Defensins Ward Off HIV In Two Ways

... have molecules called CD4 on their exterior. They help orchestrate the body's response to viruses and therefore play important roles in the immune system. The researchers show that alpha-defensin-1 fights HIV in two different ways. Without serum (the watery portion of blood that remains when blood cells...

NSAID drug protects against intestinal tumors in mice, despite poor diet and gene losses

... with sulindac, an agent they had previously found help suppress tumor formation. To their surprise, none of the knock-out mice developed cancer. "To us this means that as long as an animal can activate the p21 gene, this can have an overriding affect on suppressing tumor formation caused by either loss ...
