In parallel, the release of the pro‐inflammatory cytokines IL‐6, LIF (member of the IL‐6 family), IL‐7 and IL‐8, as well as leptin, HGF, IGFBP1, FLT3 ligand (FLT3L), BDNF and PDGFBB, was reduced in BL001‐treated T1D iDC (Figure 1J,K). This evidence concerns the gene LEP and type 1 diabetes mellitus.
