**Molecular Mechanism and Rationale**
The SPP1 (secreted phosphoprotein 1, osteopontin)-HIF1α metabolic rewiring pathway represents a sophisticated cellular reprogramming mechanism that fundamentally alters microglial bioenergetics during neuroinflammation. This pathway begins when SPP1, a matricellular protein highly upregulated in activated microglia and infiltrating macrophages, binds to αvβ3 and CD44 integrin receptors on microglial cell surfaces. Upon SPP1 binding, these receptors initiate
The cGAS-STING pathway drives neuroinflammation in ALS through aberrant cytoplasmic mitochondrial DNA recognition, but therapeutic intervention may be more effectively achieved by targeting the downstream kinase TBK1 rather than STING itself. Following STING activation by cGAMP, the pathway's inflammatory output critically depends on TBK1 (TANK-binding kinase 1), a 729-amino acid serine/threonine kinase that serves as the obligate signal transducer for both type I interferon and pro-inflammatory
