The effects of Li+ upon hematopoiesis have been proposed to be due to two different systems modification of the activity of the membrane Na+/K+-ATPase, and the inhibition of adenylate cyclase. Monovalent cation flux, in particular Na+ transport, is known to influence the differentiation and proliferation of hematopoietic stem cells. For instance, ouabain, an effective inhibitor of the membrane Na+/K+-ATPase, blocks the proliferation of lymphocytes and has been shown to attenuate the Li+-induced proliferation of granulocyte precursors [208]. Conversely, Li+ can reverse the actions of amphotericin and monensin, which mediate Na+ transport and which inhibit CFU-GM, CFU-E, and CFU-MK colony formation in the absence of Li+ [209]. Therefore, the influence of Li+ upon normal physiological cation transport—for example, its influence upon Na+/K+-ATPase activity—may be partly responsible for the observed interference in hematopoiesis.
