Emerging role of pericytes in therapy of cardiovascular diseases

Pericytes are mural vascular cells covering microvascular capillaries, where they contribute to the formation, maturation, maintenance, stabilisation and remodelling of vasculature. They actively interact and communicate with other cells to maintain the capillary structural integrity, vascular permeability and blood flow. Pericytes are crucial participants in the physiological and pathological processes of cardiovascular disease. In this review, we summarise recent data regarding pericyte metabolism, trans-differentiation, angiogenesis and immunomodulation in connection with different cardiovascular pathologies. Further, we discuss an application of pericytes as a new cell therapy approach to treat coronary artery disease, congenital heart disease, atherosclerotic plaques calcification and calcific valvular heart disease in different in vivo animal models and in vitro studies. Also, we discuss different methods and pharmacological therapies for CVDs treatment with pericyte-mediated effects. Finally, we present a comprehensive overview of the role of pericytes in CVDs and as a pharmacological target for different novel drugs and techniques and highlight the potential application of pericytes to treat CVDs.
