Expression patterns of activins and activin receptors in the duct epithelial cells in the pancreas of NOD and IFN-γ transgenic mice

βA subunit++++
βB subunit++++
Type II receptor+++
Type IIB receptor+++
Type I receptor+/−
Type IB receptor++
  • Pancreatic sections were stained with antibodies against βA and βB subunits and type II, type IIB, type I, and type IB activin receptors. +, moderate expression; +++, very high expression; +/−, very low expression; −, expression was not detected by immunohistochemistry.
