Proliferation cues ‘natural killer’ cells for job change

Why would already abundant ‘natural killer’ cells proliferate even further after subduing an infection? It’s been a biological mystery for 30 years. But now Brown University scientists have an answer: After proliferation, the cells switch from marshaling the immune response to calming it down. The findings illuminate the functions of a critical immune system cell important for early defense against disease induced by viral infection.

Infectious fungus, thought to be asexual, isn’t

Candida troCandida TropicalisCandida Tropicalispicalis turns out to have sex, making it the second medically important member of the genus to be capable of mating. Sex may improve the survival of the species, particularly when it’s under pressure. It may also mean the species can a chieve greater virulence or drug resistance more quickly than previously thought.  Credit: David Orenstein, December 5, 2011

A first-year fast track to the excitement and challenge of science

In their first semester at Brown, students have had the chance to discover their own species, name it, examine  its DNA and walk the walk of real scientists. Even as the students toiled against the clock one No vember day, they readily took the time to praise the experience. Credit: David Orenstein, November 29, 2011
