WebSep 15, 2010 · It is notable that even potent antagonism of these mechanisms rarely causes temperature elevation and that multiple mechanisms, including the acute phase response, stress-induced hyperthermia, drugs effects, etc., involving compounding interactions, are required to precipitate hyperthermia. In a large proportion (50–70%) of cases, the propensity for malignant hyperthermia is due to a mutation of the ryanodine receptor (type 1), located on the sarcoplasmic reticulum (SR), the organelle within skeletal muscle cells that stores calcium. RYR1 opens in response to conformational changes in the L-type calcium channels following membrane depolarisation, thereby resulting in a drastic increase in intracellular calcium levels and muscle contraction. RYR…
