HIV Drugs and the HIV Lifecycle

...virus. Thesteps HIV goes through to complete this process are as follows: Binding and Fusion HIV begins to enter a CD4 cell by binding (or attaching) itself to aspecific point, called a CD4 receptor, on the cell's surface. HIV must thenbind to a second co-receptor, either the CCR5 co-receptor or the CXCR4co-receptor. This allows the virus to join with the CD4 cell in a processcalled fusion. After fusion, HIV releases...

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...

...Hi,This is extremely interesting and important work. As an immunologist, I have advocated immune-based therapies for HIV treatment and, ultimately, cure since the early days of the epidemic. It's becoming clearer that despite truly remarkable... Read more »

A Thought that can change lives of Many HIV Patients

Can you guide me if following can be tried out on HIV patients, I have read a lot about mature T4 cells being replicated and grown outside the body.. Also I have read lot about defective co-receptors surface areas of T4 cells which do not allow HIV...

Did you mean HIV+?

Dear Dr. Holodniy,In your response to "What does CD4% mean" you write that "CD4% is the percentage of lymphocytes that are CD4+." I am scratching my head. Did you mean "HIV+" instead of "CD4+" or are there "CD4+" cells?Thank you.

...The answer is as I stated. CD4+ does NOT mean HIV infected. It means the cells are positive for having CD4 receptors on the cell surface. We can detect those receptors using special test reagents to determine Read more »
