HDACs Immunoreactivities in Monoaminergic and Neuropeptidergic Neurons.

The percentage of immunoreactive cells was assessed at the confocal laser scanning microscopy. Values are means ± S.E.M. Nuclear or cytoplasmic localization of HDACs was determined based on the colocalization with Hoechst 33342. The extent of HDACs immunoreactivities was determined on the intensity and area of the immunoreactivities: “+++”, strong immunoreactivity; “++”, moderate immunoreactivity; “+”, weak immunoreactivity; “−“, no immunoreactivity above background.
