AEVs containing miR-146a-5p are taken up by microglia and suppress IRAK1/TRAF6, disrupting sustained NF-κB activation that maintains pathological memory. miR-146a also targets NOTCH1 and HDAC1, restoring repressive histone marks at previously trained enhancer regions. The mechanism has strong conceptual support from peripheral trained immunity studies but faces significant in vivo delivery challenges.
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
