WebTLRs are also involved in T-cell development and can reprogram Treg cells to become helper cells. T cells consist of various subsets, that is, Th1, Th2, Th17, T follicular helper (Tfh), cytotoxic T lymphocytes (CTLs), regulatory T cells (Treg) and these originate from thymic progenitor thymocytes. T follicular helper cells (Tfh) are a specialized subset of CD4 + T cells that were first identified in the human tonsil. They play a critical role in protective immunity helping B cells produce antibody against foreign pathogens. Tfh are located in secondary lymphoid organs (SLOs), including the tonsil, spleen and lymph … See more Tfh play an essential role in the formation of germinal centres (GCs), which are distinct structures that form within the B cell zones of SLOs … See more Tfh are defined by expression of the transcription factor, B cell lymphoma 6 (Bcl6) and a number of cell surface markers including … See more In addition to Tfh expressing the CD4 co receptor, a population of T cells expressing the CD8 co-receptor have been found to express CXCR5, PD1 and Bcl-6. They have been … See more Tfh function has been shown to be dysregulated in a number of diseases of excessive or insufficient antibody production. Circulating Tfh numbers have been shown to … See more paint resize image without losing quality
