| NK cell | Natural Killer cell |
|---|---|
| CNL | cardiolipin natural lecithin; chronic neutrophilic leukemia |
| DND | died a natural death |
| e | base of natural logarithms, approximately 2.7182818285; egg transfer; ejection; electric charge; ele... |
| LGL-NK | large granular lymphocyte-natural killer |
| antibodies, archaeal | Immunoglobulins induced by substances elaborated by archaea that have an antigenic activity. (12 Dec 1998) |
|---|---|
| antibodies, bacterial | Immunoglobulins induced by substances elaborated by bacteria that have an antigenic activity. (12 Dec 1998) |
| antibodies, bispecific | Antibodies, often monoclonal, in which the two antigen-binding sites are specific for separate antigenic determinants. They are artificial antibodies produced by chemical crosslinking, fusion of hybridoma cells, or by molecular genetic techniques. They function as the main mediators of targeted cellular cytotoxicity and have been shown to be efficient in the targeting of drugs, toxins, radiolabelled haptens, and effector cells to diseased tissue, primarily tumours. (12 Dec 1998) |
| antibodies, blocking | Antibodies that inhibit the reaction between antigen and other antibodies or sensitised T-lymphocytes (e.g., antibodies of the IgG class that compete with IgE antibodies for antigen, thereby blocking an allergic response). Blocking antibodies that bind tumours and prevent destruction of tumour cells by cytotoxic T-lymphocytes have also been called enhancing antibodies. (12 Dec 1998) |
| antibodies, catalytic | Antibodies that can catalyze a wide variety of chemical reactions. They are characterised by high substrate specificity and share many mechanistic features with enzymes. (12 Dec 1998) |
| antibodies, fungal | Immunoglobulins induced by substances elaborated by fungi that have an antigenic activity. (12 Dec 1998) |
| antibodies, helminth | Antibodies produced by human or animal cells following clinical or experimental exposure to parasitic helminth antigens. The IgE class of immunoglobulins is usually formed and released, but IgG, IgM, and IgA may also occur. (12 Dec 1998) |
| antibodies, heterophile | Antibodies elicited in a different species from which the antigen originated. These antibodies are directed against a wide variety of interspecies-specific antigens, the best known of which are forssman, hanganutziu-deicher (h-d), and paul-bunnell (p-b). Incidence of antibodies to these antigens--i.e., the phenomenon of heterophile antibody response--is useful in the serodiagnosis, pathogenesis, and prognosis of infection and latent infectious states as well as in cancer classification. (12 Dec 1998) |
| antibodies, monoclonal | Antibodies produced by clones of cells such as those isolated after hybridization of activated b lymphocytes with neoplastic cells. These hybrids are often referred to as hybridomas. (12 Dec 1998) |
| antibodies, neoplasm | Immunoglobulins induced by antigens specific for tumours other than the normally occurring histocompatibility antigens. (12 Dec 1998) |
| antibodies, protozoan | Antibodies produced by human or animal cells following clinical or experimental exposure to parasitic protozoan antigens. (12 Dec 1998) |
| antibodies, viral | Immunoglobulins produced as a response to viral antigens; includes all classes of immunoglobulins elicited by all viral components. (12 Dec 1998) |
| anticardiolipin antibodies | <immunology> Antibodies directed against cardiolipid, a phosphorylated polysaccharide ester of fatty acids found in cell membranes. Associated with immune-mediated illnesses, syphilis, and strokes; thought to be from a hypercoagulable state. (05 Mar 2000) |
| anti-microsomal antibodies | Anti-microsomal antibodies or anti-thyroid microsomal antibodies measure for the presence of antibody to thyroid microsomes. The anti-microsomal antibody or microsomal antibody test is used to diagnose conditions such as Hashimoto's thyroiditis and other autoimmune disorders. (27 Sep 1997) |
| anti-mitochondrial antibodies | A special serologic test that measures the level of antibodies to a particular portion of a cell (mitochondria). (27 Sep 1997) |
