Photomicrography showing immunostaining for IL1-β in aorta of mice. Positive staining for IL1-β (arrows) increased in earlier period (30 minutes) in tunica adventitia (TA) and perivascular adipose tissue (PVAT) and in a long period (48 hours) in tunica media (TM), tunica adventitia and PVAT after angiotensin II injection (Magnification: 40x).
