Rabbit sinoatrial node cells exhibit heterogeneous, size-dependent connexin expression, suggesting potential heterotypic or heteromeric channels at the node periphery.
No takes yet. Share an insight, caveat, or question.
No immediate clinical implications for nodal arrhythmias; leaves open functional roles of heteromeric connexin channels in SAN conduction.
H. Honjo (2002) studied this question.
