Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

The Role of Nicotinic Receptors on Ca²⁺ Signaling in Bovine Chromaffin Cells

Current Issues in Molecular Biology
Chromaffin cells have been used as a physiological model to understand neurosecretion in mammals for many years. Nicotinic receptors located in the cells’ membrane are stimulated by acetylcholine, and they participate in the exocytosis of chromaffin ...

Distribution of α7 Nicotinic Acetylcholine Receptor Subunit mRNA in the Developing Mouse. [PDF]

, 2019
Homomeric α7 nicotinic acetylcholine receptors (nAChRs) are abundantly expressed in the central and peripheral nervous system (CNS and PNS, respectively), and spinal cord.

Regions of beta 2 and beta 4 responsible for differences between the steady state dose-response relationships of the alpha 3 beta 2 and alpha 3 beta 4 neuronal nicotinic receptors [PDF]

, 1995
We constructed chimeras of the rat beta 2 and beta 4 neuronal nicotinic subunits to locate the regions that contribute to differences between the acetylcholine (ACh) dose-response relationships of the alpha 3 beta 2 and alpha 3 beta 4 receptors ...

Pathways for nicotinic receptor desensitization [PDF]

Journal of General Physiology, 2020
Nicotinic acetylcholine receptors (AChRs) are ligand-gated ion channels that generate transient currents by binding agonists and switching rapidly between closed- and open-channel conformations. Upon sustained exposure to ACh, the cell response diminishes slowly because of desensitization, a process that shuts the channel even with agonists still bound.

Mesenchymal Stromal Cell Secretome and Its Key Bioactive Metabolites Induce Long‐Term Neuroprotection After Traumatic Brain Injury in Mice

Advanced Science, EarlyView.
Pischiutta F and coworkers identify prostaglandins and kynurenine as key mediators of the mesenchymal stromal cells‐derived secretome's neuroprotective effects. A synthetic cocktail composed of these factors promotes long‐term functional recovery, reduces brain structural damage, and modulates neuroinflammation after traumatic brain injury, supporting ...

Apoptotic Bodies Restore NAD and Mitochondrial Homeostasis in Fibroblasts

Advanced Science, EarlyView.
Mesenchymal stem cell‐derived apoptotic bodies (MSC‐ABs) target keloid fibroblasts (KFs), restoring nicotinamide adenine dinucleotide (NAD) metabolism and mitochondrial function, suppressing collagen overproduction, and rebalancing tissue homeostasis, offering a novel therapy for keloid.

Venom-Derived Neurotoxins Targeting Nicotinic Acetylcholine Receptors

Molecules, 2021
Acetylcholine was the first neurotransmitter described. The receptors targeted by acetylcholine are found within organisms spanning different phyla and position themselves as very attractive targets for predation, as well as for defense. Venoms of snakes
