Dual role of CD-36—TSP-1 interaction in inflammation. Expression of CD36 is positively regulated by PPARγ and negatively regulated by TGFβ. As an integral membrane protein, CD36 binds many ligands including TSP-1. The CD36-TSP-1 interaction involves conformational changes in TSP-1. This interaction mediates apoptotic effects via the CD47-dependent pathway, which has multiple effects. The CD36-TSP-1 interaction can also activate macrophage TGFβ1 and the NFκB pathway *[98, 99], **[100–102], †[100], ‡[103].
