Polyclonal antibody production induced by parotid protein and its active glycopeptide in mouse and human lymphocytes. 1983

S Ishizaka, and I Sugawara

Parotid protein (extracted from bovine parotid gland), one parotid subunit, and the active fragment (FrAA-1) induced polyclonal IgM, IgG, and IgA antibody production in murine spleen cells in vivo and in vitro. The parotid subunit also elicited polyclonal IgM antibody responses in immune defective CBA/N and LPS nonresponder C3H/HeJ mouse. When one carbohydrate residue in the subunit was removed by treatment with mixed galactosidase, the ability to generate nonspecific responses was markedly reduced. In human peripheral lymphocytes, the parotid subunit and FrAA-1 induced considerable polyclonal IgM antibody production. The subunit was not toxic to human lymphocytes. Therefore, it seems possible that parotid protein could be applied to immunopharmacological therapy for conditions such as immunodeficiency.

UI	MeSH Term	Description	Entries
D007120	Immunochemistry	Field of chemistry that pertains to immunological phenomena and the study of chemical reactions related to antigen stimulation of tissues. It includes physicochemical interactions between antigens and antibodies.
D007136	Immunoglobulins	Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.

D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008815	Mice, Inbred Strains	Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations, or by parent x offspring matings carried out with certain restrictions. All animals within an inbred strain trace back to a common ancestor in the twentieth generation.

D011506	Proteins	Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.
