How the Immune System Fights Disease

...hundreds of different chemicals, must be coordinated for the immune system to function smoothly. The immune system can mount a variety of responses to attack specific invader organisms. One of these responses is coordinated by T-helper cells (also known as T cells, T4 cells, or CD4 cells), which act as a kind of orchestra conductor. The T-helper cells tell other cells what to do when this response is triggered. We are interested in this...

Helper T-Cells

I've read that non-progressors produce certain type of "T helper Cells" in enough quantity so as to contain the virus, while progressors produce the same kind of "T helper Cells" but not in enough quantity. Has anybody tried yet to clone these...

Helper T Cell Rebound Following Chemotherapy

I recently completed a course of chemotherapy (2 cycles of Mytomycin C and 5FU) and radiation therapy (6 weeks) to treat squamous cell carcinoma. I have been HIV positive since 1985 and my CD4 levels have always been in the 500-600 range. ...
