A humanized Gs-coupled DREADD for circuit and behavior modulation.

Designer receptors exclusively activated by designer drugs (DREADDs) play important roles in neuroscience research and show great promise for future clinical interventions in neurological diseases. The Gs-coupled DREADD, rM3Ds, modulates excitability in neuron subsets that are sensitive to downstream effectors of Gs protein. However, given the non-human nature of the rM3Ds backbone, risks about potential immunogenicity and tolerability exist when considering clinical translation.

Peripheral nervous system microglia-like cells regulate neuronal soma size throughout evolution.

Microglia, essential in the central nervous system (CNS), were historically considered absent from the peripheral nervous system (PNS). Here, we show a PNS-resident macrophage population that shares transcriptomic and epigenetic profiles as well as an ontogenetic trajectory with CNS microglia. This population (termed PNS microglia-like cells) enwraps the neuronal soma inside the satellite glial cell envelope, preferentially associates with larger neurons during PNS development, and is required for neuronal functions by regulating soma enlargement and axon growth.

Real-time visualization of epileptic seizures using photoacoustic imaging with a peroxynitrite-responsive manganese(ii) texaphyrin.

Real-time visualization and tracking of epileptic seizures are important for studying epilepsy pathogenesis and treating epilepsy; however, the requisite sensing is extremely challenging, primarily due to the transient and intricate nature of neural activity associated with epilepsy. The onset of epilepsy is closely correlated with increases in peroxynitrite (ONOO) levels, a reactive nitrogen species that can serve as a biomarker for epilepsy. However, the fleeting biological half-life and high reactivity of ONOO has historically impeded its direct visualization within the epileptic brain.
