A key role for E-cadherin in intestinal homeostasis and Paneth cell maturation.
<h4>Background</h4>E-cadherin is a major component of adherens junctions. Impaired expression of E-cadherin in the small intestine and colon has been linked to a disturbed intestinal homeostasis and barrier function. Down-regulation of E-cadherin is associated with the pathogenesis of in...
