Foxo4-DRI vs HLDF-6

D-retro-inverso peptide that disrupts Foxo4/p53 interaction in senescent cells; restores p53-mediated apoptosis selectively in senescent cells; clears cellular "zombie cells"

A breakthrough senolytic peptide that selectively eliminates senescent cells by restoring their ability to undergo apoptosis. Produced dramatic rejuvenation effects in preclinical studies.

Modulates cholinergic neurotransmission. Reduces amyloid-β toxicity and protects against oxidative stress-induced neuronal damage. May enhance memory consolidation via acetylcholine pathway upregulation.

A hexapeptide fragment of Human Leukemia Differentiation Factor with neuroprotective and memory-enhancing properties identified primarily in Russian academic research. Studied for cognitive decline associated with aging and Alzheimer's-like pathology.
