Neuronal Nicotinic Acetylcholine Receptor Modulators from Cone Snails

Marine Drugs, 2018
Marine cone snails are a large family of gastropods that have evolved highly potent venoms for predation and defense. The cone snail venom has exceptional molecular diversity in neuropharmacologically active compounds, targeting a range of receptors, ion

Extracellular Vesicle Packaged TDP43 Derived From ECs Exacerbates Cigarette Tar‐Related Atherosclerosis Progression via Enhancing Macrophage Extracellular Traps

Advanced Science, EarlyView.
Cigarette tar triggers EC‐derived EVs carrying TDP43, which binds VDAC1 to boost MAMs, mitochondrial Ca2+ overload, and METs formation in macrophages, accelerating smoking‐related AS progression, while retinoic acid binds TDP43 to block this pathogenic cascade.

One‐Year Healthcare Utilization and Costs After Emergency Department Encounters for Uncomplicated Appendicitis: A Statewide Observational Study

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Objective Non‐operative management with antibiotics has emerged as an alternative to appendectomy for uncomplicated appendicitis. This study compared one‐year healthcare costs and utilization outcomes after operative versus non‐operative management of uncomplicated appendicitis using statewide administrative data.

Transitioning to nonpunitive school policies for addressing student substance use: Qualitative interviews with key school administrators

American Journal of Community Psychology, EarlyView.
Abstract Recent policy change in Massachusetts encourages schools to limit their use of exclusionary discipline to “extraordinary circumstances,” but little work has explored the opportunities and challenges of transitioning to nonpunitive practices after student substance use infractions in schools.

Neurotransmitter‐Defined Degeneration Patterns in Sporadic and C9orf72‐Associated Amyotrophic Lateral Sclerosis: Predilection to GABAergic, Serotonergic, Opioid, Glutamatergic, Endocannabinoid, and Microglial Systems—Implications for Therapy Development

Annals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a markedly distinctive clinical and neuroradiological signature, with the preferential involvement of specific brain networks and the apparent sparing of others. The molecular underpinnings of the strikingly selective anatomical vulnerability have not been fully elucidated to date despite the potential ...

Characterization of nAChRs in Nematostella vectensis supports neuronal and non-neuronal roles in the cnidarian–bilaterian common ancestor

EvoDevo, 2019
Background Nicotinic and muscarinic acetylcholine receptors likely evolved in the cnidarian–bilaterian common ancestor. Both receptor families are best known for their role at chemical synapses in bilaterian animals, but they also have described roles as

Reframing the Gut–Brain Axis: The Gut Wall as a Neural Immune Interface in Multiple Sclerosis and Autoimmune Neurological Diseases

Annals of Neurology, EarlyView.
Gut wall physiology in multiple sclerosis (MS) and autoimmune neurologic diseases remains underexplored but may span gut barrier dysfunction, enteric glial targeting, mucosal immune dysregulation, and autoimmune targets within the enteric nervous system (ENS).
