Omega fatty acid balance can alter immunity and gene expression

For the past century, changes in the Western diet have altered the consumption of omega-6 fatty acids (w6, found in meat and vegetable oils) compared with omega-3 fatty acids (w3, found in flax and fish oil). Many studies seem to indicate this shift has brought about an increased risk of inflammat...

Survivors of 1918 flu pandemic protected with a lifetime immunity to virus

HIV accessory protein disables host immunity via receptor-protein intermediary

Researchers at the University of Pennsylvania School of Medicine discovered that an HIV-1 accessory protein called Vpr destroys the host cell's ability to survive by binding to a host receptor. This, in turn, keeps an important enzyme from activating the cell's immune system. These findings refine ...

New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

New insights by Duke University Medical Center researchers as to how HIV evades the human immune system may offer a new approach for developing HIV vaccines.
