miR-29b negatively regulates human osteoclastic cell differentiation and function: Implications for the treatment of multiple myeloma-related bone di…

2013

Skeletal homeostasis relies upon a fine tuning of osteoclast (OCLs)-mediated bone resorption and osteoblast (OBLs)-dependent bone formation. This balance is unsettled by multiple myeloma (MM) cells, which impair OBL function and stimulate OCLs to generate lytic lesions. Emerging experimental evidence is disclosing a key regulatory role of microRNAs (miRNAs) in the regulation of bone homeostasis suggesting the miRNA network as potential novel target for the treatment of MM-related bone disease. Here, we report that miR-29b expression decreases progressively during human OCL differentiation in vitro. We found that lentiviral transduction of miR-29b into OCLs, even in the presence of MM cells,…

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…

COVID-19 Vaccination Willingness and Hesitancy in Patients With Inflammatory Bowel Diseases: Analysis of Determinants in a National Survey of the Ita…

2021

The coronavirus disease 2019 (COVID-19) pandemic has not finished yet, and the most promising option towards its ending is widespread vaccination. Because patients with inflammatory bowel diseases (IBDs), namely Crohn’s disease (CD) and ulcerative colitis (UC), often require immune-modifying treatment, which might increase the risk of opportunistic infection,1 their vaccination history for several infectious diseases is routinely checked, and when inadequate, vaccination is performed at diagnosis or ideally before immune suppressive treatment is started.1 However, IBD patients were not found to be at an increased risk of developing COVID-19 or of experiencing a more severe disease course.2

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…

P463 COVID-19 vaccination willingness and hesitancy in patients with Inflammatory Bowel Diseases (IBD): analysis of determinants in a national survey…

2021

Abstract Background Vaccine hesitancy, the delay in acceptance or refusal of vaccination despite its availability, represents a threat to the diffusion and lethality of infectious diseases. COVID-19 vaccination has been recommended by national and international organizations in patients with Inflammatory Bowel Diseases (IBD). The aim of the study was to evaluate COVID-19 vaccine willingness and hesitancy in a population of Italian patients with IBD, and their determinants. Methods In February 2021 an online questionnaire focused on COVID-19 vaccine was proposed to a representative sample of Italian IBD patients. Socio-demographic characteristics, IBD features, lifestyle, perception of COVID…
