Mechanistically, nitric oxide synthase (NOS) converts arginine, NADPH, and oxygen into nitric oxide, which inhibits apoptosis by altering cellular redox states (50, 51)

To better understand biofilm development and persistence in chronic wounds, Figure 2 illustrates the stages of the biofilm life cycle, including adhesion, microcolony formation, maturation, and dispersion, as well as host immune responses such as neutrophil recruitment, M1/M2 macrophage polarization, and cytokine signaling (e.g., interleukin-1 beta [IL-1], tumor necrosis factor-alpha [TNF-], interleukin-6 [IL-6], interleukin-8 [IL-8], interleukin-12 [IL-12]), which collectively contribute to immune evasion and chronic infection 40 - 43

BPC-157 contributes a signaling-focused component commonly studied in models involving cellular communication and vascular-associated response behavior, while TB-500 is investigated for actin-associated signaling, cellular migration, and structural organization
