MARCO, His, Human

Macrophage receptor with collagenous structure (MARCO) is the predominant scavenger receptor for recognition and binding of silica particles by alveolar macrophages (AM). MARCO contributes to normal cholesterol uptake in macrophages, therefore, in the absence of MARCO, macrophages are more susceptible to a greater inflammatory response by particulates known to cause NLRP3 inflammasome activation and the effect is due to increased LMP.
