This hypothesis proposes that SPP1-mediated microglial activation creates discrete temporal windows during which NLRP3 inflammasome hyperactivation becomes the dominant driver of neurodegeneration. During these critical periods, SPP1 signaling through CD44 and integrin receptors not only recruits microglia but also primes them for enhanced NLRP3 activation by upregulating inflammasome components and creating mitochondrial stress. The approach involves deploying inducible NLRP3 inhibitors (such a
**Background and Rationale**
The NLRP3 inflammasome has emerged as a critical upstream regulator of neuroinflammation in age-related neurodegenerative diseases, particularly Alzheimer's disease and related tauopathies. This multiprotein complex, consisting of NLRP3 (NOD-like receptor family pyrin domain containing 3), ASC (apoptosis-associated speck-like protein containing a CARD), and caspase-1, serves as a cellular sensor for damage-associated molecular patterns (DAMPs) and pathogen-associate
