Immunological studies of acetylcholine receptors

Journal of Supramolecular Structure, 1976
AbstractImmunochemical techniques for the study of acetylcholine receptors are described. Immunization of rabbits, rats, guinea pigs, and goats with acetylcholine receptor protein purified from Electrophorus electric organ tissue results in muscular weakness and death due to impaired neuromuscular transmission.

Chick oviduct progesterone receptor: structure, immunology, function

Molecular and Cellular Endocrinology, 1984
Analysis of the purified chick oviduct progesterone receptor using biochemical and immunological approaches indicates that while the 'activated' receptor ('4S') is a mixture of two progestin-binding polypeptides, 'A' (Mr approximately 79 kDa) and 'B' (Mr approximately 110 kDa), the non-activated receptor ('8S') is a population of complexes containing a

Three immunologically similar atrial natriuretic factor receptors

Molecular and Cellular Biochemistry, 1992
One of the atrial natriuretic factor (ANF) receptors is a 180 kDa protein (180 kDa mGC) which possesses the extraordinary characteristic of being bifunctional: it is both a receptor and a guanylate cyclase. In addition to the 180 kDa mGC, there exists another 120-130 kDa protein which is also bifunctional and a 120 kDa disulfide-linked dimeric cell ...

Chemokine Decoy Receptors: New Players in Reproductive Immunology

Immunological Investigations, 2008
Chemokines are multifunctional molecules with roles in leukocyte trafficking and developmental processes. Both fetal and maternal components of the placenta produce chemokines, which control leukocyte trafficking observed in the placenta. Thus, chemokines play roles in the balance between protection of the developing embryo/fetus and tolerance of its ...

Immunology of bile acids regulated receptors

Progress in Lipid Research
Bile acids are steroids formed at the interface of host metabolism and intestinal microbiota. While primary bile acids are generated in the liver from cholesterol metabolism, secondary bile acids represent the products of microbial enzymes. Close to 100 different enzymatic modifications of bile acids structures occur in the human intestine and ...

Somatostatin receptor expression in clinical immunology

Metabolism, 1996
Specific somatostatin receptors (ssts) have been described in normal and tumor tissues and identified on more than 95% of normal mitogen-activated human peripheral lymphocytes. Somatostatin may modulate the immune response by a variety of mechanisms, most of which are inhibitory, sst scintigraphy in patients with immune-mediated diseases revealed sst ...

Fc Receptors in Mucosal Immunology

2015
Immunoglobulin A (IgA) is the most prevalent antibody class at mucosal surfaces. In addition to protecting mucosal surfaces by preventing invasion of pathogens, IgA can interact with multiple IgA receptors by binding to the Fc tail, carbohydrate side chains, or accessory molecules. The best characterized IgA Fc receptor is FcαRI (CD89), which acts as a

Is schizophrenia an immunologic receptor disorder?

Medical Hypotheses, 1983
A model is proposed for an autoimmune etiology for schizophrenia. We propose that schizophrenia is a syndrome (not a disease). We suggest that autoantibodies (and/or cell-mediated immunity) directed against autologous neurotransmitter receptors are responsible for the ebb and flow of psychotic symptomatology.

Immunology of the Nicotinic Acetylcholine Receptor

1979
The classical surface antigens of Enterobacteriaceae: 0, K, and H antigens have been studied extensively in the past and have provided a basis for the taxonomy of this family (Kauffmann, 1966, 1975). In comparison to the vast knowledge accumulated on the structure, localization, genetic determination, and biologic effects of O and K antigens (Weinbaum ...

Immunological aspects of acetycholine receptors

Trends in Neurosciences, 1983
Abstract Monoclonal antibodies raised against purified acetycholine receptor (AChR) can be used as probes for defining its structure and function, and, indirectly, for defining the binding sites of antibodies from patients with the muscle disease myasthenia gravis (MG).
