CD47 deficiency can accelerate the progression of atherosclerosis, because CD47 deficiency and the loss of CD47-SIRPα interaction can cause the activation of T cells and dendritic cells and promote the expression of CD90 on NK cells and the production of IFN-γ, both of which can promote the formation of atherosclerosis [24]. This evidence concerns the gene THY1 and atherosclerosis.
