Immunohistochemistry in rat trigeminal ganglion. (A) Trigeminal ganglion neurons in the ophthalmic division immunoreactive for insulin receptor (InsR), TRPV1 receptor and CGRP. (B) Coexpression of insulin receptor (InsR) with TRPV1 receptor and/or CGRP in trigeminal ganglion neurons. Colours representing insulin receptor-, TRPV1 receptor- and CGRP-immunoreactivities and their coexpressions indicated in B applies also to A. (C) A trigeminal ganglion neuron retrogradely labeled with True blue expresses both insulin receptor (InsR) and TRPV1 receptor
