生化机理
Lymphotoxin alpha (LT-alpha ), and Lymphotoxin beta (LT-beta ) are pro-inflammatory TNF superfamily ligands that play important roles in immune system development. The 25 kDa mature human LT-alpha is a secreted protein that shares 75% amino acid (aa) sequence identity with mouse and rat LT-alpha. The 33 kDa mature human LT-beta is a type II transmembrane protein that shares 73% aa sequence identity with mouse and rat LT-beta within common regions of their extracellular domains. Relative to the human protein, mouse and rat LT-beta have a 66 aa or 65 aa insertion within the ECD, respectively. LT-alpha can be secreted as a homotrimer that binds and activates TNF RI/TNFRSF1A, TNF RII/TNFRSF1B, HVEM/TNFRSF14, and Troy/TNFRSF19. LT-alpha is required for development of the spleen, lymph nodes, and Peyer’s patches. It also regulates T cell homing to the gut and IgA induction. In addition, LT-alpha can form membrane-associated heterotrimers with two copies of LT-beta on the surface of B, T, LTi, and ILC3 cells. The Lymphotoxin alpha 1/ beta 2 heterotrimer binds and activates the Lymphotoxin beta R/TNFRSF3 (LT beta R) which is expressed on macrophages, dendritic cells, hepatocytes, intestinal epithelial cells (IEC), follicular dendritic cells (FDC), and high endothelial venules (HEV). LT beta R also serves as a receptor for LIGHT/TNFSF14. LT-alpha 1/ beta 2 promotes the development of FDC networks and HEV in lymphoid tissue, the class switching of immature B cells for IgA production, and the production of homeostatic IL-22 by ILCs. It can be shed by ADAM17 or MMP-8 mediated cleavage, and the released heterotrimer circulates in the serum and is elevated in synovial fluid of rheumatoid arthritis patients.
