molecular mechanisms

(University of Washington) A study of host-pathogen responses in tuberculosis elucidates molecular mechanisms of antibiotic tolerance in tuberculosis and further suggests a strategy for shortening curative therapy (currently six months) using a class of drugs -- efflux pump inhibitors-- that are already approved for treating high blood pressure and angina, and available for use in people.

Although acupuncture has long been used to treat pain, the underlying cellular and molecular mechanisms are not fully understood.

The process appears to involve the brain's ability to produce opioids (pain-reducing chemicals) that bind to neurons in distinct regions of the brain, and the ability of neurons to produce receptors for these endogenous opioids—specifically, mu-opioid receptors (MORs).
