Nociceptive sensory nerves infiltrate the peripheral trauma area, mediating the biased repair response due to the formation of fibrotic mesenchymal stromal cells (MSCs) neurogenic niche. Nociceptive sensory neuron-derived nerve growth factor activates the TrkA receptors in MSCs and triggers the Hif1α-Twist1 pathway, driving the differentiation of MSCs into myofibroblasts to mediate fibrosis. TPX-0005 exerts therapeutic effects by inhibiting TrkA to reverse fibrosis.
