Optogenetic stimulation of infralimbic PFC reproduces ketamine’s rapid and sustained antidepressant actions

Abstract: Ketamine produces rapid and sustained antidepressant actions in depressed patients, but the precise cellular mechanisms underlying these effects have not been identified. Here we determined if modulation of neuronal activity in the infralimbic prefrontal cortex (IL-PFC) underlies the antidepressant and anxiolytic actions of ketamine. We found that neuronal inactivation of the IL-PFC completely blocked the antidepressant and anxiolytic effects of systemic ketamine in rodent models and that ketamine microinfusio… Show more

“…Immunoblot analysis shows that GLYX-13 also increases c-Fos immunoreactivity in the PFC (Supplemental Figure 2a). Immunohistochemistry demonstrates that GLYX-13 increases c-Fos labeling in the infralimbic mPFC (Supplemental Figure 2b), with no significant effects in prelimbic mPFC, similar to the effects of ketamine (Fuchikami et al, 2015).…”

“…The behavioral effects of both ketamine and GLYX-13 are blocked by pretreatment with an AMPA receptor antagonist, indicating a requirement for glutamate-AMPA activity (Burgdorf et al, 2013;Maeng et al, 2008;Li et al, 2010). Ketamine rapidly increases c-Fos, a marker of neuronal activity, in the mPFC, consistent with stimulation of glutamate-AMPA signaling (Fuchikami et al, 2015). Immunoblot analysis shows that GLYX-13 also increases c-Fos immunoreactivity in the PFC (Supplemental Figure 2a).…”

“…HBOT is believed to have anti-inflammatory effects, reducing the excess of proinflammatory cytokine activation such as TNF-alpha and facilitating improvement by provocation of stem cell activity [7][8][9][10]. The combination therapy of infused ketamine administered concurrent to TMS appears to address the abnormalities in brain circuits found both in treatment resistant depression and treatment resistant central pain [11][12][13][14][15][16]. Additionally, ketamine is known to act as a TNF-alpha inhibitor, thus favoring an anti-inflammatory effect [17].…”

“…A cetamina também apresenta, como dito anteriormente, potente ação terapêutica na depressão maior e alguns transtornos de ansiedade. Segundo Fuchikami (Fuchikami et al, 2015), estes efeitos são possivelmente modulados no IL. De interesse para o nosso estudo são as ligações entre o IL e o NAcSh já que esta conexão está vinculada ao controle do comportamento motivado por pistas contextuais (Rocha & Kalivas, 2010).…”
