(University of California - Santa Barbara) It's no secret that humans are having a huge impact on the life cycles of plants and animals. UC Santa Barbara's Steven D. Gaines and fellow researcher Dov Sax decided to test that theory by studying the world's far-flung islands.

ABC-transporters expressed on endothelial cell membranes efflux anti-HIV drugs
Tue, 26 Aug 2008 00:00:00 -0400
(Society for Experimental Biology and Medicine) Researchers at Tulane University Medical Center in New Orleans have discovered that drug-efflux pumps, belonging to the ATP-binding cassette transporter family, are constitutively expressed on vascular endothelial cells. The study has crucial implications in the persistence of sub-endothelial HIV reservoirs and will be important to the development of future therapies.
