[Study of physiological functions of human ceruloplasmin. The effect of ceruloplasmin on immunocytes in a normal state and in pathology].

The immunomodulating effect of ceruloplasmin (CP) on the major components of the immunocompetent system of the organism--the natural resistance system and the specific immune response--has been established. CP can exert various influences on the level of expression of specific markers of T- and B-lymphocytes (as determined by various modifications of the rosette-forming test), on the phagocytic activity of neutrophils and monocytes as well as on the activity of "respiratory burst" enzymes. CP modulation was found to depend predominantly on the initial level of the immunological parameters to be determined, i.

Modulatory effects of ceruloplasmin on lymphocytes, neutrophils and monocytes of patients with altered immune status.

We investigated the effect of plasma ceruloplasmin (Cp) on the different types of lymphocyte rosetting, and phagocytosis of polystyrene particles and culture Candida albicans by peripheral blood neutrophils and monocytes. Lymphocytes, neutrophils, and monocytes were isolated from the blood of patients with elevated immuno-status (n = 9), healthy donors (n = 21), and patients with reduced immuno-status (n = 21). The ability of Cp to decrease the number of lymphocytes forming E- and EAC-rosettes and rosettes with auto-erythrocytes was shown for both patients and healthy donors.
