Mosquitoes are more attracted to individuals infected with malaria

...Koella and colleagues have shown that the parasite itself manipulates the biting behaviour of the mosquito vector when it is ready for a new host. Such manipulation could have a profound effect on the epidemiology of disease and, if it is not considered, could lead to severe biases in the estimates of the i...

The key to the researchers?finding was the interaction between the Mule enzyme and a major player in cell death, the protein Mcl-1. Dr. Wang said that while there are many possible routes a c...

OHSU researchers discover potential mechanism to repair brain damage linked to Multiple Sclerosis
