[https://www.uniprot.org/uniprot/TNFL4_HUMAN TNFL4_HUMAN] Genetic variations in TNFSF4 influence susceptibility to systemic lupus erythematosus (SLE) [MIM:[https://omim.org/entry/152700 152700]. SLE is a chronic, inflammatory and often febrile multisystemic disorder of connective tissue. It affects principally the skin, joints, kidneys and serosal membranes. It is thought to represent a failure of the regulatory mechanisms of the autoimmune system. Note=The upstream region of TNFSF4 contains a single risk haplotype for SLE, which is correlated with increased expression of both cell-surface TNFSF4 and TNFSF4 transcripts. Increased levels of TNFSF4 are thought to augment T-cell-APC interaction and the functional consequences of T-cell activation, thereby destabilizing peripheral tolerance.<ref>PMID:18059267</ref>

OX40 is a T cell costimulator activated by OX40L. Blockade of the OX40L-OX40 interaction has ameliorative effects in animal models of T cell pathologies. In order to better understand the interaction between OX40 and OX40L, we have determined the crystal structure of murine OX40L and of the human OX40-OX40L complex at 1.45 and 2.4 A, respectively. These structures show that OX40L is an unusually small member of the tumor necrosis factor superfamily (TNFSF). The arrangement of the OX40L protomers forming the functional trimer is atypical and differs from that of other members by a 15 degrees rotation of each protomer with respect to the trimer axis, resulting in an open assembly. Site-directed changes of the interfacial residues of OX40L suggest this interface lacks a single "hot spot" and that instead, binding energy is dispersed over at least two distinct areas. These structures demonstrate the structural plasticity of TNFSF members and their interactions with receptors.
