Immunolocalization of membrane skeletal protein, 4.1G, in enteric glial cells in the mouse large intestine

▶ Protein 4.1G is strongly immunolocalized in Auerbach's myenteric plexus. ▶ It is mostly colocalized with glial fibrillary acidic protein. ▶ It is ultrastructually detected along cell membranes of glial processes around axons. ▶ Nerve fiber networks are also immunostained for 4.1G protein.
