Focusing on CD8: The "Other T Cell" in HIV Infection

Two types of T cells are critically important in HIV infection. Most discussion of these immune cells refers to the subset known as CD4+, which is the cell type counted during most patient visits to gauge when to start antiretroviral therapy and the... Read more »

Antiviral Activity of Virus-Specific CD8 T Cells Linked to Rate of CD4 T Cell Decline in HIV Infection

The extent to which virus-specific CD8 T cell responses contribute to control of viral load and prevention of disease progression in HIV infection has long been a subject of conflicting data and controversy. Early tests of the ability of CD8 T cells... Read more »

CD4+ Cell Count Decline in HIV-Infected Patients Is Growing More Rapid, Military Study Suggests

There's nothing like hearing the results of studies directly from those who actually conducted the research. In this interview, you'll meet one of these impressive HIV researchers and read her explanation of the study she presented at ICAAC/IDSA... Read more »

White Blood Cells during primary HIV infection

I am confused about this whole white blood cell thing. There are doctors who believe that during acute retroviral syndrome/primary HIV infections that white blood cell and lymphs are low, and others say that they would be high, which is true??...

Response from Bruce Dezube, M.D.

Harvard Medical School

I don't believe there is enough published to say definitively what happens to white cells during the acute retroviral syndroma/primary HIV infection. In general, in viral infections, the white blood cell count typically does go down; this is... Read more »

If HIV kills CD4 cells that present themselves, can high CD4 levels in first years of infection later result in faster progression to AIDS?

Dr. Holodniy, I am searching for the right words, but have an important question:It is often assumed that the more CD4 cells in a T cell subset, the better. But,in that the more CD4's that present themselves, the more for HIV to kill, could...

Response from Mark Holodniy, M.D., F.A.C.P., C.I.C.

Stanford University, School of Medicine

Not alot of studies on this issue. It is usually assumed that those infected people with such high CD4 counts, usually have low or undetectable viral loads, indicating an immune system with better capability to contain viral replication. It has... Read more »

The below is plagerized from Gallant ( the guru!)
I know that the present antiretroviral medications do not actually kill the virus.
However, if the medications inhibit the virus from reproducing, doesn't the virus die
