Hace 5 días · Neural crest cells are a temporary group of cells that arise from the embryonic ectoderm germ layer, and in turn give rise to a diverse cell lineage—including melanocytes, craniofacial cartilage and bone, smooth muscle, peripheral and enteric neurons and glia.
Hace 2 días · Adrenaline causes liver cells to release glucose into the blood, acting through both alpha and beta-adrenergic receptors to stimulate glycogenolysis. Adrenaline binds to β 2 receptors on liver cells, which changes conformation and helps G s, a heterotrimeric G protein, exchange GDP to GTP.
Hace 3 días · Interneurons are the central nodes of neural circuits, enabling communication between sensory or motor neurons and the central nervous system (CNS). They play vital roles in reflexes , neuronal oscillations , [3] and neurogenesis in the adult mammalian brain.
Hace 2 días · Lee et al. study the impact of oscillatory electric fields on neuronal activity across different cell types, brain regions, and species. Electric fields strongly entrain both cellular subthreshold responses and spike timing and phase, with entrainment properties being stimulation frequency and cell class specific across areas.
Hace 5 días · NervGen (TSX-V: NGEN, OTCQX: NGENF) is a clinical stage biotech company dedicated to developing innovative treatments that enable the nervous system to repair itself following damage, whether due to injury or disease.
Hace 5 días · Nerve cells can release GABA or glycine where they contact other nerve cells at junctions called synapses. This typically prevents further signal transmission by the post-synaptic cell.
Hace 5 días · Now, a team led by researchers from Brigham and Women's Hospital, has shown that a specific astrocyte sub-population can do the opposite, instead serving a protective, anti-inflammatory function ...
