RESUMO

Immunocytochemical expression of Connexin 43 (Cx 43) in the rat Supraoptic Nucleus was analyzed following dehydration, using sequence-specific anti-Cx 43 antibodies (designated 13-8300, 71-0700, and sc-9059) that exhibit differential recognition of Cx 43. Punctate and longitudinally arranged immunostaining patterns of Cx 43 labeling, as evidenced by antibody sc-9059, was detected overlaying the nucleus of magnocellular neuroendocrine cells. This novel form of longitudinally arranged Cx 43 immunoreactivity was modified by dehydration and halothane exposure, but not lactation.
