These individuals may appear to have no CD4 + cells when in fact they have normal numbers of T-helper cells if identified by other monoclonal antibody markers (e.g. Leu 3a). Consequently, OKT4 monoclonal antibodies are no longer utilized for CD4 cell count determinations. The initial CD4 +...
Intratumoral dendritic cell–CD4+ T helper cell niches enable CD8+ T cell differentiation following PD-1 blockade in hepatocellular carcinoma Assaf Magen, Pauline Hamon, Nathalie Fiaschi, Brian Y. Soong, Matthew D. Park, Raphaël Mattiuz, Etienne Humblin, Leanna Troncoso, Darwin D...
The reason for observedchronic immune activation, low CD4+ T cell count and inverted CD4/CD8 ratioin the African population remains poorly understood. Nonetheless, we noted that it isnot genetic in origin, but something that is acquired during life(9, 15, 17). Chronic immune activation(长期/...
In addition, CD4+ T-cell and NK cell but not CD8+ T-cell counts were lower in ventilated chil- dren than in nonventilated children. Combination of IL-8, CCL-5, and CD4+ T-cell Count Discriminates Severe RSV Infection From Mild RSV Infection Clinical and inflammatory parameters that were...

Naive T cells, which develop in the thymus, are the common precursors of helper T cells that have not yet encountered antigen. In naive cells, full T-cell activation (Figure 1) requires costimulatory receptors, including CD4+ or CD8+, together with LFA1, CD28, and ICOS. All of these rec...

Single-cell and chromatin accessibility profiling reveals regulatory programs of pathogenic Th2 cells in allergic asthma Pathogenic T helper type 2 cells (pTh2) are involved in allergic asthma and secrete high levels of IL-5 and IL-13. Here, using HDM challenged mice and developing an in vitr...
cell lung carcinoma. We define this clonally expanded, tumor-specific and conserved T-cell subset as T-helper tumor (Tht) cells. Reconstitution of Tht cells in vitro and in an ovalbumin-specific αβ TCR CD4+T-cell mouse model, shows that the Tht program is primed in tumor-draining lymph...
