course of depression

C urrent data reveals that early adverse life experiences may affect the developmental processes of the brain and can be
involved in the pathogenesis of many psychiatric disorders including depression. It has been highlighted that stress during
pregnancy activates the immune response in the offspring’s central nervous system. Results also show important role fractalkine
(CX3CL1) in the neuron-microglia interactions and consequently in production of pro- and anti-inflammatory factors in the
brain. Therefore, the aim of our study was to examine the impact of prenatal stress as well as the role of fractalkine (CX3CL1) on
the behavioral and biochemical changes in adult rats. Adult 3-months old rats offspring (control and prenatally stressed), after
behavioral verification, received icv injections with exogenous fractalkine. After the treatment, we evaluated time-dependent
effects of fractalkine administration on the behavioral parameters. Moreover, we measured the changes in the production
of pro-inflammatory cytokines in the two structures: Hippocampus and frontal cortex. The obtained data show that 7 days
after treatment with fractalkine the behavioral disturbances evoked by prenatal stress procedure were normalized. Moreover,
prenatal stress activates production of pro-inflammatory cytokines in the hippocampus and frontal cortex. Interestingly,
treatment with fractalkine inhibited the expression of these factors mainly in the frontal cortex. Summing up, our study shows
that the changes in fractalkine may play an important role in the pathogenesis of depression. Importantly, the action of the
chemokine is connected with its effect on production of inflammatory factors in the brain.
