these diseases, and will include a search for any genes that predispose strongly to illness. The volunteers taking part in the project will have the benefit of a health check and will also be contributing to improving the health of the community in O...
T cell's memory may offer long-term immunity to leishmaniasis
...f cutaneous leishmaniasis, which infects the skin, causing
scarring boils, and 500,000 new cases of visceral leishmaniasis, which infects internal organs, causing
death if left untreated. Particularly vexing to researchers has been the fa...
Cooperation to create a new tuberculosis vaccine

Researchers find protein that makes long-term memory possible
...itters. A neuron generates an electrical impulse, causing
the cell to release its neurotransmitters. The neurotransmitters, in turn, bind to special sites, or receptors, on nearby neurons. The recipient neurons then generate their own electrical impulses and release their own neurotransmitters, triggering...
