Upregulated expression and function of VLA 4 fibronectin receptors on human activated T cells in rheumatoid arthritis . ^^^ We have investigated the expression and function of VLA 4 fibronectin ( FN ) receptors on T cells localized in the inflammed synovium of patients with rheumatoid arthritis ( RA ) . ^^^ Furthermore , the majority of these activated SF T cells were able to adhere to a 38 kD FN proteolytic fragment containing the connecting segment 1 ( CS 1 ) specifically through VLA 4 receptors , whereas a significantly lower proportion of PB T cells displayed this capacity . ^^^ |

The induced expression of VLA 4 after activation of tonsillar B lymphocytes was accompanied by the acquisition of the capacity to bind to a 38 kDa proteolytic fragment , containing the connecting segment 1 domain , of FN . ^^^ Interestingly , nonactivated peripheral blood B cells were unable to attach to this FN fragment , in spite of their constitutive expression of VLA 4 , and only acquired this functional capacity after cell activation with phorbol esters and SAC . ^^^ These results underline that the FN binding activity of VLA 4 is dependent on processes affecting cellular activation as described for other members of the integrin family . ^^^ |

We have previously shown that normal CD34+ HPCs express high levels of fibronectin ( Fn ) receptors very late antigen 4 ( VLA 4 ) and VLA 5 in a low affinity state , which do not allow HPCs to strongly adhere on immobilized Fn , and that cytokines such as interleukin 3 , granulocyte monocyte colony stimulating factor , and stem cell factor transiently activate these receptors , providing HPCs with an adhesive phenotype on Fn . ^^^ Therefore , we propose a 2 step model with an initial activation of VLA 4 and VLA 5 generated by cytokine receptors that is followed by a secondary signal resulting from Fn binding to VLA 4 and VLA 5 , which may cooperate with those generated by cytokine receptors . . ^^^ |
