Structural basis for ryanodine receptor type 2 leak in heart failure and arrhythmogenic disorders [PDF]
Heart failure, the leading cause of mortality and morbidity in the developed world, is characterized by cardiac ryanodine receptor 2 channels that are hyperphosphorylated, oxidized, and depleted of the stabilizing subunit calstabin-2.

Activating ryanodine receptor improves isoflurane-induced cognitive dysfunction
Background: Postoperative cognitive dysfunction (POCD) is characterized by impaired learning and memory. 6 h duration isoflurane anesthesia is an important factor to induce POCD, and the dysfunction of ryanodine receptor (RyR) in the hippocampus may be ...

Muscle-specific Ryanodine receptor 1 properties underlie limb-girdle muscular dystrophy 2B/R2 progression [PDF]
Ryanodine receptor 1 Ca2+ leak is a signal in skeletal muscle, but chronic leak can underlie pathology. Here we show that in healthy male mouse, limb-girdle muscle presents higher sympathetic input, elevated ryanodine receptor 1 basal phosphorylation ...

Cryo-EM investigation of ryanodine receptor type 3 [PDF]
Ryanodine Receptor isoform 3 (RyR3) is a large ion channel found in the endoplasmic reticulum membrane of many different cell types. Within the hippocampal region of the brain, it is found in dendritic spines and regulates synaptic plasticity.

Disparate molecular mechanisms in cardiac ryanodine receptor channelopathies [PDF]
AimsMutations in the cardiac ryanodine receptor (RyR2) are associated with catecholaminergic polymorphic ventricular tachycardia (CPVT). This study investigates the underlying molecular mechanisms for CPVT mutations within the RyR2 N-terminus domain (NTD)

Abstract Excitation-contraction coupling involves the faithful conversion of electrical stimuli to mechanical shortening in striated muscle cells, enabled by the ubiquitous second messenger, calcium. Crucial to this process are ryanodine receptors (RyRs), the sentinels of massive intracellular calcium stores contained within the sarcoplasmic ...

Calcium Homeostasis in Myogenic Differentiation Factor 1 (MyoD)-Transformed, Virally-Transduced, Skin-Derived Equine Myotubes [PDF]
Dysfunctional skeletal muscle calcium homeostasis plays a central role in the pathophysiology of several human and animal skeletal muscle disorders, in particular, genetic disorders associated with ryanodine receptor 1 (RYR1) mutations, such as malignant

Ryanodine Receptors Selectively Interact with L Type Calcium Channels in Mouse Taste Cells. [PDF]
INTRODUCTION:WE REPORTED THAT RYANODINE RECEPTORS ARE EXPRESSED IN TWO DIFFERENT TYPES OF MAMMALIAN PERIPHERAL TASTE RECEPTOR CELLS: Type II and Type III cells. Type II cells lack voltage-gated calcium channels (VGCCs) and chemical synapses.
