Enzyme Could Slow Part of the Aging Process in Astronauts -- And the Elderly

(Science Daily)  New research … suggests that a specific enzyme, called 5-lipoxygenase, plays a key role in cell death induced by microgravity environments, and that inhibiting this enzyme will likely help prevent or lessen the severity of immune problems in astronauts caused by spaceflight…
"The outcomes of this space research might be helpful to improve health in the elderly on Earth," said Mauro Maccarrone, Ph.D., a researcher involved in the work… "In fact, space conditions [cause problems that] resemble the physiological process of aging and drugs able to reduce microgravity-induced immunodepression might be effective therapeutics against loss of immune performance in aging people. 5-lipoxygenase inhibitors, already used to curb human inflammatory diseases, may be such a group of compounds."
