the host’s immune response. Of this, major histocompatibility complex (MHC) class II molecules play a central role in the development and function of the i...

BACKGROUND Cell-surface major histocompatibility (MHC) class II molecules contribute to a molecular, intercellular complex that stimulates T-cells. MHC class II molecules also activate signaling pathways leading to apoptosis. Lack of CIITA, a co-activator of the MHC class II gene promoter, is responsible for lack of MHC class II on most of the MHC class II-negative melanoma cell lines. MATERI...
