Functional crosstalk between CD36 and CD47 signaling. In vascular cells ligation of CD36 by amyloid-β or a peptide derived from the type 1 repeats of TSP1 inhibits uptake of free fatty acids via CD36, which regulates eNOS, and inhibits downstream NO/cGMP signaling. The latter pathway requires CD47, but the mechanism remains unclear. One possibility is the lateral association of CD36 with an integrin that also associates with CD47.
