LT-BetaR Pathway

Much of the efficiency of the immune system is attributed to the high degree of spatial and temporal organization in the secondary lymphoid organs. Signaling through the LT-BetaR (Lymphotoxin-Beta Receptor) pathway is a crucial element in the maintenance of this organised microenvironment (Ref.1). LT-BetaR, a member of the TNFR (Tumor Necrosis Factor Receptor) superfamily, plays important roles in embryonic development and organization of secondary lymphoid tissues and maintenance of their architecture in adults (Ref. 2). LT-BetaR is expressed on most cell types including cells of fibroblast, epithelial, and myeloid lineages but not on T or B lymphocytes. It can bind to specific ligands, such as: the membrane form of lymphotoxin heterotrimmer, LT-Alpha1Beta2 (Lymphotoxin-Alpha1Beta2); and homotrimmer LIGHT (name derived from: homologous [...]
