[Abstract] The cyclic GMP⁃AMP synthase⁃stimulator of interferon genes(cGAS⁃STING)signaling pathway is a pivotal innate
immune mechanism for sensing cytosolic double ⁃ stranded DNA. Its canonical role is to exert antiviral immunity by inducing the
expression of typeⅠinterferons and pro⁃inflammatory cytokines. However,recent studies have revealed that key components of this
pathway possess non⁃canonical functions capable of inducing autophagy through diverse mechanisms. Recent studies have revealed
that STING can also drive lysosomal biogenesis mediated by transcription factor EB(TFEB). These findings suggest that the cGAS⁃
STING axis serves as a critical bridge linking innate immunity with the autophagy⁃lysosomal system. The activation of this pathway
yields pleiotropic effects,ranging from homeostatic preservation to the aggravation of disease progression,depending on the specific
pathological milieu. This review aims to summarize the latest advances in the molecular mechanisms and pathophysiological roles of
the cGAS⁃STING⁃mediated activation of the autophagy⁃lysosomal system,providing a comprehensive framework for understanding its
biological functions and informing potential therapeutic strategies for related diseases.
