miR-21 antagonism abrogates Th17 tumor promoting functions in multiple myeloma
2020
Multiple myeloma (MM) is tightly dependent on inflammatory bone marrow microenvironment. IL-17 producing CD4+ T cells (Th17) sustain MM cells growth and osteoclasts-dependent bone damage. In turn, Th17 differentiation relies on inflammatory stimuli. Here, we investigated the role of miR-21 in Th17-mediated MM tumor growth and bone disease. We found that early inhibition of miR-21 in naive T cells (miR-21i-T cells) impaired Th17 differentiation in vitro and abrogated Th17-mediated MM cell proliferation and osteoclasts activity. We validated these findings in NOD/SCID-g-NULL mice, intratibially injected with miR-21i-T cells and MM cells. A Pairwise RNAseq and proteome/phosphoproteome analysis…
Therapeutic afucosylated monoclonal antibody and bispecific T-cell engagers for T-cell acute lymphoblastic leukemia
2021
BackgroundT-cell acute lymphoblastic leukemia (T-ALL) is an aggressive disease with a poor cure rate for relapsed/resistant patients. Due to the lack of T-cell restricted targetable antigens, effective immune-therapeutics are not presently available and the treatment of chemo-refractory T-ALL is still an unmet clinical need. To develop novel immune-therapy for T-ALL, we generated an afucosylated monoclonal antibody (mAb) (ahuUMG1) and two different bispecific T-cell engagers (BTCEs) against UMG1, a unique CD43-epitope highly and selectively expressed by T-ALL cells from pediatric and adult patients.MethodsUMG1 expression was assessed by immunohistochemistry (IHC) on a wide panel of normal t…
