An IL-6 receptor antagonist attenuates postpartum anhedonia, but has no effect on anhedonia precipitated by subchronic stress in female rats.

abstract：:Haloperidol has recently been found to be metabolized to its pyridinium ion (HP+). This conversion of haloperidol to HP+ appears to be similar to the activation of the dopaminergic neurotoxin N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) to N-methyl-4-phenyl pyridinium ion (MPP+). MPP+ is responsible for the dam...
