Differential effects of vasoactive intestinal peptide, substance P, and somatostatin on immunoglobulin synthesis and proliferations by lymphocytes from Peyer's patches, mesenteric lymph nodes, and spleen.

open access: yesJournal of Immunology, 1986
We examined the effect of vasoactive intestinal peptide, substance P, and somatostatin on concanavalin A (1 microgram/ml)-induced lymphocyte proliferation and immunoglobulin (IgA, IgM, and IgG) synthesis by cells from spleens, Peyer's patches, and ...

The glucagon-like Peptide-2 [PDF]

open access: yes, 2011
Multiple peptide hormones produced within the gastrointestinal system act also in the central nervous system and aid in the regulation of energy homeostasis and metabolism. The list of these peptides is progressively increasing and includes glucagon-like

Reversal of age-related learning deficiency by the vertebrate PACAP and IGF-1 in a novel invertebrate model of aging: the pond snail (Lymnaea Stagnalis) [PDF]

open access: yes, 2014
With the increase of life span, nonpathological age-related memory decline is affecting an increasing number of people. However, there is evidence that age-associated memory impairment only suspends, rather than irreversibly extinguishes, the intrinsic ...

Endothelial Netrin‐4 regulates oligodendrocyte precursor cell proliferation and differentiation via ET‐1 signaling in preterm white matter injury

open access: yesBrain Pathology, EarlyView.
Our findings show early increased Netrin‐4 in mice with PWMI boosts angiogenesis and OPCs proliferation. Later, high levels hinder OPCs differentiation into mature cells, impairing myelination. It may act by stimulating ET‐1 secretion. Abstract Perinatal hypoxia–ischemia is a leading cause of preterm white matter injury (PWMI), yet mechanisms ...

Non-specific activation of human eosinophil functional responses by vasoactive intestinal peptide

open access: yesAllergology International, 2000
Eosinophils and neuropeptides are thought to play effector roles in allergic diseases, such as rhinitis; however, little is known about the biological effects of neuromediators, especially vasoactive intestinal peptide (VIP), on eosinophil functional ...

Triptans and CGRP blockade - impact on the cranial vasculature [PDF]

open access: yes, 2017
The trigeminovascular system plays a key role in the pathophysiology of migraine. The activation of the trigeminovascular system causes release of various neurotransmitters and neuropeptides, including serotonin and calcitonin gene-related peptide ...

Evaluation of the performance of ChatGPT‐4 and ChatGPT‐4o as a learning tool in endodontics

open access: yesInternational Endodontic Journal, EarlyView.
Abstract Aims The aim of this study was to evaluate the accuracy and consistency of responses given by two different versions of Chat Generative Pre‐trained Transformer (ChatGPT), ChatGPT‐4, and ChatGPT‐4o, to multiple‐choice questions prepared from undergraduate endodontic education topics at different times of the day and on different days ...

Neurochemical phenotype and function of endomorphin 2-immunopositive neurons in the myenteric plexus of the rat colon

open access: yesFrontiers in Neuroanatomy, 2014
The distribution and activity of endomorphins (EMs), which are endogenous m-opioid receptor (MOR) ligands in the gastrointestinal tract (GI), have yet to be elucidated. The current study aimed to shed light on this topic. EM2 was expressed in the enteric

Glucagon-Like Peptide-1 Modulates Neurally-Evoked Mucosal Chloride Secretion in Guinea Pig Small Intestine In Vitro. [PDF]

open access: yes, 2011
Glucagon-like peptide-1 (GLP-1) acts at the G protein-coupled receptor, GLP-1R, to stimulate secretion of insulin and to inhibit secretion of glucagon and gastric acid. Involvement in mucosal secretory physiology has received negligible attention. We

The exposomal imprint on rosacea: More than skin deep

open access: yesJournal of the European Academy of Dermatology and Venereology, EarlyView.
Rosacea reflects systemic and environmental interactions, not just a skin disorder. Key factors include environmental triggers, genetic and microbiome influences, diagnostic gaps in skin of colour and social determinants. Advances in multi‐omics and exposome integration highlight pathways towards precision medicine, prevention and equitable, patient ...
