CD4 Cell Tests

...T-8 cells (CD8+) are "suppressor" cells that end the immune response. CD8 cells can also be "killer" cells that kill cancer cells and cells infected with a virus. Researchers can tell these cells apart by specific proteins on the cell surface. A T-4 cell is a T-cell with CD4 molecules on its surface. This type of T-cell is also called "CD4 positive," or CD4. Why Are CD4 Cells Important in HIV? When HIV infects humans, the cells it...

early treatment and hiv-specific T cells

Dear Dr. Young,I have read about the studies of Walker et al. with great interest, and I think their data encourages earliest-possible treatment.One of the easy-to-grasp aspects is that it simply disallows the virus to satuarate all possible...

...Thanks for your thoughtful question.I think that the simple answer is that while there is a steady production of T cells, these T cells do not represent a new set of cells, but rather clones of preexisting cells. The immunological diversity or Read more »

T cell activity in lab setting

Hi, Dr. H, Thanks for this great forum. Is it possible to be HIV positive and for one's T cells to not be activated at all...or do all HIV poz folks have distinctive T cell activation when analyzed in the lab?
