Understanding CD4 Cells and CD4 Cell Tests

The Basics CD4 Count and HIV CD4 Count and HIV Treatment CD4 Cell Test The Bottom Line The Basics Your immune system protects your body by fighting germs and infections.White blood cells are an important part of your immune system. HIV infects and destroys a type of white blood cell called aCD4 cell (sometimes called a T-cell). When the immune system loses too many CD4 cells, it becomes weak and isunable to fight off germs. At...

T cell receptor

I know that at Boston Massachusetts General Hospital, they are ready to start a clinical trial to test a new chemio-molecules targeting specifically hiv infected cells, even the latent reservoirs.Do you think thatT-cell receptor may be used as a...

I am not aware of this trial so do not feel qualified to comment. I would suggest contacting Mass General to find out more and volunteerSorry not to be much useDr Moyle... Read more »

HIV or Meds causing abnormal CD4 receptors?

Dr. Boyle, Do all HIV positive folk have abnormal CD4 cell receptors? If so, is this caused by HIV infection or is it a side effect of meds? How do these abnormalities manifest themselves...do they cause symptoms or compromise immune...

Response from Brian Boyle, M.D., J.D.

Cornell University, Weill Medical College

Your question is a little confusing, but I'll try to give you the answer your looking for. CD4+ T cell deficits are not present in all patients with HIV, and the time to develop signficanty immunocompromise (low CD4+ T cells) may vary widely... Read more »

co-receptors

What are co-receptors? What is their significance in HIV infection?...

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

Stanford University, School of Medicine

Coreceptors are molecules on the surface of a cell, in addition to CD4, that HIV requires to lock onto a cell in order to gain entry and infect the cell.... Read more »

t4 receptors

Since t4 cells have receptors that hiv binds what does hiv have that causes this binding? Can any part of hiv surface bind to a t4 receptor? Is this binding process purely a chemical reaction? I have noticed over the last ten years when my lipids...

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

Stanford University, School of Medicine

Great questions. HIV has a very specific genetic sequence (and therefore structure) of its envelop protein that binds to the CD4 receptor in a tight lock-and-key way. The relationship between your lipids and HIV viral load is not directly related to... Read more »

What Is a T-Cell or CD4 Count?

Your T-cell count, also known as a CD4 count, reveals the number of T cells in your body. A T cell is a special kind of white blood cell, and the more you have, the stronger your immune system is. When you were infected... Read more »

IL-2 Induces Sustained CD4 Cell Increases in HIV-Infected Patients

By Deborah Mitchell

TORONTO, Sep 20 (Reuters Health) - The addition of recombinant interleukin-2 (IL-2) to an HIV antiretroviral therapy produces an increase in CD4+ T-cell counts,... Read more »

How Soon Should T-Cell Count Increase?

Posted by Anonymous, 5 Replies

I was infected in October 2003, diagnosed in December 2003, and went on Sustiva and Combivir December 30, 2003. My viral load went from an initial count of 125,000 down to 120, 2 weeks ago. Will probably be "undectable" soon. My question is, my... Read more »
