Moreover, in this fibrocyte population, the percentage of HLA-DR+ cells was very low (22.1 ± 21.1% and 13.1 ± 4.7%, respectively), whereas the percentage of CD86+ cells was higher in both SSc patients and HSs at T0 (34.4 ± 21.4% and 68.9 ± 27.6%) (Fig. 1a). The gene discussed is CD86; the disease is systemic sclerosis.
