A 3D Human Bone and Bone Marrow‐on‐a‐Chip Model for In Vitro Bone Remodeling and Immune Cell Maintenance

Advanced Science, EarlyView.
This study presents a human Bone (and Bone Marrow)‐on‐a‐Chip model based on native human bone scaffolds and autologous cells. Dynamic perfusion and sequential cell seeding replicate the physiological bone remodeling process in vitro, enabling the long‐term culture of functional, mature bone marrow immune subpopulations.

Modulation of miR‐23b Wnt/β‐catenin Axis Strengthens Endothelial Barrier Properties

Advanced Science, EarlyView.
Early blood‐brain barrier (BBB) disruption contributes to stroke and CNS disease pathology. miR‐23b was identified as a regulator of BBB integrity in brain endothelial cells. Inhibition of miR‐23b enhanced barrier‐associated properties, promoted repair‐related signaling, and reduced BBB leakage in experimental stroke models, supporting further ...

A Toolkit for Targeted Neuromodulation of Striatal Direct Pathway Neurons Rescues Parkinsonian Motor Deficits in Mice

Advanced Science, EarlyView.
An adeno‐associated virus (AAV) toolkit enables selective anatomical and functional targeting of striatal D1‐MSNs through retrograde transduction. Enhanced capsids and engineered enhancers drive robust transgene expression across murine and primate models.

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

Vasoactive Peptides and Their Receptors

Blood Vessels, 2008
Peptides act as vasoconstrictors (for instance angiotensins, vasopressin) or vasodilators (the kinins, the neurokinins), both through direct activation of specific receptors in the vascular smooth muscles or indirectly through the release of other endogenous inhibitors of the vascular tone.

Kinins and peptide receptors

Biological Chemistry, 2016
AbstractThis paper is divided into two sections: the first contains the essential elements of the opening lecture presented by Pr. Regoli to the 2015 International Kinin Symposium in S. Paulo, Brazil on June 28th and the second is the celebration of Dr. Regoli’s 60 years of research on vasoactive peptides.

Opioid Peptides and their Receptors

1982
The three agonists, methionine-enkephalin, leucine-enkephalin and beta-endorphin have different pharmacological patterns. It may be of particular importance that they vary in their relative affinities to the enkephalin and naltrexone binding sites in the brain; the former are probably related to delta-receptors prevalent in the mouse vas deferens and ...

Peptide Receptors on Astrocytes

Frontiers in Neuroendocrinology, 1998
In recent years, it has become apparent that astrocytes (at least in vitro) harbor functional receptors to almost all possible neurotransmitters (with the potential noticeable exception of acetylcholine nicotinic receptors). Peptides are no exception, since receptors to all neuropeptides known to be produced in the CNS have been found on cultured ...

Peptide Hormone Receptors

1991
A large number of peptide hormones have been identified and are known to elicit a wide variety of biological responses from target cells throughout the body. These hormones exert their effects by interaction with receptors which are integral components of the cell surface membrane.

Peptide Receptors in the Airways

American Review of Respiratory Disease, 1987
Abstract Two categories of peptides exert opposing effects on the isolated guinea pig trachea. Neurokinins (substance P [SP] and congeners) provoke contraction, and kinins (bradykinin) provoke relaxation. Both peptide categories promote the release of relaxing prostaglandins that oppose the contractions induced by neurokinins and ...
