Biochem/physiol Actions

SEM308 is a pharmacologically selective effector molecule (PSEM) that acts as a selective agonist in vitro and in vivo for chimeric pharmacologically selective actuator modules (PSAMs) composed of nAChR α7 ligand-binding domain (LBD) with L141F or L141F/Y115F mutation fused to the ion pore domain (IPD) of a ligand-gated ion channel (LGIC), including glycine receptor (PSAML141F-GlyR & PSAML141F/Y115F-GlyR) and 5-HT3 (PSAML141F/Y115F-5-HT3).

Translating the behavioural output of the nervous system into movement involves interaction between brain and spinal cord. The brainstem provides an essential bridge between the two structures, but circuit-level organization and function of this intermediary system remain poorly understood. Here

Dysfunctional breathing is the main cause of morbidity and mortality after traumatic injury of the cervical spinal cord1,2 and often necessitates assisted ventilation, thus stressing the need to develop strategies to restore breathing. Cervical interneurons that form synapses on phrenic

Excessive excitation has been hypothesized to subsume a significant part of the acute damage occurring after traumatic brain injury (TBI). However, reduced neuronal excitability, loss of neuronal firing, and a disturbed excitation/inhibition balance have been detected. Parvalbumin (PV) interneurons are

Convergent input from different presynaptic partners shapes the responses of postsynaptic neurons. Whether developing postsynaptic neurons establish connections with each presynaptic partner independently or balance inputs to attain specific responses is unclear. Retinal ganglion cells (RGCs) receive convergent input from

How does coordinated activity between distinct brain regions implement a set of learning rules to sculpt information processing in a given neural circuit? Using interneuron cell-type-specific optical activation and pharmacogenetic silencing in vitro, we show that temporally precise pairing of
