PGLYRP1 is highly expressed predominantly in neutrophils’ and eosinophils’ granules and its expression was associated with various inflammatory conditions [62,65,66,67], including atherosclerotic disease [68,69,70], acute myocardial infarction [71], rheumatoid arthritis [72], asthma [73], oral inflammation [74,75,76], and cancer [77]. This evidence concerns the gene PGLYRP1 and rheumatoid arthritis.
