Based upon experimental studies with multiple in vitro models (i.e., PC 12 cells, NSC-34 hybrid cells, SH-SY5Y cells, the immune cell line U-937) and several rodent in vivo models, six atypical antipsychotic drugs, within direct experimental comparisons and/or preconditioning protocol studies with six different stressor/toxic agents (i.e. rotenone, hydrogen peroxide, MPP+, serum withdrawal, beta-amyloid, and corticosterone) were demonstrated to induce neuroprotective effects with consistently hormetic dose response patterns. These findings suggest that some of the reported neuroprotective effects of atypical human antipsychotic agents are likely to be mediated by hormetic mechanisms. These findings may have important implications for both experimental study design and clinical therapeutics.Nicotine exposure increases the release of glutamate in part through stimulatory effects on pre-synaptic nicotinic acetylcholine receptors (nAChRs). To assess the impact of chronic electronic (e)-cigarette use on these drug dependence pathways, we exposed C57BL/6 mice to three types of inhalant exposures for 3 months; 1) e-cigarette aerosol generated from liquids containing nicotine (ECN), 2) e-cigarette aerosol generated from liquids containing vehicle chemicals without nicotine (Veh), and 3) air only (AC). We investigated the effects of daily e-cigarette exposure on protein levels of α7 nAChR and α4/β2 nAChR, gene expression and protein levels of astroglial glutamate transporters, including glutamate transporter-1 (GLT-1) and cystine/glutamate antiporter (xCT), in the frontal cortex (FC), striatum (STR) and hippocampus (HIP). We found that chronic inhalation of ECN increased α4/β2 nAChR in a
