We show here that soluble TN inhibits proliferation of human T cells in response to alpha CD3 Ab co-immobilized with the extracellular matrix protein fibronectin ( FN ).
 ( protein: CD3, None) , ( protein: TN, None) , ( protein: fibronectin, None) , ( protein: extracellular matrix protein, None) , ( protein: alpha CD3 Ab, None) , ( protein: FN, None) , ( cell type: human T cells, None)
