NIAID Scientists Identify New Cellular Receptor for HIV

A cellular protein that helps guide immune cells to the gut has been newly identified as a target of HIV when the virus begins its assault on the body's immune system, according to researchers from the National Institute of Allergy and Infectious... Read more »

Co-Receptor Conundrum

Since the late 1980s researchers have recognized that HIV isolates (viruses sampled from infected individuals) can be divided into one of two categories based on their ability to replicate in particular cells in the laboratory. Originally, a... Read more »

Safety Concerns Cast Shadow Over Novel Class of HIV Drugs

A new class of experimental HIV drugs, CCR5 receptor antagonists, is raising safety concerns. Designed to block a secondary but crucial doorway through which HIV enters cells in the body, the drugs would represent a shift in the fight against HIV,... 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...

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 »

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 »

co-receptors

i have recently read that hiv requires co-receptors to bind and be engulfed in the bloodstream. is there any evidence that these coreceptors may be absent from certain parts of the body - for example, parts of the skin compared to mucous membranes?...

Alternatively, another reason for infection via mucosal membranes is the large number of dendritic cells which process HIV and take it to the lymphnodes were rapid infection insues.... 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 »

How long have I had HIV?

Posted by redbull, 1 Reply
Do your #'s necessarily dictate how long you have had HIV? When I was diagnosed in 5/09 my cd4 was 94 and my VL was 400K. After being on atripla for 2 1/2 months my cd4 has jumped from 94-210 and my VL has dropped to only 500! My dr told me... Read more »
