| Popis: | Plasma from healthy subjects inhibited the binding of [ 3 H ]imipramine competitively and [ 3 H ]paroxetine non-competitively to platelet membranes in a volume-dependent manner. Plasma from 40 depressed patients was more effective at inhibiting [ 3 H ]imipramine, but not [ 3 H ]paroxetine, binding compared to plasma from matched controls. This difference was not related to recent antidepressant treatment. The results suggest that the concentration of an endogenous modulator of [ 3 H ]imipramine binding is increased in depressive illness. The concentration of α 1 -acid glycoprotein, a proposed endogenous modulator of [ 3 H ]imipramine binding, did not differ between depressed patients and controls. Our results suggest that factors other than α 1 -acid glycoprotein may modulate [ 3 H ]imipramine binding. |
