Does not warrant changes in clinical nicotinic therapies; extends basic mapping of human α3 AChR subtypes in cell models.
The single-channel properties of human alpha3 AChRs are determined by their subunit composition, demonstrating that native IMR-32 receptors are primarily alpha3beta4 AChRs.
Nelson et al. (1999) studied this question. Subunit composition of human α3 AChRs was evaluated on Single channel properties (open times, conductance, burst times). Human α3 AChRs exhibit distinct single-channel properties depending on subunit composition, with native IMR-32 receptors primarily resembling α3β4 AChRs.
