Anti-Human/Mouse TL1A PerCP-eFluor® 710

Description: The Tandys1a monoclonal antibody reacts with human and mouse TL1A (TNFSF15). TL1A is a member of the TNF ligand family and is expressed by endothelial cells, tissue macrophages, monocyte-derived dendritic cells, plasma cells and lamina propria-derived lymphocytes. Among peripheral blood cells, TL1A has been shown to be expressed predominantly by CD4+CCR9+ lymphocytes. Its expression has been shown to be induced by TNF alpha, IL-1 alpha and IFN gamma. TL1A binds DR3, which has been shown to be specifically upregulated in Th17 cells among CD4+ T cells. TL1A-deficient dendritic cells are weak in their ability to support Th17 cells in vitro and show decreased severity of EAE. In vivo, TL1A has been shown to be upregulated in tissue lymphocytes of Crohn’s Disease and ulcerative colitis patients.
