MHC class II presentation. MHC class II molecules are expressed by APCs, such as dendritic cells (DC), macrophages and B cells (and, under IFNγ stimuli, by mesenchymal stromal cells, fibroblasts and endothelial cells, as well as by epithelial cells and enteric glial cells).

The main function of major histocompatibility complex (MHC) class II molecules is to present processed antigens, which are derived primarily from exogenous sources, to CD4(+) T-lymphocytes. MHC class II molecules thereby are critical for the initiation of the antigen-specific immune response. Beside …

ADA‑brist har i Sverige bara setts hos barn som har sitt ursprung i Somalia och Mellanöstern. Det  MHC Class II molecules are a class of major histocompatibility complex (MHC) molecules normally found only on professional antigen-presenting cells such as dendritic cells, mononuclear phagocytes, some endothelial cells, thymic epithelial cells, and B cells. These cells are important in initiating immune responses. Class II MHC molecules are the only known ligands for LAG-3132; signaling through which results in enhanced Treg function134 and abrogated CD8+ T cell effector function.137 From: Translational Immunotherapy of Brain Tumors, 2017 Class II MHC genes encode glycoproteins expressed primarily on APCs, where they present processed antigenic peptides to TH cells. Class III MHC genes encode, various secreted proteins that have immune functions, including components of the complement system and molecules involved in inflammation (e.g. TNF, Heat Shock proteins). The main function of major histocompatibility complex (MHC) class II molecules is to present processed antigens, which are derived primarily from exogenous sources, to CD4(+) T-lymphocytes.

MHC klass 1 presenterar antigener till cytotoxiska T-celler medan MHC-klass 2 De tre klasserna MHC-molekyler kan identifieras som klasserna 1, 2 och 3.

Before their exposition on the cell surface, the MHC class II molecules react with endocytosed exogenous antigens, which are then presented to the T cells. The antigen-binding grove between MHC class II alpha and beta chain is open at both ends and is 15-24 amino acid residues long. The main function of major histocompatibility complex (MHC) class II molecules is to present processed antigens, which are derived primarily from exogenous sources, to CD4(+) T-lymphocytes. MHC class II molecules thereby are critical for the initiation of the antigen-specific immune response.

Klass I finns på alla celler utom rödablodkroppar. Klass II finns på APC. Klass II består av 2 st MHC-kodade polypeptidkedjor. Trots denna skillnad är den 3 dimensionella strukturen mycket lika. Vad består MHC klass I, resp II,  Sen förstår jag inte riktigt skillnaden mellan MHC klass I och II. 'Klass I-molekylerna finns på kroppens alla celler och "håller fram" fragment  MHC II. – Antigener från extracellulära bakterier. – Aktiverar CD4+ T-hjälpar celler.
