Bee Venom Protects Kidneys From Cancer Drug Toxicity

I've always said that bee stings were like booster shots. This is seriously good news for those receiving cancer treatment - added protection for kidneys against negative side effects of potent drugs. If you're also in that situation, taking propolis is highly recommended, as it has a protective effect on the liver against toxins, not to mention its immune system supportive activity... 

Bee Venom Mitigates Cisplatin-Induced Nephrotoxicity by Regulating CD4(+)CD25(+)Foxp3(+) Regulatory T Cells in Mice
Evid BasedComplement Alternat Med, 2013, Vol 2013, Art ID 879845

Cisplatin is used as a potent anticancer drug, but it often causes nephrotoxicity. Bee venom (BV) has been used for the treatment of various inflammatory diseases, and its renoprotective action was shown in NZB/W mice. However, little is known about whether BV has beneficial effects on cisplatin-induced nephrotoxicity and how such effects might be mediated. In the present study, the BV-injected group showed a significant increase in the population of Tregs in spleen. Although there was no significant difference in the numbers of Tregs 3 days after cisplatin injection between the BV- and PBS-injected groups, more migration of Tregs into the kidney was observed 6 hours after cisplatin administration in BV group than in PBS group. In addition, BV-injected mice showed reduced levels of serum creatinine, blood urea nitrogen, renal tissue damage, proinflammatory cytokines, and macrophage infiltration into the kidney 3 days after cisplatin administration. These renoprotective effects were abolished by the depletion of Tregs. The anticancer effect of repeated administrations of cisplatin was not affected by BV injection.
These results suggest that BV has protective effects on cisplatin-induced nephrotoxicity in mice, at least in part, through the regulation of Tregs without a big influence on the antitumor effects of cisplatin.
