Figure 1

Schematic presentation of vascular wall composed of four tissue coats (tunicae): intima, media, adventitia, and adiposa. Arrows show that tunica media is a target for at least two vasorelaxing factors, endothelium-derived relaxing factor (EDRF) and adipocyte-derived relaxing factor (ADRF), respectively. Discontinuous black line positioned at the adventitia–media border illustrates perivascular nerves. Small-sized discontinuous black lines located in tunica adiposa indicate adipose nerves. Black granules (except those linked to arrows) illustrate immune cells – their association with nerves and adipocytes is also depicted. Modified from Ref. (14).
