چکیده

Ion channel models are the building blocks of computational neuron models. Their biological fidelity is therefore crucial for the interpretation of simulations. However, the number of published models, and the lack of standardization, make the comparison of ion channel models with one another and with experimental data difficult. Here, we present a framework for the automated large-scale classification of ion channel models. Using annotated metadata and responses to a set of voltage-clamp protocols, we assigned 2378 models of voltage- and calcium-gated ion channels coded in NEURON to 211 clusters. The IonChannelGenealogy (ICGenealogy) web interface provides an interactive resource for the categorization of new and existing models and experimental recordings. It enables quantitative comparisons of simulated and/or measured ion channel kinetics, and facilitates field-wide standardization of experimentally-constrained modeling.

O 13: Ion Channels in Autoimmune Neurodegeneration

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system characterized by widespread inflammation, focal demyelination and a variable degree of axonal and neuronal loss. Ionic conductances regulate T cell activation as well as neuronal function and thus have been found to play a crucial role in MS pathogenesis. Since present therapeutical approaches are only parti...

P 44: The Role of HCN Channels in T Cell Function

Ion channels play a major role in the regulation of T cell function in health and disease. In a computer-based model, established to simulate T cells’ membrane potential (VM) generation, we discovered a discrepancy between the simulation and patch-clamp recordings. The predicted VM was more hyperpolarized than the measured VM, indicating that a yet unknown, depolarizing ion current might ...

Simulation study of the transport properties of ions through ion channels serving as primary components of a nanobiosensor

Ion channels are naturally occurring pores through the proteins that regulate the passage of ions and thus maintain the concentration of ions inside and outside the cell. The ion channels control many physiological functions and they can show selectivity for a specific ion. Ion channels are mostly observed in nerve cells and muscle cells. The influx of ions into cells can be regulated by a gate...

Electrophysiological investigation of the cellular effect of anethole, the chief constitute of anise, on F1 neuronal excitability in garden snail

Introduction: Anethole is the main constituent of Pimpinella anisum L. (anise), a herbaceous annual plant which has several therapeutic effects. In the folk medicine, anise is employed as an antiepileptic drug. Specifically, this study was focused on the cellular effect of anethole, an aromatic compound in essential oils from anise and camphor. Anethole has various physiological effects on t...
