Postinjury tissue inflammation with PMN elastase proteolysis generates immunosuppressive fibronectin peptides (FNDP) impairing chemotaxis, T-cell activation, and proliferation. Excess intracellular Ca2+ ([Ca2+]i) impairs T-cell activation. This study quantifies the changes in [Ca2+]i following exposure to a degradation peptide of fibronectin to determine the mechanism of action of these peptides on calcium homeostasis. Isolated human PBLs were exposed to immunosuppressive concentrations of FNDP… CONTINUE READING
