U.S. scientists say they have determined how a deadly fungus microbe -- Cryptococcus neoformans -- evades the human immune system and causes disease. Albert Einstein College of Medicine researchers said their findings may help scientists develop new therapies or vaccines against fungal infections, such as those that occur in AIDS and transplant patients who must take lifelong immunosuppressive therapy. Scientists have known the capsule surrounding C. neoformans is essential to its ability to...
