2013, Advances in PharmacologyCitation Excerpt :Given the preliminary findings that repeated social stress produces a decrease in LC discharge rate that is apparent 2 days after the last stress, we expect that this is due to the engagement of ENK afferents to the LC, and so, ppENK is predicted to be upregulated in LC afferents of social stressed rats at this time. This would be consistent with studies showing heightened analgesia following social defeat (Miczek, 1991; Rodgers & Randall, 1985) which is thought to reflect an increase in endogenous opioid release in brain regions associated with pain processes (Kulling, Frischknecht, Pasi, Waser, & Siegfried, 1988). Interestingly, ENK is colocalized with Glu in LC afferents (Barr & Van Bockstaele, 2005; Van Bockstaele, Saunders, et al., 2000), and glutamatergic afferents have been implicated in the LC withdrawal response (Akaoka & Aston-Jones, 1991; Rasmussen & Aghajanian, 1989; Rasmussen, Beitner-Johnson, Krystal, Aghajanian, & Nestler, 1990).
