The present study is designed to investigate the role of glutamate transporter in neuroprotection of ceftriaxone against MPTP induced PD animal model. Young male Wistar rats were subjected to intra-nigral administration of MPTP for the induction of Parkinson's disease. Glutamate modulators like ceftriaxone (CFX), Memantine (MEM) and Dihydrokainate (DHK) were administered to MPTP-lesioned rats. Different behavioral alterations were assessed in between the study period. Animals were sacrificed immediately after behavioral session, and different biochemical parameters were measured. Intranigral administration of MPTP showed significant impairment of motor behavior and marked increase in inflammatory mediators and oxidative stress parameters in rats. In addition, MPTP also produced significant decrease in brain-derived neurotrophic factor (BDNF) in striatum of rats. However, chronic administration of ceftriaxone (200 mg/kg) has shown significant improvement in motor behavioral deficits and oxidative damage. In addition, Ceftriaxone also attenuated the marked increase of NFκB, TNF-α and IL-1β in MPTP treated rats thus, conferring its neuro-inflammatory property. Further, Ceftriaxone significantly restored the decreased activity of BDNF in striatum of MPTP treated rats. Moreover, pre-treatment of memantine (20 mg/kg) with sub-therapeutic dose of ceftriaxone (100 mg/kg) potentiated the protective effect of ceftriaxone. Furthermore, intra-nigral injection of DHK (200 nmol) with lower dose of ceftriaxone (100 mg/kg) reversed the protective effect of ceftriaxone in MPTP treated rats. The present study concluded that ceftriaxone produce beneficial effect against MPTP induced PD like symptoms rats through glutamatergic pathways.
