Immunological responses to protein, carbohydrate and lipid fractions of Nocardia asteroides in mice. 1985

R Gupta, and V Pancholi, and V K Vinayak, and G K Khuller

The protein, polysaccharide and phospholipid constituents of Nocardia asteroides have been partially purified and their immunogenicity studied in mice. Humoral and cellular immune responses were demonstrated against a crude cytoplasmic protein fraction (CPF). Two fractions of CPF were prepared on a Sephadex G-200 column; a high mol. wt fraction, fraction-1(F1) was capable of eliciting both types of immune responses, whereas fraction-2(F2) behaved more like a hapten. Phosphatides elicited only humoral responses whereas polysaccharides were non-immunogenic.

UI	MeSH Term	Description	Entries
D007114	Immunization	Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).

D007122	Immunoelectrophoresis	A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D007962	Leukocytes	White blood cells. These include granular leukocytes (BASOPHILS; EOSINOPHILS; and NEUTROPHILS) as well as non-granular leukocytes (LYMPHOCYTES and MONOCYTES).

D009616	Nocardia asteroides	A species of bacterium of the family NOCARDIACEAE, producing pulmonary infections in man.
D010743	Phospholipids	Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.	Phosphatides,Phospholipid
D011135	Polysaccharides, Bacterial	Polysaccharides found in bacteria and in capsules thereof.	Bacterial Polysaccharides
D002464	Cell Migration Inhibition	Phenomenon of cell-mediated immunity measured by in vitro inhibition of the migration or phagocytosis of antigen-stimulated LEUKOCYTES or MACROPHAGES. Specific CELL MIGRATION ASSAYS have been developed to estimate levels of migration inhibitory factors, immune reactivity against tumor-associated antigens, and immunosuppressive effects of infectious microorganisms.

D003378	Counterimmunoelectrophoresis	Immunoelectrophoresis in which immunoprecipitation occurs when antigen at the cathode is caused to migrate in an electric field through a suitable medium of diffusion against a stream of antibody migrating from the anode as a result of endosmotic flow.
