Background: Lymphotoxin beta R/TNFRSF3

Lymphotoxin beta receptor (LT beta R), previously called TNF RIII or TNF R‑related protein (TNF Rrp), is a type I transmembrane glycoprotein within the TNF receptor superfamily, designated TNFRSF3 (1‑3). Cynomolgus monkey and rhesus macaque LT beta R cDNA encodes 435 amino acids (aa) including a 30 aa signal peptide, a 197 aa extracellular domain (ECD), a 21 aa transmembrane domain, and a 187 aa cytoplasmic domain. The ECD contains four cysteine‑rich motifs characteristic of the TNF receptor superfamily (1, 2). Within the ECD cynomolgus monkey LTBR shares 65‑75% aa sequence identity with human, mouse, rat, canine, porcine, equine and bovine LT beta R. Soluble LT beta R can be formed by proteolytic cleavage of the ECD, and is an inhibitor of transmembrane LT beta R, as is recombinant LT beta R, which inhibits autoimmunity (3‑6). LT beta R is expressed by visceral, lymphoid, and other stroma, epithelia and myeloid cells, but not lymphocytes (2, 4). LT beta R ligands include homotrimers of LIGHT (TNFSF14; also a ligand for HVEM) and the heterotrimeric lymphotoxin LT alpha 1/ beta 2 (3, 4, 6). Depending on the cell type and expression of TRAF3, activation of LT beta R has been shown to induce canonical (IKK/RelA; pro‑inflammatory) or alternative (NIK/RelB; lymphoid organogenic) NF kappa B activation (6, 7). LT beta R is expressed on mesenchymal stromal organizing cells that give rise to stroma of primary (thymus), secondary (tonsils, lymph nodes and Peyers patches) and tertiary (ectopic inflammatory) lymphoid structures (3‑5, 8‑10). Secondary immune tissues are absent in LT beta R‑deficient mice (3-5). LT beta R engagement induces production of IL‑7, RANK, TRANCE/RANK L, VEGF‑C, adhesion molecules such as VCAM‑1, ICAM‑1 and MAdCAM, and chemokines such as CXCL13, CCL19 and CCL21 (3, 8 ‑ 10). LT beta R is expressed by hepatocytes, is up‑regulated in regeneration, hepatitis and hepatocellular carcinoma, and influences lipid metabolism and atherosclerosis (4, 6, 11). It regulates cell growth and can initiate inflammation‑related carcinogenesis (6, 11).
