Intrinsic factor (IF) is a glycoprotein that is secreted by parietal cells in the stomach lining which binds to vitamin B12 in the small intestine and enables its absorption. In pernicious anemia, the body produces autoimmune antibodies against IF. The loss of IF inhibits the small intestine’s ability to absorb vitamin B12, resulting in vitamin B12 deficiency.
