The result showed that the percentages of LRG1+ cells present in CD15+ and CD3-CD56+ cell populations were higher in patients with LN when compared with HC subjects (P = 0.0004 and P = 0.04, respectively), but not in CD14+ (P = 0.09), CD3+ (P = 0.079) and CD19+ (P = 0.098) cell populations. This evidence concerns the gene CD19 and lobular neoplasia.
