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 ...

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 ...

Among treatment-naive adults living with HIV, CD4 to CD8 ratios do not differ significantly between those on dolutegravir ...

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 ...

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 ...

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 ...

Like an uninvited visitor tricking the host to gain entry, viruses induce ‘door-opening’ cellular processes like endocytosis by engaging the host cell’s surface proteins. Although not intended by the ...

CD4 counts show how strong your immune system is; lower counts mean a weaker immune response. The CD4 percentage shows what part of your white blood cells are CD4 cells and helps check how strong your ...
