General Information
| Biological Significance | Mouse IL-1beta, also called lymphocyte activating factor, endogenous pyrogen, leucocyte endogenous mediator, mononuclear cell factor, is a ~17 kDa factor produced by a wide variety of cells, including macrophages, dendritic cells, T and B cells. IL-1beta is mostly cell associated with 23% amino acid homology with IL-1 alpha. The immune regulatory role of IL-1beta is exerted on a wide range of cells including lymphocytes, epithelial cells and fibroblasts. In vivo, it induces hypotension, fever, and acute phase response. |
