Plasma profile of pro-inflammatory cytokines and chemokines in cocaine users under outpatient treatment: influence of cocaine symptom severity and psychiatric co-morbidity
The treatment for cocaine use constitutes a clinical challenge because of the lack of appropriate therapies and the high rate of relapse. Recent evidence indicates that the immune system might be involved in the pathogenesis of cocaine addiction and its co-morbid psychiatric disorders. This work examined the plasma pro-inflammatory cytokine and chemokine profile in abstinent cocaine users (n = 82) who sought outpatient cocaine treatment and age/sex/body mass-matched controls (n = 65). Participants were assessed with the diagnostic interview Psychiatric Research Interview for Substance and Mental Diseases according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition,…
Cocaine-induced changes in CX3CL1 and inflammatory signaling pathways in the hippocampus: Association with IL1β
Cocaine induces neuroinflammatory response and interleukin-1 beta (IL1β) is suggested a final effector for many cocaine-induced inflammatory signals. Recently, the chemokine fractalkine (CX3CL1) has been reported to regulate hippocampus-dependent neuroinflammation and synaptic plasticity via CX3C-receptor 1 (CX3CR1), but little is known about the impact of cocaine. This study is mainly focused on the characterization of CX3CL1, IL1β and relevant inflammatory signal transduction pathways in the hippocampus in acute and repeated cocaine-treated male mice. Complementarily, the rewarding properties of cocaine were also assessed in Cx3cr1-knockout (KO) mice using a conditioned place preference (…
