MHC-based sexual selection is known to involve olfactory mechanisms in such vertebrate taxa as fish, mice, humans, primates, birds, and reptiles. [1] At its simplest level, humans have long been acquainted with the sense of olfaction for its use in determining the pleasantness or the unpleasantness of one's resources, food, etc.
The major histocompatibility complex (MHC) is a large locus on vertebrate DNA containing a set of closely linked polymorphic genes that code for cell surface proteins essential for the adaptive immune system. These cell surface proteins are called MHC molecules. Its name comes from its discovery during the study of transplanted tissue ...
There are three major and two minor MHC class II proteins encoded by the HLA. The genes of the class II combine to form heterodimeric (αβ) protein receptors that are typically expressed on the surface of antigen-presenting cells. Major MHC class II proteins only occur on antigen-presenting cells, B cells, and T cells. [1] HLA-DP
In the 2021 Chandigarh Municipal Corporation election, SAD and BJP contested separately without an alliance. Aam Aadmi Party (AAP) contested this election for the first time. [2] The number of wards of the corporation were increased from 26 in 2016 to 35 in the 2021 election. [3]
The MHC class I molecule is then, in turn, loaded with peptides in the lumen of the ER. The peptide-loading process involves several other molecules that form a large multimeric complex called the Peptide loading complex [12] consisting of TAP, tapasin, calreticulin, calnexin, and Erp57 . Calnexin acts to stabilize the class I MHC α chains ...

In some cells, antigens bind to recycled MHC class II molecules while they are in the early endosomes, while other cells such as dendritic cells internalize antigens via receptor-mediated endocytosis and create MHC class II molecules plus peptide in the endosomal-lysosomal antigen processing compartment which is independent of the synthesis of ...
HLA-A projected away from the cell surface and presenting a peptide sequence. The peptide-MHC complex presents a surface that looks like an altered self to the TCR. [11] The surface consisting of two α helices from the MHC and a bound peptide sequence is projected away from the host cell to the T cells, whose TCRs are projected away from the T cells towards the host cells.
