Mounting evidence progressively appreciates the vital interplay between immunity and metabolism in a wide array of immunometabolic chronic disorders, both autoimmune non-autoimmune mediated. The immune system regulates functioning cellular within organs like brain, pancreas and/or adipose tissue by sensing adapting to fluctuations microenvironment’s nutrients, thereby reshaping metabolic pathways that greatly impact pro- or anti-inflammatory immunophenotype. While it is agreed relies on an adequate nutritional status function properly, we are only just starting understand how supply single combined all them termed immunonutrients, can steer cells towards less inflamed, tolerogenic Polyphenols, class secondary metabolites abundant Mediterranean foods, pharmacologically active natural products with outstanding immunomodulatory actions. Upon binding range receptors highly expressed (e.g. AhR, RAR, RLR), they act through mitochondria-centered multi-modal approach. First , polyphenols activate nutrient via stress-response pathways, essential for responses. Second regulate mammalian target rapamycin (mTOR)/AMP-activated protein kinase (AMPK) balance well-tolerated caloric restriction mimetics. Third interfere assembly NLR family pyrin domain containing 3 (NLRP3) endoplasmic reticulum-mitochondria contact sites, inhibiting its activation while improving mitochondrial biogenesis autophagosome-lysosome fusion. Finally chromatin remodeling coordinates epigenetic reprogramming. This work moves beyond well-documented antioxidant properties polyphenols, offering new insights into multifaceted nature these compounds. It proposes mechanistical appraisal regulatory which modulate response, alleviating low-grade inflammation. Furthermore, draws parallels pharmacological interventions polyphenol-based immunonutrition their modes immunomodulation across spectrum socioeconomically impactful diseases such as Multiple Sclerosis, Diabetes (type 1 2) even Alzheimer’s disease.
