Mitochondrial NAD+ Pools, Complex I Function, and Peptide Research Targeting the NAMPT/NMNAT Axis
Mitochondrial NAD+ pools are regulated by NMNAT3, distinct from cytoplasmic pools. Complex I requires NAD+ as hydride acceptor; its aging dysfunction links to NAMPT decline and PARP-1/CD38 substrate competition.

Peptides in Cognitive Research: BDNF/TrkB Signaling, Neuroplasticity Markers, and Preclinical Nootropic Data
Review of how peptides including Selank, Semax, BPC-157, and GHK-Cu modulate BDNF/TrkB signaling, induce neuroplasticity markers (Arc, synapsin-1, GluA1), and perform in preclinical memory models including MWM, NOR, and passive avoidance.

Peptides in UV Photodamage Research: MC1R-Mediated Melanogenesis, Nrf2/ARE Induction, and DNA Repair Enzyme Activation
UV photodamage research models examine how peptide ligands of MC1R activate cAMP/PKA/MITF melanogenesis signaling, how Nrf2/ARE pathway induction limits oxidative DNA lesions, and how CPD photolyase-equivalent DNA repair mechanisms are activated — with GHK-Cu and PT-141 serving as molecular tools in defined cellular systems.
