From: Th1 type lymphocyte reactivity to metals in patients with total hip arthroplasty
The graphical results show the averaged (and individual normalized) IL-4 cytokine response of Group 2a and 2b hip arthroplasty subjects and Group 3 age matched controls. Groups 2a and 2b did not demonstrate statistically significant increases of IL-4 secretion in response to PHA compared to untreated and metal challenged lymphocytes. Likewise, metal challenge did not result in increases in IL-4 secretion.
