Interneurons in area CA1 stratum radiatum and stratum oriens remain functionally connected to excitatory synaptic input in chronically epileptic animals.
Past work has demonstrated a reduction of stimulus-evoked inhibitory input to hippocampal CA1 pyramidal cells in chronic models of temporal lobe epilepsy (TLE). It has been postulated that this reduction in inhibition results from impaired excitation of inhibitory interneurons. In this report, we evaluate the connectivity of area CA1 interneurons to their excitatory afferents in hippocampal-par...
متن کاملDifferential involvement of oriens/pyramidale interneurones in hippocampal network oscillations in vitro.
Using whole-cell patch-clamp recordings in conjunction with post hoc anatomy we investigated the physiological properties of hippocampal stratum oriens and stratum pyramidale inhibitory interneurones, before and following the induction of pharmacologically evoked gamma frequency network oscillations. Prior to kainate-induced transient epochs of gamma activity, two distinct classes of oriens int...
متن کاملVariable kainate receptor distributions of oriens interneurons.
Interneuron kainate receptor (KAR) activation regulates normal network activity and modulates cell excitability. As a result, determining the subcellular distribution of KARs in a cell-specific manner is a necessary step toward understanding their role in network function. We have functionally mapped synaptic and extrasynaptic dendritic KARs on hippocampal oriens interneurons using local photol...
متن کاملMembrane potential and intracellular Ca2+ oscillations activated by mGluRs in hippocampal stratum oriens/alveus interneurons.
Metabotropic glutamate receptors (mGluRs) are expressed heterogeneously in hippocampal interneurons, and their signal transduction cascades remain largely unclear. We characterized an oscillatory response activated by the mGluR agonist 1S,3R-1-aminocyclopentane-1,3-dicarboxylic acid (1S,3R-ACPD) in hippocampal interneurons of stratum oriens-alveus (OA) with simultaneous whole cell current-clamp...
متن کاملMetabolism Fine-tunes Macrophage Activation
C ells continually monitor the availability of nutrients and alter their activities and metabolism accordingly. Immune cells are no exception (O’Neill and Pearce, 2015). Macrophages are important immune cells that perform many roles – they are, for example, involved in development and wound repair – but they need to be activated before they can carry out their functions. For years it was though...
