CRP and eosinophilic esophagitis: The glycoprotein Lipocalin-2 (also known as neutrophil gelatinase-associated lipocalin), the matricellular protein NOV3 (also known as cellular communication factor 3), and the marker of inflammation CRP have yet to be linked to EoE, although they have each been associated with fibrosis with NOV3 specifically identified as an inhibitor of fibrosis in the kidney (49–52).
