Recently, the hallmarks of aging were updated to include dysbiosis, disabled macroautophagy, and chronic inflammation. In particular, low-grade inflammation during aging, without overt infection, is defined as "inflammaging," which associated with increased morbidity mortality in population. Emerging evidence suggests a bidirectional cyclical relationship between development age-related conditions, such cardiovascular diseases, neurodegeneration, cancer, frailty. How crosstalk other underlies biological mechanisms disease thus particular interest current geroscience research.

The increasing life expectancy has led to a higher incidence of age-related neurodegenerative conditions. Within this framework, neuroinflammation emerges as significant contributing factor. It involves the activation microglia and astrocytes, leading release pro-inflammatory cytokines chemokines infiltration peripheral leukocytes into central nervous system (CNS). These instances result in neuronal damage neurodegeneration through activated nucleotide-binding domain leucine-rich repeat containing (NLR) family pyrin protein 3 (NLRP3) nuclear factor kappa B (NF-kB) pathways decreased erythroid 2-related 2 (Nrf2) activity. Due limited effectiveness regarding inhibition neuroinflammatory targets using conventional drugs, there is challenging growth search for innovative therapies alleviating CNS diseases or even before their onset. Our results indicate that interventions focusing on Interleukin-Driven Immunomodulation, Chemokine (CXC) Receptor Signaling Expression, Cold Exposure, Fibrin-Targeted strategies significantly promise mitigate processes. approaches demonstrate potential anti-neuroinflammatory effects, addressing conditions such Multiple Sclerosis, Experimental autoimmune encephalomyelitis, Parkinson’s Disease, Alzheimer’s Disease. While findings are promising, immunomodulatory often face limitations due Immune-Related Adverse Events. Therefore, conduction randomized clinical trials matter mandatory, will pave way promising future development new medicines with specific therapeutic targets.

This category progressive diseases includes, but is not limited to, Alzheimer's disease, Parkinson's and prion diseases. Shared pathogenesis involves accumulation misfolded proteins, chronic neuroinflammation, synaptic dysfunction, ultimately leading to irreversible neuronal loss, measurable cognitive deficits, death. Presently, there are few no effective treatments halt advancement We hypothesized that directly targeting neuroinflammation by downregulating transcription factor, NF-κB, inflammasome protein, NLRP3, would be neuroprotective.
