Axonal regeneration pathway

Axonal regeneration pathways refer to the interconnected and overlapping molecular and cellular signaling systems that regulate the regrowth and repair of axons after injury in the central and peripheral nervous system. These include, but are not limited to, pathways such as JAK/STAT, MAPK (ERK, JNK, p38), PI3K-Akt-mTOR, cAMP/CREB, BMP/SMAD, integrin-mediated signaling, GSK-3β/CLASP, and RhoA/ROCK. Each pathway coordinates distinct and sometimes opposing functions related to cytoskeletal dynamics, gene expression, metabolic support, and response to growth inhibitory or permissive signals. While manipulation of individual pathway components (e.g., promotion of STAT3, mTOR activation, or ROCK inhibition) has led to advances in experimental models for enhancing axonal repair, currently no therapeutic drug targets all "axonal regeneration pathways" collectively. Intervention at this level remains a research strategy rather than a clinically defined target, and drug development focuses on specific molecular nodes within these pathways rather than the broad functional group[2][3][4][6].\n\nThis entry is not a canonical molecule or receptor, but an umbrella term for many interrelated targets and pathways essential to neural repair and regeneration.

Modulation of intracellular signaling cascades after axonal injury, e.g., activation or inhibition of pathways like JAK/STAT, MAPK, mTOR, PI3K-Akt, and RhoA/ROCK to promote neurite outgrowth and reduce inhibitory cues[3][4][6].
