title: [M-cholinergic receptors of B-lymphocytes during immune response in mice].
abstract: The number of M-cholinergic receptors on spleen B-lymphocytes of CBA mice was determined using radioactive blocker 3H-Quinuclidinil benzilate. 3 and 4 days after the animals' immunization with ovalbumin the number of M-cholinergic receptors somewhat increased. Specific antigen attenuated M-cholinergic receptor expression on B-lymphocytes, most pronounced on day 4 after immunization, without affecting the receptor expression in control animals. Possible steric interaction between antigen-binding immunoglobulins and B-lymphocyte M-cholinergic receptors during immune response is suggested.
