The analysis using Ro/e and MiloR algorithms revealed a higher proportion of CTLA4_CD4_Treg, CXCL13_CD4_Tex and STMN1_CD4_Tpro cells in the Fibrosis+ LM, whereas ANXA1_CD4_Tm and FOS_CD4_Tm cells were more prevalent in the Fibrosis− LM (Fig. 2b–d). The gene discussed is CD4; the disease is fibrosis.
