	Cell-mediated immunity - Wikipedia, the free encyclopedia
		Humoral immunity, for which the protective function of immunization could be found in the humor (cell-free bodily fluid or serum), 2.
		Cellular immunity, for which the protective function of immunization was associated with cells.
		Cell-mediated immunity is directed primarily at microbes that survive in phagocytes and microbes that infect non-phagocytic cells.

	Humoral immunity - Wikipedia, the free encyclopedia
		Humoral immunity (HIR) is the aspect of immunity that is mediated by secreted antibodies, produced in the cells of the B lymphocyte lineage (B cell).
		Humoral immunity refers to antibody production, and all the accessory processes that accompany it: Th2 activation and cytokine production, germinal center formation and isotype switching, affinity maturation and memory cell generation.
		This complex is moved to the outside of the cell membrane, where it can be recognized by a T lymphocyte, which compares it to similar structures on the cell membrane of a B lymphocyte.

	Cell-mediated immunity
		As was the case for activation of T cells where the signal derived from the TCR recognition of a peptide-MHC molecule was by itself insufficient for T cell activation, so too for the B cell.
		B cells (sometimes referred to as B-1 cells) form a population that is distinct from conventional B cells (sometimes referred to as B-2 cells).

	T-CMI
		Adaptive T cell-mediated immunity is driven by activation of T cells: cytotoxic T cells activated by endogenous antigen to kill infected cells, and helper T cells activated by exogenous antigen to stimulate macrophage killing of endosomal pathogens.
		Effector Cells in Adaptive Immunity
		Antigen activation of T cells occurs in the secondary lymphoid organs: Peyer's patches or tonsils for pathogens infecting mucosal tissues (respiratory, digestive, and urogenital tracts), draining lymph nodes for pathogens in the peripheral tissues, and the spleen for pathogens which are in the blood.

	Cell Mediated Immunity (Site not responding. Last check: 2007-10-30)
		T cells recognize their specific foreign protein or antigen only when it is presented on the surface of a body cell.
		In this case a pathogen enters the cell on the left and that cell moves foreign protein to its surface.
		A patrolling killer T cell recognizes and binds to that protein and releases perforin, a protein that ruptures the membrane of the infected cell.

	CND: Thymic Protein A - Introduction
		Cell Mediated Immunity employs an army of cells to attack and kill invaders.
		But because the thymus gland plays such a pivotal and important role in generating and regulating immune response, and we are all subject to atrophy of the thymus due to aging, disease and radiation, chemicals, chronic disease or trauma, etc., a large portion of immune dysfunction and/or suppression is due to thymus deficiency.

		Cell-mediated immunity is an immune response that does not involve antibodies but rather involves the activation of macrophages and NK-cells, the production of antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.

		The second half of the cell-mediated immune response is involved in rejection of foreign grafts and the elimination of tumors and virus-infected cells.
		Third, the CTL may release lymphokines and/or cytokines that interact with specific receptors on the target cell surface, causing internal responses that lead to destruction of the target cell.
		Once the target cell is recognized, killing occurs in a manner similar to that produced by the CTL.

	Immunity
		Cell mediated immunity where CD8+ T cells proliferate into 'killer' T cells and attack the invading antigen, using membrane bound antibodies for recognition of the antigen.
		Introduction: Cell mediated immunity does not usually treat the entire invading agent as an antigen, but the invader is first broken into small protein pieces and these invader peptides will be used to develop specific immunity.
		Antibodies as free proteins are not released in the cell mediated process, but rather T lymphocytes specific to these antigens will eventually recognize the antigenic part of the invader and stimulate phagocytes to destroy it.

		Another commonly used measure of cell-mediated immunity is the ability of T-lymphocytes to form in vitro rosettes of sheep erythrocytes surrounding T cells.
		However, a cell membrane site of action could explain the apparent transitory nature of the observed alterations in cell-mediated immunity, as well as the requirement for much larger concentrations of cannabinoids than those usually encountered during social use of marijuana.

	Cell-mediated immunity
		B cells occupy a unique position in immune responses because they express immunoglobulin (Ig) and class II MHC molecules on their cell surface.
		If one determinant is recognized by B cells (analogous to the hapten) and the same or different determinant is recognized by the helper T cells (analogous to the carrier), the same model applies.
		Some antigens activate both immature and mature B cells; other antigens activate only mature B cells and are thus not especially effective in infants where B cells are mostly immature.

	Cell Mediated Immunity
		In order for an immune response to be initiated in T cells, the T cell must first be presented with the foreign antigen along with a self antigen known as a major histocompatibilty protein.
		This complex is sent to the cell membrane.

	Humoral Immunity
		For immunity mediated by cytoxic T cells, an antigen is always a protein or a portion of a protein.
		For humoral immunity, the cells which are amplified (increased in number/stimulated to divide) are those which produce antibody, B cells.
		The existence of memory cells is the physiological manifestation of the priming of humoral immunity, i.e., for future recognition of specific antigens.

	Cell-mediated Immunity
		Antigens of the body's own cells are excluded so that the population of T-cells processed in this way is potentially capable of recognising 'self' and 'non-self' and only reacting against the 'non-self' molecules.
		Autoimmune diseases are those in which this recognition is defective, and certain of the body's cells may be recognised erroneously as 'non-self' and subsequently destroyed.
		Helper T-cells also known as T-helper cells, TH cells or T4 cells (these are the type of cell attacked by HIV).

	Cell-mediated Protection in Influenza Infection \| CDC EID
		The antiviral capacity of these virus-specific CD8+ cells is strongly dependent on their ability to migrate and localize to the lungs and infected airway epithelium (14), where they appear 5–7 days after infection (15).
		In the primary response, CD4+ T cells are not required for expansion or development of functional CD8+ CTL (27,29), which may in part result from the ability of influenza virus to directly activate dendritic cells, aiding in the development of CD8+ responses that substitute for functional CD4+ T cells (30).
		In mice that lacked CD4+ T cells during the primary response, the memory pool of CD8+ T cells was initially similar in size and functionality to that seen in wild-type mice but began to decline after longer intervals, leading eventually to the recrudescence of the infection.

		The Wistar Institute :: Suppression of Cell-Mediated Immunity by Down-regulation of Interleukin-12
		Description: The cytokine interleukin-12 (IL-12), which is produced during the immune response to a variety of stimuli, is critical for the development of cell-mediated immunity.
		However, inappropriate cell-mediated immune responses, often accompanied by over-expression of IL-12, have been identified as having a key role in the development of a variety of autoimmune disorders, such as rheumatoid arthritis, multiple sclerosis, graft-versus-host disease, diabetes mellitus, systemic lupus erythematosus (lupus), and Crohn's disease.
