a form of immunity where antibodies have no role or play only a secondary role. It includes the processes where cytotoxic cells kill pathogens.
lymphocytes bind to the surface of other cells that display the antigen and trigger a response; the response may involve any of the white blood cells, called leukocytes
An immune system capability that works through the production of cells that destroy infected cells in the body..
Immune responses mediated by T lymphocytes.
Immunity dependent upon T-cells' recognition of an antigen and their subsequent destruction of cells bearing the antigen
This branch of the immune system exists primarily to deal with viruses that are more insidious than bacteria because they invade the host (e.g., human) cells where they can hide from the antibody-making cells of the immune system. With this system, the reaction to foreign material is performed by specific defense cells, such as killer T cells, macrophages, and other white blood cells rather than by antibodies.
The immune response mediated by T lymphocytes. Cell-mediated immunity is responsible for allograft rejection, delayed hypersensitivity, and defense against viruses.
the process in which the T lymphocytes interact with the microorganisms cell-to-cell and destroy them.
Immunity that results from T-cells contacting foreign or infected cells and destroying them.
Resistance to disease through the activities of sensitized T cells that destroy antigen-bearing cells by direct contact or through the release of lymphotoxins; also called cellular immunity.
(sell MEE-dee-ay-ted ih-MYOO-neh-tee) Immune response that involves effector T cells and no production of antibodies. This type of immunity is responsible for allograft rejection, delayed hypersensitivity and defense against viral infection, certain parasites and diseases. Also called cellular immunity or a T-cell response.
(Also called cellular immunity) The branch of the immune system that targets host cells infected with microorganisms such as viruses, fungi, and certain bacteria. It is coordinated by helper T-cells and CTLs.
part of the immune system in which specific immune system cells, such as cytotoxic T cells, directly attack infected cells.
Immune response that involves T-cells and not B-cells with antibody production (see humoral immunity). This type of immunity is responsible for tissue transplant rejection, delayed hypersensitivity and in defense against viral infection and intracellular protozoan parasites.
immune response mediated by T lymphocytes (T cells)
Immunity, which is dependent on the sensitisation of certain white blood cells, rather than antibodies.
When the immune system fights infection via cell to cell combat rather than antibody contact. The defense cells used in cell-mediated immunity are killer T-cells, macrophages, and other white blood cells. This is called Cellular Immunity.
The immunity that is the result of either special lymphocytes directly killing the foreign invader, or lymphocytes (T cells) releasing special chemicals which activate macrophages to kill the invader. Compare with 'humoral immunity.'
A defence mechanism involving the coordinated activity of two subpopulations of T lymphocytes, helper T4 cells and killer T8 cells. Helper T cells produce substances that stimulate and regulate other cells of the immune system.
The immune response coordinated by helper T cells and CTLs. This branch of the immune system targets cells infected with microorganisms such as viruses, fungi and certain bacteria.
Immune reaction directed against body cells that have been infected by viruses and bacteria; controlled by T cells.
part of the immune system responsible for direct attack foreign material without using proteins (antibodies), consists mainly of T-lymphocytes, killer cells, and macrophages.
describes any adaptive response in which antigen-specific T cells have the main role. It is defined operationally as all adaptive immunity that cannot be transferred to a naïve recipient with serum antibody.
The type of immunity that functions in defense against fungi, protists, bacteria, and viruses inside host cells and against tissue transplants, with highly specialized cells that circulate in the blood and lymphoid tissue.
Immunity in which the predominant role is played by T lymphocytes.
Acquired immunity as a result of T-lymphocytes and activated macro phages.
Cell-mediated immunity is that component of immunity in which specially sensitized lymphocytes (T cells) attach to antigens to destroy them.
Immune reaction mediated by T cells; in contrast to humoral immunity, which is antibody mediated. Also referred to as delayed-type hypersensitivity.
Immunity resulting from activation of sensitized T cells, (as opposed to humoral immunity, which is based on B-cells).
Using cells to activate antibodies to fight against foreign organisms.
Immunity which involves the T lymphocytes to fight intracellular infection and is involved in transplantation rejection and delayed hypersensitivity.
Cell-mediated immunity, also known as delayed-type hypersensitivity (DTH), is an immune response that does not involve antibodies but rather involves the activation of macrophages, natural killer cells (NK), antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen. Historically, the immune system was separated into two branches; 1. Humoral immunity, for which the protective function of immunization could be found in the humor (cell-free bodily fluid or serum), 2.
