Key result
Fluorescence imaging of rat mesenteric perivascular adipose tissue revealed sparse innervation by tyrosine hydroxylase-positive sympathetic nerves, which mostly tracked along small blood vessels.
Why the study?
The degree of innervation of PVAT by the sympathetic nervous system remained in question, prompting investigation into rat mesenteric PVAT, particularly in Dahl-salt sensitive rats.
Mesenteric perivascular adipose tissue in rats has sparse sympathetic innervation, suggesting limited direct neural control of individual adipocytes.
No takes yet. Share an insight, caveat, or question.
May indicate minimal sympathetic influence on mesenteric PVAT; leaves open its role in rodent vascular regulation models.
Jackson et al. (2025) studied Hypertension model (Dahl-SS rats). Tyrosine hydroxylase (TH) and CD-31 antibody labeling was evaluated on Degree of innervation of PVAT by TH-positive nerves. Fluorescence imaging of rat mesenteric perivascular adipose tissue revealed sparse innervation by tyrosine hydroxylase-positive sympathetic nerves, which mostly tracked along small blood vessels.
