MCT2 is selectively expressed by Purkinje cell subsets.

<p><b>A:</b> Levels of MCT2 immunoreactivity vary between Purkinje cell somata of the Purkinje cell layer (pcl) from strong (white arrowhead), to weak (black arrow), to none (black arrowhead). No boundaries are seen in the granular layer (gl). <b>B:</b> Clear boundaries are seen in the molecular layer (ml) between regions that express high levels of MCT2 immunoreactivity and others that are either weakly reactive or unreactive (arrows). <b>C:</b> A transverse section through lobule VIa of the adult rat cerebellar cortex double immunofluorescence labelled for zebrin II/aldolase C (green) and MCT2 (red), showing an array of alternating Purkinje cell stripes. The stripes of MCT2 immunoreactivity alternate with those of zebrin II/aldolase C. Scale bars: A and C = 50 µm, B = 100 µm.
