Special Issue Information

Dear Colleagues,

Attenuation of the chronic inflammation caused by the dysregulated NF-κB signaling pathway under pathological conditions has been shown to be beneficial for the treatment of many common human diseases such as metabolic diseases associated with overnutrition, autoimmune diseases, and cancer. In cells, activation of NF-kappaB transcription factors requires the sequential activation of many signaling components including those from cell membrane receptors such as TNFRs, TLRs, IL1R, etc., receptor adaptor proteins, the ubiquitination–proteasome system, IkappaB kinase, and other protein kinases and regulatory proteins. In the past two decades, the growing interest in targeting different signaling components to mitigate over-activated NF-κB activities under disease conditions has resulted in the identification of many inhibitors for disease treatment. In this special Issue, we invite authors in this field to report their original research discoveries or review articles pertaining to novel therapeutic approaches for targeting the signaling proteins in the NF-kappaB pathway. We are especially interested in approaches that place consideration on avoiding the side effects of overly inhibiting the inflammatory response due to induced apoptosis and IL-1β secretion.

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). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Background: Accumulating evidence suggests that nuclear factor (NF)-κB is involved in the pathophysiology of mood disorders. Objectives and Methods: We conducted two experimental protocols in rats to investigate the effects of a selective NF-κB inhibitor (JSH-23) on (i) lipopolysaccharide (LPS)-induced inflammation and (ii) [...] Read more.
Background: Accumulating evidence suggests that nuclear factor (NF)-κB is involved in the pathophysiology of mood disorders. Objectives and Methods: We conducted two experimental protocols in rats to investigate the effects of a selective NF-κB inhibitor (JSH-23) on (i) lipopolysaccharide (LPS)-induced inflammation and (ii) on behavioral phenotypes in rat models of depression (sucrose consumption test and forced swim test) and mania (amphetamine-induced hyperactivity test). Additionally, we tested the effects of JSH-23 on levels of inflammatory components (interleukin-6, prostaglandin E2, nuclear phospho-p65, and tumor necrosis factor-α) in the brain. Results: Acute treatment with JSH-23 (10 mg/kg, intraperitoneally [ip]) led to potent anti-inflammatory effects in LPS-treated rats, including a diminished hypothermic response to LPS and a reduction in pro-inflammatory mediators’ levels in the brain. Chronic treatment with JSH-23 (3 mg/kg, ip, once daily, for 14 days) resulted in robust antidepressant-like effects (increased sucrose consumption and decreased immobility time). The antidepressant-like effects of JSH-23 were mostly accompanied by a reduction in levels of pro-inflammatory mediators in the brain. On the other hand, JSH-23 did not reduce amphetamine-induced hyperactivity. Conclusions: Altogether, these data suggest that NF-κB may be a potential therapeutic target for pharmacological interventions for depression. Full article
