Current molecular model of signaling triggered by ultraviolet (UV)/riboflavin (MIRASOL) and UV/amotosalen (INTERCEPT) in platelets: UV can penetrate either directly or via surface/receptor proteins to activate p38MAPK kinase as one of the central players in the signaling cascade. Thus far it has been shown that p38 activation/phosphorylation (P-p38) is involved in regulating (1) degranulation, (2) release of free mitochondria, (3) the modulation of glycoproteins (GPs), (4) the expression levels of mRNAs and potentially protein synthesis, (5) microvesicle (MVs) release, and (6) the development of apoptosis via proapoptotic protein expression and caspase activation. This figure was modified from Ref. (150).
