The contents of the mRNAs encoding the γ‐and ϵ‐subunits of the nicotinic acetylcholine
receptor as well as the single‐channel properties of the receptor have been assessed in
innervated, denervated and reinnervated rat muscle. The changes in abundance of the γ‐
and ϵ‐subunit mRNAs correlate with the changes in relative density of two classes of
acetylcholine receptor channels. The results support the view that a switch in the relative
