ABSTRACT
The beneficial effect of a beta-lactam antibiotic, Ceftriaxone (CEF), to improve depressive-like symptoms has been documented previously, attributed to its modulation of glutamate neurotransmission. Here, we aimed to determine whether CEF could improve LPS-altered glutamatergic signaling associated with neuroinflammation-allied depression. To assess our goals, we established a neuroinflammation-allied depression mice model by injecting lipopolysaccharides (LPS), followed by behavioral and biochemical analysis. LPS-treated mice displayed depressive symptoms, neuroinflammation, dysregulated glutamate and its transporter (GLT-1) expression, altered expression of astrocyte reactive markers (GFAP, cxcl10, steap4, GBP2, and SRGN), and dysregulated BDNF/TrkB signaling. However, these changes were rescued by CEF treatment, as we found decreased neuroinflammation, relief of depression symptoms, and improved GLT-1 and BDNF/TrkB signaling upon CEF treatment. Moreover, GLT-1 and BDNF/TrkB regulation role of CEF was validated by K252a and DHK treatment. In summary, the anti-depressive effects of glutamate modulators, like CEF, are closely related to their anti-inflammatory role.
