CCR2 and cardiomyopathy: It is of interest that, among the similar sub-populations corresponding to the resident (CCR2−MHChi) or recruited (CCR2+) species, also identifiable in human cardiomyopathy samples (135), the monocyte-dependent CCR2+ population shows proinflammatory features and its abundance is associated with persistent systolic dysfunction in patients undergoing LV-assisted device unloading (125).
