Renal adaptation during hibernation

Am J Physiol Renal Physiol. 2013 Dec 1;305(11):F1521-32. doi: 10.1152/ajprenal.00675.2012. Epub 2013 Sep 18.


Hibernators periodically undergo profound physiological changes including dramatic reductions in metabolic, heart, and respiratory rates and core body temperature. This review discusses the effect of hypoperfusion and hypothermia observed during hibernation on glomerular filtration and renal plasma flow, as well as specific adaptations in renal architecture, vasculature, the renin-angiotensin system, and upregulation of possible protective mechanisms during the extreme conditions endured by hibernating mammals. Understanding the mechanisms of protection against organ injury during hibernation may provide insights into potential therapies for organ injury during cold storage and reimplantation during transplantation.

Keywords: electrolytes; hibernation; kidney; metabolism; torpor.
