Numerous signaling pathways, such as cyclooxygenase 2 (COX-2), mammalian target of rapamycin (mTOR), mitogen-activated protein kinase (MAPK) signaling, phosphoinositide 3 kinase (PI3K), and the GATA4/p62-mediated autophagy pathways result in the stimulation of NF-B and/or C/EBP pathways, which in turn regulate the SASP secretome (81, 82)

Although the retro-inverso approach may fail to accurately reproduce biological function in the context of helical structures (e.g., p53 or HIV-1 proteins), certain exceptionssuch as the binding of a p53-derived retro-inverso peptide to its regulator MDM2demonstrate that well-designed D-peptides can, in specific cases, effectively mimic the function of the original peptide

Efficient ROS production requires that the copper-binding site forms a chemical environment suitable for both oxidation states of copper
