Typically, these helper T cells are identifiable by their cell surface expression of the CD4 cell marker. Helper T cells are essential for activating B cells, macrophages, and natural killer cells, as well as other T cells. There are also three different types or subpopulations of effector CD4...
Monoclonal antibody to a helper T-cell marker (Leu-3) blocks HLA-DR dependent T-cell functionsAlthough the autologous mixed leukocyte reaction (AMLR) is usually defined as a proliferative response of T cells to autologous non-T cells, the reaction also results in the synthesis of immunoglobulin...

As their name suggests, T helper (Th) cells provide helper functions to other cells of the immune system—especially the antigen-presenting cells (APCs) such as macrophages, dendritic cells, and B cells—and are important for their activation and maturation. There ...
辅助性T细胞(Helper T cells, Th)在免疫反应中起到协调和增强其他免疫细胞活性的作用。它们通过分泌多种细胞因子,如IL-2、IFN-γ等,来激活其他T细胞亚型,特别是细胞毒性T细胞,并促进B细胞和NK细胞的活性。 比较与关联 细胞来源:效应T细胞和细胞毒性T细胞均源自胸腺,而辅助性T细胞则可能源自胸腺也可能源自脾脏或其他...
Although the autologous mixed leukocyte reaction (AMLR) is usually defined as a proliferative response of T cells to autologous non-T cells, the reaction also results in the synthesis of immunoglobulin (Ig) by B cells. The induction of Ig synthesis has an absolute requirement for helper (Leu ...
Plasticity between the Th17 and T regulatory lineages further complicates the use of CCR6 in combination with CD4 as the sole surface phenotyping markers for Th17 cells. In humans, the co-expression of CD39 with CD161, the human homologue ...
The findings indicate that lymphoma cells from mycosis fungoides or Sezary syndrome may express follicular center helper T-cell markers CD10, Bcl-6, and PD-1 and occasionally CXCL-13. The expression of these markers in some cases of mycosis fungoides/Sezary syndrome suggests follicular center ...
We show that ICB response correlated with the clonal expansion of intratumoral CXCL13+CH25H+IL-21+PD-1+CD4+ T helper cells (“CXCL13+ TH”) and Granzyme K+ PD-1+ effector-like CD8+ T cells, whereas terminally exhausted CD39hiTOXhiPD-1hiCD8+ T cells dominated in nonresponders. CD4+...
