Stress-induced amino acid-sensitive pathway, GCN2 signaling is activated in CTI conditions at the very early stages, thus inducing Treg functions not necessary at that stage of wound healing, thus inhibiting/disrupting the natural course of the acute pro-inflammatory phase. Increased expression of Tregs at early stages delays wound healing through the GCN2 pathway.
