Objective:
We aimed to indicate the relationship between depression and glutamate, and to
reveal the effect of escitalopram, an antidepressant, which is widely used in depression
treatment and reuptake parameters of glutamate, and to treat depression with
ceftriaxone, one of the beta lactam antibiotics which increased the number and
activity of glutamate transporters.
Methods: In CUMS, rats subjected to series
of different mild stressors in an unpredictable manner for 40 days. On the day 20 rats were
divided in to groups such as CUMS, CUMS+Escitalopram and CUMS+Ceftriaxone. 4 weeks. Treatments were started at 2nd week of CUMS and continued
for 21 days. Anhedonia and antidepressant effect were assessed by sucrose
preference (SP), locomotor activity (LA), elevated plus maze (EPM) and forced
swim test (FST) at the end of the experiment respectively. At the end of the experiment,
behavioral tests were made, and glutamate reuptake time in CA3 (cornuammonis 3)
brain region which are related with depression were measured by means of in
vivo voltammetry technique.
Results: Ceftriaxone
treatment had an antidepressant-like effect. Escitalopram and ceftriaxone increased SP and locomotor
activity, reduced immobility FST, forced swim and time spent in closed arms in
EPM compared to CUMS group. In this in-vivo voltametric study, it was also observed that there was a
significant decrease in glutamate reuptake time in depression.
Conclusion: Escitalopram
and ceftriaxone demonstrated antidepressant-like effects by reversing behavioral changes in CUMS model. Escitalopram
treatment in CA3 region corrected the decrease in glutamate reuptake time which
is consistent with
the hypothesis that enhanced uptake of glutamate might have antidepressant-like
effects.
