Ancient immune defense mechanism is no match for HIV-1

...chanism HIV-1 uses to protect itself provides some critical insight into a potential vulnerability within the HIV-1 molecule. Identification of what might be a long sought after weakness in the virus may have application for rational design of future anti-HIV-1 therapies. The study is published in the May iss...

Precise Timing Enabled Pig-to-rat Transplants To Cure Diabetes

...earned that a temporal "window of opportunity" was critical to their earlier successes in treating diabetic rats with embryonic pig tissues. In those experiments, published in 2004, researchers were surprised to find that they didn't have to give anti-rejection drugs to diabetic rats treated with embryonic p...

Mutation in clams protects against paralytic shellfish poisoning but raises human health risk

...pass through the membrane. Regulation of sodium is critical to nerve cell function. Without the mutation, the PSP toxins can bind to the sodium channel, shutting down the nerve and leading to paralysis. The toxin acts like a cork in a bottle, preventing sodium ions from flowing through the membrane, says Con...
