Endothelial TLR2 promotes proangiogenic immune cell recruitment and tumor angiogenesis
Science for just $15 USD. A shared Toll for innate immunity Toll-like receptor 2 (TLR2) is found in various tissues but is best known for its role in the innate immune system of activating sentinel immune cells in response to infection. Using conditional knockout mice, McCoy et al. found that TLR2 also mediated innate immune signaling within the endothelium. TLR2 in endothelial cells activated proinflammatory signaling that promoted angiogenesis and immune cell recruitment in response to various “danger” signals, such as those produced during infection or tissue damage. Endothelial TLR2 ...
