WebBecause upregulation of lymphotoxin α1β2 in pre-B cells carrying unrepaired DSBs promotes IL7 downregulation, we speculate that this mechanism may contribute to the efficient elimination of pre-leukemic B cell progenitors in vivo. Whether the same mechanism is responsible for lymphotoxin α1β2 upregulation in AML cells remains to be determined. Web28 ian. 2011 · Lymphotoxin-α1β2, the ligand of LTBR, was reported to promote the inflammatory effects in HUVECs through NF-κB pathway [13], [14]. The interaction between AdipoR1 and LTBR prompted us to think that the activation of AdipoR1 might influence LTBR-activated NF-κB pathway. We therefore examined the effect of adiponectin on …
WebResults: Inhibition of lymphotoxin α1β2/lymphotoxin-β receptor interactions was associated with increased severity of Citrobacter rodentium induced colitis, as indicated by increased disease-related mortality, more severe weight loss, intestinal bacterial abscesses, and a higher burden of Citrobacter rodentium in the spleen and liver of −/− and … Web1 iul. 2024 · The members of the Tumor Necrosis Factor (TNF) superfamily, the ligand lymphotoxin α1β2 (LTα1β2) and its unique receptor lymphotoxin β receptor (LTβR), …
Web1 feb. 2001 · A recombinant antibody-lymphotoxin-α fusion protein induced an adaptive immune response protecting mice from melanoma. Importantly, this fusion protein elicited the formation of a lymphoid-like tissue in the tumor microenvironment containing L-selectin+ T cells and MHC class II+ antigen-presenting cells, as well as B and T cell aggregates. … WebOn one hand, CXCL13 secreted by FDCs upregulates membrane lymphotoxin α1β2 (LTαβ) on B cells. On the other hand, LTαβ interacts with the lymphotoxin-β receptor (LTβR) on FDCs and triggers FDC development, mutation, and CXCL13 production . In GCs, the expression of LTαβ on B cells is independent of CXCL13 .
Web15 apr. 2010 · Recruitment of LTi cells that express the TNF family molecule lymphotoxin α1β2 to the LN anlagen allows engagement of lymphotoxin β receptor (LTβR)-expressing stromal cells. Subsequently, activation of two different pathways of the NF-κB transcription factor results in expression of high levels of ICAM-1, VCAM-1, chemokines, and …
