HIV Infected Adults In UCSF Study Show Evidence Of Thymus Activity

...on, the UCSF researchers used anantibody test that recognizes two markers on the surface of naive T cells. "The finding of thymus function in half of the patients raises the possibilitythat there are different mechanisms of HIV infection and different ways thatAIDS progresses," said McCune. "For those who have ...
