"Naringenin: A Promising Immunomodulator for Anti-Inflammatory, Neuroprotective, and Anti-Cancer Applications".

Abstract

Background: Inflammatory, immune, and neurodegenerative diseases constitute a category of persistent and debilitating conditions affecting millions worldwide, with inter-twined pathophysiological pathways. Recent research has spotlighted naturally occurring compounds like naringenin for potential therapeutic applications across multiple ailments.

Objective: This review offers an encompassing exploration of naringenin's anti-inflamma-tory, immune-protective, and neuroprotective mechanisms, elucidating its pharmacological targets, signal transduction pathways, safety profile, and insights from clinical investigations.

Methods: Data for this review were amassed through the scrutiny of various published studies via search engines such as PubMed and Google Scholar. Content from reputable publishers including Bentham Science, Taylor and Francis, Nature, PLOS ONE, among others, was referenced.

Results: Naringenin exhibits substantial anti-inflammatory effects by restraining the NF-κB signaling pathway. It activates Nrf2, renowned for its anti-inflammatory properties, inducing the release of hemeoxynase-1 by macrophages. Furthermore, naringenin treatment downregulates the expression of Th1 cytokines and inflammatory mediators. It also impedes xanthine oxidase, counteracts reactive oxygen species (ROS), scavenges superoxide radicals, mitigates the accessibility of oxygen-induced K+ erythrocytes, and reduces lipid peroxidation. Naringenin's antioxidant prowess holds promise for addressing neurological conditions.

Conclusion: Extensive research has been undertaken to establish the anti-inflammatory, immunomodulatory, and neuroprotective attributes of naringenin across various medical domains, lending credence to its pharmacological utility. The principal obstacle to naringenin's adoption as a therapeutic agent remains the dearth of in vivo data. Efforts should focus on rendering naringenin delivery patient-friendly, economically viable, and technologically advanced.
