Therefore, the identification of universal biomarkers of ELS-related diseases is very important. The 70-kDa heat shock proteins (HSP70s), specifically HSPA5 and HSPA1B, have been recently shown to be potentially associated with occurrence of anxiety, mood disorders, and schizophrenia; thus, we hypothesized that HSP70s are potential candidate biomarkers of ELS-induced psychopathologies. A maternal separation (MS) procedure in rats was used to model ELS, and the expression of HSPA5 and HSPA1B was investigated in the blood, medial prefrontal cortex (mPFC), and hippocampus of juvenile, preadolescent, and adult animals. We also studied the effects of MS on the long-term potentiation (LTP) and behavioral phenotypes of adult rats. We found that MS enhanced the expression of HSPA1B mRNA in the blood and mPFC of juvenile and preadolescent rats. This increase was accompanied by an increase in the HSPA1A/1B protein levels in the mPFC and hippocampus of juvenile rats that persisted in the mPFC until adulthood. MS juvenile and adult rats showed enhanced HSPA5 mRNA expression in the blood and increased HSPA5 protein expression in the mPFC (juveniles) and hippocampus (adults). Concurrently, MS adult rats exhibited aberrations in LTP in the mPFC and hippocampus and a less anxious behavioral phenotype. These results indicate that MS may produce enduring overexpression of HSPA1B and HSPA5 in the brain and blood. Therefore, both HSP70 family members may be potential candidate peripheral and brain biomarkers of ELS-induced changes in brain functioning.Maternal opioids abuse has some deleterious consequence
