- Females have higher rates of depression as compared to males, with mood disorder symptoms often occurring during periods of ovarian hormone fluctuations. The NMDA receptor antagonist, Ketamine (KET), has shown promise as a rapid-acting antidepressant, exerting effects within hours of treatment. There is a growing wealth of data regarding the neural mechanisms that mediate this rapid antidepressant effect (e.g., BDNF and mTOR), yet sex differences in these molecular mechanisms remain to be resolved. My research aims to: 1) determine if C57BL/6 mice display sex differences in KET sensitivity, 2) determine the role of endogenous ovarian hormones and their respective receptors to promote KET sensitivity, & 3) examine whether the same molecular mechanisms mediating ketamine antidepressant effects described in male rodents also applies to females.
