History and naming of human leukocyte antigens print that page

A person can have 2 antigen proteins per genetic-locus (one gene from each parent). During development the immune system determines these two antigens are 'self' antigens or ( autoantigens ) and turns off the destructive response. However when tissues are transferred to another person they

one of the fundamental strengths of the adaptive immune system , that is, its ability to target antigens with high specificity. More importantly, the large number of activated T-cells secrete large amounts of cytokines (the most important of which is TNF-alpha ). TNF-alpha is particularly

CD19 print that page

CD19 is expressed on follicular dendritic cells and B cells. In fact, it is present on B cells from earliest recognizable B-lineage cells during development to B-cell blasts but is lost on maturation to plasma cells . It primarily acts as a B cell co-receptor in conjunction with CD21 and

PBB_Protein_ELAVL4_image

The HuD/ELAVL4 protein is an RNA-binding protein . [ 3 ] HuD is expressed only in neurons and it binds to AU-rich element -containing mRNAs. As a result of this interaction the half-life of the transcript is increased. HuD is important in neurons during brain development and plasticity. [
