Neuropeptides and pain [PDF]

open access: yesAnnals of General Psychiatry, 2010
Neuropeptides comprise a diverse group of chemically distinct molecules, contained in and released from a range of sensory nerves. They are involved in the formation, transmission, modulation and perception of all types of pain (physiological, neuropathic and inflammatory). This fact is reflected on their wide distribution, from primary sensory neurons

Insect Mating Behaviors: A Review of the Regulatory Role of Neuropeptides [PDF]

open access: yesInsects
Insect mating behaviors are complex, diverse, and primarily regulated by neuropeptides and their receptors. Neuropeptides are peptide signaling molecules mainly secreted by insects’ central nervous system (CNS) to reach target organs.

LIT01-196, a Metabolically Stable Apelin-17 Analog, Normalizes Blood Pressure in Hypertensive DOCA-Salt Rats via a NO Synthase-dependent Mechanism

open access: yesFrontiers in Pharmacology, 2021
Apelin is a neuro-vasoactive peptide that plays a major role in the control of cardiovascular functions and water balance, but has an in-vivo half-life in the minute range, limiting its therapeutic use.

Antinociceptive and Cytotoxic Activity of Opioid Peptides with Hydrazone and Hydrazide Moieties at the C-Terminus

open access: yesMolecules, 2020
In the present contribution, we analyze the influence that C-terminal extension of short opioid peptide sequences by organic fragments has on receptor affinity, in vivo analgesic activity, and antimelanoma properties.

Can keratin scaffolds be used for creating three-dimensional cell cultures?

open access: yesOpen Medicine, 2020
Three-dimensional (3D) cell cultures were created with the use of fur keratin associated proteins (F-KAPs) as scaffolds. The procedure of preparation F-KAP involves combinations of chemical activation and enzymatic digestion.

Neuropeptides [PDF]

open access: yesWormBook, 2008
The role of neuropeptides in modulating behavior is slowly being elucidated. With the sequencing of the C. elegans genome, the extent of the neuropeptide genes in C. elegans can be determined. To date, 113 neuropeptide genes encoding over 250 distinct neuropeptides have been identified.

Neuropeptidomics: Mass Spectrometry-Based Identification and Quantitation of Neuropeptides [PDF]

open access: yesGenomics & Informatics, 2016
Neuropeptides produced from prohormones by selective action of endopeptidases are vital signaling molecules, playing a critical role in a variety of physiological processes, such as addiction, depression, pain, and circadian rhythms.
