Massone (2011) [33] studied FOXP3+ in patients coinfected with HIV-leprosy in a reduced sample of 14 patients, with five individuals in RR and four in IRIS, and observed that FOXP3+ cells were detected in all clinical forms of leprosy in an average of 3%–4% of cells per lymphocytic infiltrate, similar to results in cases of HIV-negative leprosy seen previously by the same author. Here, FOXP3 is linked to leprosy.
