1. The Vaseline-gap voltage clamp technique was used to record dihydropyridine (DHP)-sensitive Ca2+ currents (ICa) and charge movement in single cut fibres from the rat extensor digitorum longus (EDL) muscle. Amyotrophic lateral sclerosis (ALS) immunoglobulin G (IgG) action on ICa and charge movement has been characterized. 2. ALS IgG reduced ICa amplitude. The peak ICa of EDL fibres (mean +/- S.E.M.) at 0 mV, expressed as amperes per membrane capacitance, was -4.79 +/- 0.029 A F-1, while after… CONTINUE READING
