| Hydrogen sulfide (H₂S), a gaseous signaling molecule, has been implicated in Alzheimer’s disease (AD) pathology with both neuroprotective and neurotoxic roles, depending on concentration, source, and context. - It was found that the endogenous H2S level in the brain of AD patients was significantly lower than that of normal people. -A cysteine-rich diet or supplementation with an appropriate amount of N-acetylcysteine is beneficial to the synthesis of H2S in the brain -Activates Nrf2, upregulates antioxidant genes Reduces oxidative stress, neuroprotective. -Inhibits NF-κB activation Suppresses inflammatory cytokines like TNF-α, IL-1β -Reduces Aβ aggregation and toxicity -Enhances cerebral blood flow |

| NLRP3 (NOD-like receptor pyrin domain-containing protein 3) is a protein that plays a crucial role in the regulation of inflammation and immune responses. NLRP3 typically has high expression in cancers, with poor prognosis. For alzheimer's disease: -NLRP3 is upregulated in Alzheimer's disease (AD) -NLRP3 is activated in microglia in response to amyloid-β (Aβ) and tau aggregates. -Promotes tau hyperphosphorylation and spread via inflammation-driven pathways. |
