Dendritic cells offer new therapeutic target for drugs to treat MS and other autoimmune disease

... Center have found that a gene pathway linked to a deadly form of leukemia may provide a new way to treat autoimmune diseases, including multiple sclerosis. Their tests in cell cultures and mice suggest that blocking the pathway by interfering with a blood cell growth gene, known as FLT3, targets an immune ...

Researcher says flu responders can learn from 1918 epidemic

...winter may bring with it one of the most sweeping, deadly outbreaks of killer flu that the world has ever seen.

In 1986, a CO2-driven eruption in Cameroon's Lake Nyos killed some 1,700 people, as well as animals in the area; two years earlier, a smaller release of CO2 from Lake Monoun in the same country resulted in 37 human deaths. The death...

Researchers develop new method to help find deadly malaria parasite's Achilles heel

The most deadly malaria parasite has protein 'wiring' that differs markedly from the cellular circuitry of other higher organisms, a finding which could lead to the development of antimalarial drugs that exploit that difference. Researchers at UCSD have discovered t...
