Special Issue Information
Dear Colleagues,
Converging clinical and preclinical evidence documents that oxidative stress plays a critical role in the etiopathogenesis of psychiatric and neurological disorders. Mitochondria are a major source and target of reactive oxygen species (ROS) triggered by intense bioenergetic processes within cells, including neurons and glia.
Imbalances in neuronal redox status towards the excessive production of ROS as side products lead to the hyperactivation of astrocytes and microglia, resulting in the enhancement of ROS generation and the overactivation of inflammatory pathways. In numerous clinical studies, markers of oxidative stress are elevated in patients with neuropsychiatric disorders, and antioxidant treatment has provided promising results in the management of both psychiatric and neurological symptoms, either as monotherapy or adjunctive therapy. For example, through its antioxidant effects, the reduction of cytokine activity, the modulation of dopamine and glutamate transmission, and the reversal of mitochondrial dysfunction, the acetylated precursor of L-cysteine (N-acetyl-L-cysteine) has shown therapeutic properties for the treatment of multiple psychiatric disorders, including schizophrenia, anxiety, and substance-use disorders (SUDs). Similarly, thanks to its marked anti-inflammatory and antioxidant properties, the broad-spectrum antibiotic minocycline has been proposed as an adjuvant treatment for neurodegenerative and psychiatric diseases featuring an inflammatory basis. On the other hand, aberrant inflammatory markers have been linked to poor response to antidepressant medications, and numerous clinical trials have documented a positive correlation between antipsychotic efficacy and restoration of the imbalance of pro- and anti-inflammatory cytokine levels in patients with schizophrenia.
The aim of this Special Issue is to collect research and/or review articles that may help to understand the complex interplay among oxidative stress, mitochondrial dysfunction, and neuroinflammation in the pathophysiology of neuropsychiatric disorders, with the final goal of introducing novel therapeutic intervention strategies. We especially welcome the submission of articles focusing on the role of genetic and non-genetic risk factors (environmental pollutants, bad lifestyle habits, food contaminants, obesity) on the pathological crosstalk between ROS and inflammation in the CNS.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pharmaceuticals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs).
