The content of spermidine and spermine polyamines in the rat brain under hyperoxic convulsions and four hours after convulsions decreases sharply. The intraperitoneal administration of polyamines before hyperbaric oxygenation decreased the rate of development of hyperoxic convulsions in rats. In the
Neuropeptide Y (NPY) is an important 36 amino acid peptide that is abundantly expressed in the mammalian CNS and is known to be an endogenous modulator of seizure activity, including in rat models of Genetic Generalised Epilepsy (GGE) with absence seizures. Studies have shown that viral-mediated
Ghrelin, a 28-amino-acid peptide, is mainly secreted by the stomach. Evidence has shown ghrelin to have neuroprotective effects. However, whether ghrelin protects hippocampal neurons against cell death in pilocarpine-induced seizures is unknown. We used Nissl staining to show that ghrelin attenuated
Neuropeptide Y (NPY) is a 36-amino-acid peptide that attenuates seizure activity following direct infusion or adeno-associated virus (AAV)-mediated expression in the central nervous system. However, NPY activates all NPY receptor subtypes, potentially causing unwanted side effects. NPY13-36 is a
Secretoneurin is a 33-amino acid peptide, generated in brain by proteolytic processing of secretogranin II. The distribution of secretoneurin-like immunoreactivity and secretogranin II mRNA was investigated in the hippocampus of the rat. Secretogranin II mRNA was found in high concentrations
Peptides DBI 42-50 (DRPGLLDLK) and DBI 43-50 (RPGLLDLK) are synthetic fragments of an 18 amino acid peptide called octadecaneuropeptide (QATVGDVNTDRPGLLDLK), a brain derivative of diazepam-binding inhibitor (DBI). The two peptides were unilaterally injected into the dorsal hippocampus (granule cells
Neuropeptide Y (NPY) is a 36-amino-acid peptide that exhibits a large number of physiological activities in the central and peripheral nervous systems. NPY mediates its effects through the activation of six G-protein-coupled receptor subtypes named Y(1), Y(2), Y(3), Y(4), Y(5), and y(6). Evidence
Neuropeptide Y (NPY), a 36-amino acid peptide, is present in some hippocampal interneurons and nerve terminals and seems to modulate glutamatergic transmission in this structure. Earlier studies of some other authors showed an increase in NPY expression in the hippocampus during seizures and
Etelcalcetide is a novel d-amino acid peptide that functions as an allosteric activator of the calcium-sensing receptor and is being developed as an intravenous calcimimetic for the treatment of secondary hyperparathyroidism in patients with chronic kidney disease on hemodialysis. To support
Large conductance calcium-activated (BK) channels are broadly expressed in neurons and muscle where they modulate cellular activity. Decades of research support an interest in pharmaceutical applications for modulating BK channel function. Here we report a novel BK channel-targeted peptide with
Fragile X syndrome (FXS) is the most common form of inherited intellectual disability and the leading known genetic cause of autism. Fragile X mental retardation protein (FMRP), which is absent or expressed at substantially reduced levels in FXS, binds to and controls the postsynaptic translation of
