17 beta Estradiol-induced increase in brain dopamine D-2 receptor: antagonism by MIF-1.

abstract：:The presence of atrial natriuretic peptide (ANP) binding sites in the thymic cortex, medulla, and splenic white pulp suggests that this peptide may have immunoregulatory activity. We examined the effect of ANP on human natural killer (NK) cell activity. ANP significantly augmented NK cell cytotoxicity after twenty-fou...
