The IgG4/IgG1 ratio in the liver may be a useful marker for differential diagnosis of IgG4-SC and PSC. In IgG4-SC, abundant infiltration of regulatory T cells (Tregs) may affect the switching of B cells to IgG4-producing plasmacytes, and there is a possibility that the function of Tregs is different in IgG4-SC and other liver diseases (PSC, AIH, and PBC).

ADSCs can accelerate the regeneration of injured regions in experimental colitis. HGF, VEGF, and adiponectin might be responsible for the regeneration of injured regions in the colon.

As with chronic pancreatitis patients, AIP patients should be observed closely for abnormality in pancreatic function.
