Peptide‐Incorporated Biomaterials Promote Regeneration of Peripheral Nerve Injuries

Advanced Science, EarlyView.
Peptide‐incorporated biomaterials provide precise, tunable biological cues that mimic functional protein domains to regulate behaviors of neurons, Schwann cells, immune cells, and endothelial cells, thereby enhancing axon elongation, Schwann cell support, inflammatory microenvironment modulation, and vascularization, offering a promising alternative to

What doesn't kill you makes you stranger: Dipeptidyl peptidase-4 (CD26) proteolysis differentially modulates the activity of many peptide hormones and cytokines generating novel cryptic bioactive ligands [PDF]

, 2019
Dipeptidyl peptidase 4 (DPP4) is an exopeptidase found either on cell surfaces where it is highly regulated in terms of its expression and surface availability (CD26) or in a free/circulating soluble constitutively available and intrinsically active form.

Optimization and verification of high‐fat diet formulation for establishing a rat model of obesity‐related precocious puberty

Animal Models and Experimental Medicine, EarlyView.
We identified 45% HFD as the optimal formulation to establish a juvenile rat model of obesity‐related precocious puberty. It elicits robust phenotypic (early vaginal opening, obesity), histological (advanced ovarian development), and endocrine (elevated HPG axis hormones) alterations, with leptin‐mediated GnRH secretion as a core mechanistic driver ...

Neuropeptide Y receptors: How to get subtype selectivity

Frontiers in Endocrinology, 2013
The neuropeptide Y system is a multireceptor/multiligand system consisting of four receptors in humans (hY1, hY2, hY4, hY5) and three agonists (NPY, PYY, PP) that activate these receptors with different potency.

Neuropeptide receptors as potential antiepileptic drug targets : focus on the ghrelin axis [PDF]

, 2014
Epilepsy is a very serious neurological disorder which is often underrepresented. Around 50 million individuals worldwide have active epilepsy with recurrent seizures and in spite of the medical advances over the years, 30% of these patients remain as ...

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

Animal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Large-scale deorphanization of Nematostella vectensis neuropeptide G protein-coupled receptors supports the independent expansion of bilaterian and cnidarian peptidergic systems

eLife
Neuropeptides are ancient signaling molecules in animals but only few peptide receptors are known outside bilaterians. Cnidarians possess a large number of G protein-coupled receptors (GPCRs) – the most common receptors of bilaterian neuropeptides – but ...

Hypnotic doses of fazamorexant induced less impairment on balance and cognition than zolpidem in healthy younger and elderly individualse

British Journal of Clinical Pharmacology, EarlyView.
Aims Fazamorexant is a dual orexin receptor antagonist being developed for the treatment of insomnia. This study aims to determine the dose‐exposure‐response relationship of single‐dose fazamorexant vs. zolpidem in young adult and elderly healthy Chinese volunteers. Methods This single‐centre, randomized, double‐blind, double‐dummy, placebo‐ and active‐

Recent advances in vasoactive intestinal peptide physiology and pathophysiology: focus on the gastrointestinal system. [PDF]

, 2019
Vasoactive intestinal peptide (VIP), a gut peptide hormone originally reported as a vasodilator in 1970, has multiple physiological and pathological effects on development, growth, and the control of neuronal, epithelial, and endocrine cell functions ...
