CXCR3 and ganglioneuroma: Segerer et al. [35] studied CXCR3-positive cells in renal biopsies from patients with GN by immunohistochemistry and found that CXCR3-positive cells were relatively rare in glomerular tufts, as there was no evidence of CXCR3 on mesangial cells, and the main site of CXCR3 expression was infiltrating T cells in the tubulointerstitium.
