T cells are grouped into a series of subsets based on their function. CD4 and CD8 T cells are selected in the thymus, but undergo further differentiation in the periphery to specialized cells which have different functions. T cell subsets were initially defined by function, but also have associated gene or protein expression patterns.
A lymphocyte is a type of white blood cell (leukocyte) in the immune system of most vertebrates. [1] Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for humoral, antibody-driven adaptive immunity), [2] [3] and innate lymphoid cells (ILCs; "innate T cell-like" cells involved in mucosal immunity and homeostasis), of which natural killer cells are an ...
Previous attempts to quantify antigen-specific T-cells involved the less accurate limiting dilution assay, which estimates numbers of T-cells at 50-500 times below their actual levels. [ 7 ] [ 8 ] Stains using soluble MHC monomers were also unsuccessful due to the low binding affinity of T-cell receptors and MHC-peptide monomers.
Follicular helper T cells (also known as T follicular helper cells and abbreviated as T FH), are antigen-experienced CD4 + T cells found in the periphery within B cell follicles of secondary lymphoid organs such as lymph nodes, spleen and Peyer's patches, and are identified by their constitutive expression of the B cell follicle homing receptor CXCR5. [1]
V(D)J recombination (variable–diversity–joining rearrangement) is the mechanism of somatic recombination that occurs only in developing lymphocytes during the early stages of T and B cell maturation. It results in the highly diverse repertoire of antibodies/immunoglobulins and T cell receptors (TCRs) found in B cells and T cells, respectively.

The assay set-up consists of purifying responder lymphocytes from peripheral blood, thymus, lymph nodes or spleen and co-culturing with stimulator cells. Stimulator cell populations that also contain T-cells (Two way mixed lymphocyte reaction) will replicate in the presence of the Responder cells, therefore for a One way mixed lymphocyte reaction, stimulator cells are prevented from ...
