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...

t cell transfusion

I understand that HIV directly affects the helper t cell population. And that t cells are necessary to stimulate B cells, B cells to differentiate into plasma cells, finally secreting antibodies. Of course as time passes, the virus depletes the t...
