Dose-dependent impact of pretreatment (imprinting) with histamine and serotonin on the phagocytic activity of Tetrahymena.

Zsuzsanna Darvas, G. Csaba

Abstract

Serotonin and histamine stimulate the phagocytic activity of Tetrahymena at primary interaction. The effect of histamine is dose-dependent. While serotonin elicits an imprinting-like phenomenon at a high concentration, histamine induces no imprinting, probably for 1 volutionary reasons.
