CD4+ T cells, or helper T cells, are one type of lymphocyte that helps coordinate the immune response against infection and disease. They interact and activate other cells in the immune system.

In advanced HIV, when the CD4 count falls below 200, the CD4/CD8 ratio may fall below 0.3. When people begin taking antiretroviral treatment, their CD4 counts begin to rise. In the majority of people ...

The median CD4+ T-cell count among the patients was 80 cells per cubic millimeter.

Physician-scientists at Memorial Sloan Kettering Cancer Center (MSK) recently published two papers that advance the science of addressing critical issues with CAR T cell therapy in patients with ...

The freshly isolated PBMCs and primary CD4 + T cells were cultured in R10 medium and modified for NMN treatment experiments. For virus preparation and infection, the MOLT-4 CCR5 + cell line was ...

Certain levels of urinary CD4+ T lymphocytes in patients with ANCA-associated vasculitis have a 60% and 98% sensitivity and specificity, respectively, for predicting future renal flares.
