Vinpocetine attenuates 5-fluorouracil-induced intestinal injury: role of the Keap1/Nrf2/HO-1, NF-κB/TLR4/SOCS3 and RIPK1/RIPK3/MLKL signals.
Objectives: 5-Fluorouracil (5-FU) is a chemotherapy drug commonly prescribed in cancer management. Unfortunately, intestinal mucositis restricts 5-FU clinical use. Vinpocetine (VNP) is a synthetic alkaloid that is derived from vincamine. Our study was conducted to elucidate the intestinal protective effects of VNP on 5-FU intestinal injury in rats and explore the underlying mechanisms.
Materials and methods: 5-FU was injected i.p. for five days, while VNP was given P.O (5 and 10 mg/kg).
Results: VNP effectively mitigates oxidative stress by a significant increase in GSH and SOD and decreasing MDA content mediated by Nrf2, HO-1 upregulation, and significant Keap1 downregulation. VNP mitigated inflammatory perturbations by decreasing MPO, TNF-α, IL-1β, and IL-6 facilitated by downregulating NF-κB and TLR4 and upregulating SOCS3 levels. In addition, the RIPK1, RIPK3, MLKL, and caspase-8 expression levels were significantly decreased, evidenced improvement of intestinal necroptosis by VNP.
Conclusion: Hence, VNP potently prevents intestinal injury induced by 5-FU by modulating Keap1/Nrf2/HO-1, NF-κB/TLR4/SOCS3, and RIPK1/RIPK3/MLKL signals.
期刊介绍：
The journal Immunopharmacology and Immunotoxicology is devoted to pre-clinical and clinical drug discovery and development targeting the immune system. Research related to the immunoregulatory effects of various compounds, including small-molecule drugs and biologics, on immunocompetent cells and immune responses, as well as the immunotoxicity exerted by xenobiotics and drugs. Only research that describe the mechanisms of specific compounds (not extracts) is of interest to the journal.
The journal will prioritise preclinical and clinical studies on immunotherapy of disorders such as chronic inflammation, allergy, autoimmunity, cancer etc. The effects of small-drugs, vaccines and biologics against central immunological targets as well as cell-based therapy, including dendritic cell therapy, T cell adoptive transfer and stem cell therapy, are topics of particular interest. Publications pointing towards potential new drug targets within the immune system or novel technology for immunopharmacological drug development are also welcome.
With an immunoscience focus on drug development, immunotherapy and toxicology, the journal will cover areas such as infection, allergy, inflammation, tumor immunology, degenerative disorders, immunodeficiencies, neurology, atherosclerosis and more.
Immunopharmacology and Immunotoxicology will accept original manuscripts, brief communications, commentaries, mini-reviews, reviews, clinical trials and clinical cases, on the condition that the results reported are based on original, clinical, or basic research that has not been published elsewhere in any journal in any language (except in abstract form relating to paper communicated to scientific meetings and symposiums).
