GIRK1 and -2 co-exist with neuronal markers in control DRGs. A GIRK1 co-exists with CGRP, IB4 or NF200, whereas GIRK2 only co-exists with IB4 or NF200. Arrowheads indicate co-existence of GIRKs with respective markers. B1 Percentage co-existence of GIRK1+ and -2+ NPs with CGRP, IB4 or NF200. B2 Percentage co-existence of CGRP+, IB4+ or NF200+ NPs with GIRKs. C Fluorescence intensity plotted vs. cross-sectional area of GIRK1+ neurons. D Fluorescence intensity plotted vs. cross-sectional area of GIRK2+ neurons. Scale bar indicates 40 μm (A, valid for all).
