In the case of AILD this could include Treg expression of CXCR3 to facilitate recruitment to inflamed autoimmune livers, CCR6 and CXCR3 to position Treg around inflamed hepatocytes and biliary epithelium and CCR4 for close localisation of Treg around DC to enhance Treg suppressive function, survival and proliferation. Here, CXCR3 is linked to angioimmunoblastic T-cell lymphoma.
