Regulating Cells Fate and Function to Facilitate Bone Regeneration via Designing Programmable Bio‐Interactive Materials

open access: yesAdvanced Science, EarlyView.
This article aims to elucidate the biological mechanisms of bone repair and the evolution of material design, highlighting key cellular and molecular processes. It further proposes strategies and prospects for programmable bio‐interactive materials, which enable precisely guided bone tissue regeneration by dynamically regulating cell behavior and the ...

Changes in conformation and subcellular distribution of alpha(4)beta(2) nicotinic acetylcholine receptors revealed by chronic nicotine treatment and expression of subunit chimeras [PDF]

open access: yes, 2002
Chronic exposure to nicotine, as occurs during tobacco smoking, is one of several factors that have been reported to cause an upregulation of neuronal nicotinic acetylcholine receptors (nAChRs).

Early Spatial and Contextual Coding Deficits in Hippocampal CA1 Precede Performance Decline in an Alzheimer's Disease Model

open access: yesAdvanced Science, EarlyView.
Two‐photon calcium imaging in behaving 5xFAD mice reveals early CA1 coding deficits before behavioral decline. Task‐related place cell activity and splitter cell trajectory coding are impaired, with reduced retrospective dominance and greater prospective weighting.

Layer- and Cell Type-Specific Modulation of Excitatory Neuronal Activity in the Neocortex

open access: yesFrontiers in Neuroanatomy, 2018
From an anatomical point of view the neocortex is subdivided into up to six layers depending on the cortical area. This subdivision has been described already by Meynert and Brodmann in the late 19/early 20.

Acetylcholine-treated murine dendritic cells promote inflammatory lung injury

open access: yes, 2019
In recent years a non-neuronal cholinergic system has been described in immune cells, which is often usually activated during the course of inflammatory processes. To date, it is known that Acetylcholine (ACh), a neurotransmitter extensively expressed in

Enteric ChAT‐Expressing Neurons Mediate the Protective Effect of Lactobacillus plantarum in Inflammatory Bowel Disease

open access: yesAdvanced Science, EarlyView.
In colitis patients and mice, reduced Lactobacillus abundance is observed. Experimental studies show that L. plantarum A736 metabolizes dietary tryptophan into indole‐3‐lactic acid (ILA), while both L. plantarum A736 and ILA impact ChAT‐expressing enteric neurons and acetylcholine levels, thereby regulating intestinal immune responses and alleviating ...

Sequential Design of Activatable Photosensitizers for Ablation of Glioma Cells in Brain Cancer Tissues

open access: yesAngewandte Chemie, EarlyView.
Gal‐SeNBD‐oleamide is an activatable photosensitizer (PS) with efficient uptake and selective, β‐galactosidase‐triggered activation in cancer cells, enabling efficient photodynamic ablation of glioma cells directly in brain tissue slices from mouse preclinical models and human glioblastoma patients.

Inhibitory Effect of Ginkgo Biloba Extract on the Tonus of the Small Intestine and the Colon of Rabbits

open access: yesMolecules, 2010
Ginkgo biloba is widely used in folk medicine. Patients very often use the plant preparation with no concern for purity. They also tend to increase the dosage by themselves and this may result in certain insufficiently researched acute effects.

Macrophage Dab1 Links Early Hypoxia to Adaptive Angiogenesis to Drive Peripheral Nerve Repair

open access: yesAdvanced Science, EarlyView.
Schematic diagram illustrating the Dab1‐linked hypoxia signaling pathway that accelerates angiogenesis and consequent nerve regeneration. Following PNI, a hypoxic microenvironment develops. Hypoxia induces macrophage Dab1 phosphorylation, resulting in NHE‐1 upregulation, HIF‐1α stabilization, and VEGF‐A expression. This cascade promotes angiogenesis in

Acetylcholine- and sodium nitroprusside-dilation in APL3W, CT3W and HCQ3W.

open access: yes, 2018
Influence of sex. Effects of monoclonal anti-beta-2-GPI antibody (aB2GPI) on dilation responses expressed as percentage of relaxation to acetylcholine (ACh) and sodium nitroprusside (SNP) in mice mesenteric arteries.
