Studies discovered that CXCL10 was expressed in borderline tuberculoid (BT), mid-borderline (BB), borderline lepromatous (BL), and lepromatous (LL) leprosy skin lesions with varying levels and also increased in paucibacillary (PB) leprosy patients’s plasma (Ferreira et al., 2021; Sharma et al., 2015). Here, CXCL10 is linked to leprosy.
