Neuromodulator Dynamics Underlying Associative Learning in the Ventral Striatum's Olfactory Tubercle

Advanced Science, EarlyView.
Using fiber photometry and genetically encoded sensors, the dynamic release patterns of four neuromodulators in the olfactory tubercle (OT)—a brain region overlapping with the olfactory cortex and ventral striatum—were systematically monitored in response to external rewards and distinct reward‐associated learning processes.

Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

Advanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

“Augmented Reality” in Martial: The Use and the Abuse of Olfactory and Gustatory Systems in Martial’s Epigrams

Humanitas
This paper examines Martial's innovative use of the senses of smell and taste in his epigrams, revealing how he transcends the limitations of the written word by inviting readers to interact with his work on a visceral level.

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

Advanced Science, EarlyView.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Reprogramming Antitumor Immunity: NK Cell Strategies to Navigate the Immunosuppressive Tumor Microenvironment

Advanced Science, EarlyView.
ABSTRACT Tumor immune escape is a major barrier to durable cancer immunotherapy, as advanced malignancies create a tumor microenvironment (TME) that preferentially exhausts and disables T cell responses. While most approved cell therapies are T cell‐based, this limitation motivates the exploration of an alternative effector cell platform.

Size-Dependent Deposition, Translocation, and Microglial Activation of Inhaled Silver Nanoparticles in the Rodent Nose and Brain. [PDF]

, 2016
BackgroundSilver nanoparticles (AgNP) are present in personal, commercial, and industrial products, which are often aerosolized. Current understanding of the deposition, translocation, and health-related impacts of AgNP inhalation is limited.ObjectivesWe

Paternal Caffeine Exposure Programs Offspring Stress Vulnerability via Sperm Dlk1‐Dio3 Imprinting‐Directed Remodeling of a Novel Neural Circuit

Advanced Science, EarlyView.
The study elucidates that paternal preconception stress can drive offspring hyperresponsivity of the stress system via hypomethylation of a specific DNA region in sperm. This key link is confirmed in a cohort of prospective fathers: the epigenetic alteration is associated with elevated stress hormone levels.

Ethical and Frugal Approaches to Animal Experimentation in Bioelectronics and Neural Engineering—An Invertebrate Renaissance?

Advanced Electronic Materials, EarlyView.
Invertebrates are the classic neuroscience models and should make a comeback. Invertebrate organisms can be a more ethical and cost‐effective way to move bioelectronics research forward more rapidly. ABSTRACT The accelerating development of bioelectronic neural interfaces has brought increased attention to ethical considerations surrounding in vivo ...

Reduced CB1 Cannabinoid Receptor Expression in Alzheimer's Disease and Transgenic Mouse Models

AGING MEDICINE, EarlyView.
CB1 receptor (CB1R) expression was significantly reduced in the hippocampus, medial frontal gyrus, and superior temporal gyrus of Alzheimer's patients. CB1R levels negatively correlated with amyloid‐β and tau pathology. In addition, CB1R expression was also reduced in the cortex of 5xFAD mice and in the hippocampus of Tg4‐42 mice.
