OX40-OX40 ligand interaction through T cell-T cell contact contributes to CD4 T cell longevity.
Signals through the OX40 costimulatory receptor on naive CD4 T cells are essential for full-fledged CD4 T cell activation and the generation of CD4 memory T cells. Because the ligand for OX40 is mainly expressed by APCs, including activated B cells, dendritic cells, and Langerhans cells, the OX40-OX40 ligand (OX40L) interaction has been thought to participate in T cell-APC interactions. Althoug...
متن کاملOX40/OX40 Ligand Interactions in T-Cell Regulation and Asthma
The OX40 receptor is preferentially expressed by T cells, and its cognate ligand OX40L is primarily expressed by antigen-presenting cells such as dendritic cells following activation by thymic stromal lymphopoietin (TSLP). TSLP is released by the bronchial epithelium, airway smooth muscle, and some inflammatory cells in response to numerous insults such as allergens, viruses, and physical damag...
متن کاملComparison of OX40 ligand and CD70 in the promotion of CD4+ T cell responses.
The TNF superfamily members CD70 and OX40 ligand (OX40L) were reported to be important for CD4(+) T cell expansion and differentiation. However, the relative contribution of these costimulatory signals in driving CD4(+) T cell responses has not been addressed. In this study, we found that OX40L is a more important determinant than CD70 of the primary CD4(+) T cell response to multiple immunizat...
متن کاملThe T cell-B cell interaction via OX40-OX40L is necessary for the T cell-dependent humoral immune response
Recent in vitro studies have established that activated B cells express OX40 ligand (L), a member of the tumor necrosis factor/nerve growth factor family of cytokines, and become stimulated to proliferate and secrete immunoglobulin (Ig) after cross-linking of OX40L by its counterreceptor OX40, which is expressed on activated T cells. In the present study we investigated the in vivo role of this...
متن کاملTSLP-activated dendritic cells induce an inflammatory T helper type 2 cell response through OX40 ligand
We recently showed that dendritic cells (DCs) activated by thymic stromal lymphopoietin (TSLP) prime naive CD4(+) T cells to differentiate into T helper type 2 (Th2) cells that produced high amounts of tumor necrosis factor-alpha (TNF-alpha), but no interleukin (IL)-10. Here we report that TSLP induced human DCs to express OX40 ligand (OX40L) but not IL-12. TSLP-induced OX40L on DCs was require...
