Interesting findings!

DH's immune system suppressed or at least hid the virus for a long time - eight or so years of false negative tests. (I'd love to get him into some of these tests - but then, geez, we might have to stay in one place for a while!)

My immune system is on overdrive, though - it goes crazy with the least little invasion of anything!

Isn't bio-chemistry just amazing????

Genetic Alert System Allows Some to Better Control HIV Than Others

Genetic Alert System Allows Some to Better Control HIV Than Others

The gene known as human leukocyte antigen C (HLA-C) is instrumental in alerting the immune system to HIVís presence, and variability in its levels in the body may help explain why some people can control the virus better than others, ABC Science reports. Following up on previous studies that identified an association between HLA genes and HIV disease outcome, researchers have now uncovered the mechanism behind this connection, publishing their findings in the journal Science.

Researchers studied more than 8,000 participants drawn from cohorts from Australia, Canada and the United States. They discovered that when HIV invades a cell, the HLA-C molecule alerts the immune system by sticking fragments of the virus onto the surface of the infected cell. The greater the levels of HLA-C in the body, the higher the likelihood that this process will successfully prompt the immune system to attack and kill the cell. Those with higher levels of HLA-C in the study maintained a lower viral load on average and were better buffered against immune damage.
