Dihexa has been studied as an allosteric potentiator of HGF/c-Met receptor signaling, with preclinical models suggesting effects on dendritic spine density and hippocampal LTP, though significant evidence limitations arose from key retractions in 2025.
An examination of Semax peptide research focusing on HIF-1alpha pathway activation, cerebral ischemia model findings, and the role of melanocortin receptor partial agonism in neuroprotection studies.
A preclinical research review of Noopept’s effects on BDNF and NGF mRNA expression in hippocampal tissue, neuroprotection mechanisms in Alzheimer’s disease models, and the translational limitations of available evidence.
This article examines preclinical research on Selank’s influence on GABAergic gene expression in rodent frontal cortex, including findings from neurotransmission transcriptome studies and proposed allosteric modulation mechanisms distinguishing it from direct benzodiazepine-site agonists.
A preclinical mechanistic overview of how the Semax peptide modulates BDNF-TrkB receptor signaling, downstream MAPK/ERK and PI3K/Akt cascades, and synaptic plasticity across hippocampal and ischemic model systems.
A research-context analysis of Noopept-associated NGF and BDNF mRNA expression patterns in rodent hippocampal models, including NMDA receptor-mediated signaling and Ca2+ transient data.
An analysis of Dihexa’s mechanism as an HGF hinge-region ligand, focusing on c-Met receptor activation, hippocampal dendritic spine density modulation, and synaptogenesis findings from preclinical animal models.
Selank is a synthetic heptapeptide studied for its competitive inhibition of enkephalin-degrading enzymes and BDNF/TrkB signaling modulation in preclinical anxiety research models.
A research-context analysis of P21 peptide’s mechanism of action through LIF pathway partial inhibition, downstream STAT3 disinhibition of hippocampal dentate gyrus neurogenesis, and BDNF-TrkB signaling cross-talk in AD and Down syndrome preclinical models.
A preclinical research overview of Noopept focusing on Alpha-7 nicotinic acetylcholine receptor (alpha7 nAChR) activation in CA1 GABAergic interneuron circ…
