Voltage-gated K channels of the Kv2 family coassemble with electrically silent KvS subunits in specific subpopulations of brain neurons, forming heteromeric Kv2/KvS channels with distinct functional properties. Little is known about the composition and function of Kv2 channels in spinal cord neurons, however. Here, we show that while Kv2.

Introduction: The α-adrenoceptor (αAR) is involved in the physiopathology of the central nervous system (CNS), but its function in the adult male rat locus coeruleus (LC) has not been fully studied. We aimed to characterize the role of the αAR in the regulation of the firing rate (FR) of LC neurons and to describe the signaling pathways involved.
Methods: We measured, through single-unit extracellular recordings of LC neurons from adult male rats were used to measure the effect of adrenergic agonists in the presence and absence of adrenergic antagonists or inhibitors of several signalling pathways.

ObjectivesThe objective of this study was to evaluate the occurrence of voltage-gated potassium channel (VGKC) antibodies and the pattern of MRI changes in cats with complex partial seizures with orofacial involvement (CPSOFI), as well as to investigate whether there are factors influencing survival that could be used as prognostic markers in those cats.MethodsCats with CPSOFI were identified retrospectively. The following data were retrieved from the hospital database: signalment, age at first seizure and presentation, the presence of antibodies against VGKC (leucine-rich glioma inactivating factor 1 (LGI1), contactin-associated protein 2 (CASPR2)) and cerebrospinal fluid (CSF) analysis findings.

This study investigated the effects of soy isoflavone yeast fermented extract (soyF) and soy isoflavone yeast unfermented extract (soyN) on rat ileal smooth muscle contraction. SoyF and soyN inhibited carbachol (CCh)- or KCl-induced contraction in a concentration-dependent manner; however, these effects were stronger for CCh-induced contraction than that for KCl, and the relaxation effect was stronger for soyF than for soyN. SoyF-induced relaxation was attenuated by 4-aminopyridine (4-AP), a Kv channel inhibitor, and iberiotoxin (IbTX), a calcium-activated potassium channel (BK channel) inhibitor.

Repeated exposure to gestational general anesthesia during pregnancy has been associated with neurodevelopmental damage and cognitive and social dysfunction in offspring. This study investigates the underlying mechanisms and therapeutic strategies for mitigating these effects. Behavioral tests revealed significant impairments in cognitive, social, and spatial learning abilities in the offspring of general anesthesia-treated mice, alongside delayed eye-opening, reduced body weight, and neuronal damage.
