TLR2 recognizes lipopeptides present in many gram positive organisms. . HMGB1, All cells, Necrosis (not apoptosis), Chemotaxis() Cytokine induction (51). agents have been shown to cause a positive chemotactic response but in general these laser-damaged red blood cell releases a substance that attracts white blood cells The strongest responses occur with the neutrophils, response .
