GC formation requires specialized CD4 T cells, T-follicular helper (Tfh) cells, which localize to follicles and provide B cells with survival and differentiation signals that are essential for B-cell maturation into memory and long-lived plasma cells. Pathogenic autoantibodies in human and murine ...
Do helper T-cells cause B-cells to divide? How do helper T cells activate B cells? Do memory cells interact with helper T-cells? Are effector T-cells the same as helper T-cells? How is CTLA 4 activated in helper T-cells? What is the function of helper T cells?
How do T-cells activate B-cells to make antibodies in a process called immunological memory? Activated CD4 cells usually become: a. cytotoxic T cells b. Helper T cells c. B cells d. Plasma cells Cells that engulf foreign substances and help activate T cells are: A. T cells...

cellsthat help B cells, and not all follicular T cells are B cell helpers. Indeed some follicular T cells appear to be suppressive. Furthermore, Tfh cells evolve during an immune response and B cells that have recently bound antigen,germinal center(GC) B cells andplasmablastsinteract with ...
T cells recognizing tissue-restricted autoantigen is far from complete.14,15As a result, follicular activation of BDA-recognizing B cells may lead to a bona fide T-dependent autoreactive B cell response in normal animals. In the current study, we explored this hypothesis and showed that BDA-...

T helper (Th) cells are CD4+T cells that play a central role in the adaptive immune system, by facilitating the activity of other immune cells – especially antigen-presenting cells (APCs) such as B cells, macrophages, anddendriticcells – through the release of cytokines and chemokines. They...
