	Immune System - NIAID Net News
		The two major classes of lymphocytes are B cells, which grow to maturity in the bone marrow, and T cells, which mature in the thymus, high in the chest behind the breastbone.
		T lymphocytes are responsible for cell-mediated immunity (or cellular immunity).
		A receptor on a circulating, resting cytotoxic T cell recognizes the antigen-protein complex and binds to it.

	Helper T cell
		cells secrete cytokines, proteins or peptides that stimulate other lymphocytes[?]; the most common is interleukin-2[?] (IL-2), which helps B cells differentiate into plasma B cells.
		cells are specific to the antigen they first encountered and can be called upon during the secondary immune response[?].
		cells have present on the cell surface the protein CD4[?], which is attracted to portions of the Class II MHC molecule.

	T helper cell Summary
		T cells are generally treated as having a pre-defined role as helper T cells within the immune system, although there are known rare exceptions.
		T cells, the TcR has an affinity with Class II MHC, and it is believed that CD4 is involved in determining this affinity during maturation in the thymus.
		Helper T cells are capable of influencing a variety of immune cells, and the T cell response generated (including the extracellular signals such as cytokines produced) can be essential for a successful outcome from infection.

	Immune-System-Plus
		T cells (thymus cells) move from the bone marrow and are processed in the thymus, a pyramid-shaped organ located beneath the breastbone.
		T cells are involved in cellular immunity, as their immunity response takes place directly between the T cells and the antigens.
		Helper T cells that encounter IL-1 and fragments of antigens transform into cells called lymphoblasts, which then secrete a variety of interleukins that are essential to the success of the immune response.

	BioCarta - Charting Pathways of Life
		T helper cells play an essential role coordinating the activities of other parts of the immune system, including B cells, cytotoxic T cells, macrophages and other cells.
		The crucial nature of helper T cells in the normal immune response is demonstrated by the severe immune deficiency associated with the HIV-induced helper T cell depletion.
		Like all T cells, helper T cells express T cell receptors complexed with the CD3 proteins that are responsible for the recognition and response of the cell to specific antigens (see “T Cell Receptor Signaling Pathway”).

	Generex.nu » T Helper Cell
		A T helper cell (sometimes also known as effector T cells or TH cells) are a sub-group of lymphocytes (a type of white blood cell or leukocyte) that play an important role in establishing and maximising the capabilities of the immune system.
		They are essential in determining B cell antibody class switching, in the activation and growth of cytotoxic T cells, and in maximising bactericidal activity of phagocytes such as macrophages.
		CD4+ T cells are believed to have a pre-defined role as helper T cells within the immune system, although there are rare exceptions.

	How the Immune System Works
		Hence, among the T cells and the B cells, there must be many different receptors, receptors specific for the antigens of each and every different disease—but each individual T cell and B cell has receptors that are specific for only one disease antigen.
		The helper T cells (one of the three major T cells) are crucial.
		Triggered by the presence of enemy antigens, the helper T cells by chemical signals (proteins called lymphokines) rally the troops of the immune system and increase their ranks by the millions.

	Helper T Cells
		Th2 cells are produced when DC2-type dendritic cells present antigen to the T cell's receptor for antigen (TCR) and, presumably, one or more paracrine stimulants.
		It is secreted by epithelial cells and phagocytic cells in regions where allergic reactions are occurring.
		Situated in the skin and the lining of the GI tract, Th17 cells are positioned to attack bacteria on those surfaces.
