Fig. 2From: A hypothesis of couplet molecules and couplet cells in gastric function and an association with Helicobacter pylori A Possible Complex Interaction of a G-Cell and an ECL Cell. The reciprocal interactions of a G-Cell and an ECL Cell (GC and ECLC) are illustrated as in Fig. 1. In addition, this model incorporates a possible extracellular receptor for the Gastrin:Histamine complex (the CC in this particular case)Back to article page
