Effect of Renal Denervation, Central Blockade of AT1-R, or Inhibition of TNF-[alpha] on ISO-Induced Protein Expressions of ACE and TNF-[alpha] in the Brain.
The major findings of the present study are as follows: (1) RD significantly inhibited the decrease in BP in the development of ISO-induced HF and favorably altered autonomic regulation, including increase in HR variability and BRS and decrease in BP variability; (2) RD significantly inhibited ISO-induced increases in mRNA and protein expression of RAS components and PICs in the LT and PVN, two forebrain nuclei involved in regulation of BP and sympathetic activity; (3) central blockade of either AT1-R or TNF-[alpha] partially mimicked the beneficial actions of RD in the ISO-induced HF.
This depressor effect was attenuated by bilateral RD, but not by intracerebroventricular (icv) infusion of AT1-R antagonist irbesartan (Irbe) or TNF-[alpha] inhibitor etanercept (ENT) (a).
