A review found that CD4/CD8 ratio could be used as a prognostic marker for mortality in patients with HIV, though future studies need to be done to confirm these findings. Clinical practices can ...

The drug had minimal effect on the low CD4-cell counts of immunologic nonresponders. Most HIV-infected patients with adequate virologic suppression on antiretroviral therapy (ART) will eventually ...

A new CD4 testing system, the BD FACSPresto Near Patient CD4 Counter system (BD Biosciences), enables patients to monitor their HIV/AIDS, potentially reducing the probability of transmitting the ...

A panelist discusses how CD4 counts serve as measures of immune system status that typically increase by about 200 in the first year of antiretroviral therapy. Although there can be laboratory ...

BD Biosciences, part of Becton, Dickinson and Company (BD), provides a Near Patient CD4 Counter system for HIV/AIDS patients in the country. Known as BD FACSPresto, the Near Patient CD4 Counter system ...

A study led by the Peter Doherty Institute for Infection and Immunity (Doherty Institute) has found that CD4 + T cells, traditionally called 'helper T cells' for their role in aiding the activation of ...

You have full access to this article via your institution. The initial stage of HIV-1 infection is followed by an asymptomatic period that can last for years before disease progresses and results in ...

Immunocompromised populations develop a lower immunogenic response to COVID-19 vaccines, leaving them at a higher risk of severe disease, hospitalization, and death. Patients with HIV who have low ...

T cells play important roles in helping to fight infections and cancers—and they can also drive autoimmune diseases. Now researchers at La Jolla Institute for Immunology (LJI) have discovered new ...

Medical researchers have found that the CD4 surface protein, which is used by HIV and SIV as the receptor to enter immune cells, is highly variable among wild chimpanzees. Understanding how these ...
