TOP STORY

Immunotherapy Achieves Breakthrough Result in Patients with Hodgkin Lymphoma
A therapy that liberates the immune system to attack cancer cells drove Hodgkin lymphoma into complete or partial remission in fully 87 percent of patients with resistant forms of the disease who participated in an early-phase clinical trial. The results provide some of the most dramatic evidence to date of the potential of therapies that increase the ability of the immune system to kill cancer cells.

Towards a Therapy for Angelman Syndrome by Targeting a Long Non-Coding RNA
Scientists developed a potential therapeutic intervention for Angelman syndrome by reducing UBE3A antisense transcript Ube3a-ATS with antisense oligonucleotides (ASOs). ASO treatment achieved specific reduction of Ube3a-ATS and sustained unsilencing of paternal Ube3a in neurons in vitro and in vivo. [Nature]

Multivalent N-Acetylgalactosamine-Conjugated siRNA Localizes in Hepatocytes and Elicits Robust RNAi-Mediated Gene Silencing
Conjugation of small interfering RNA (siRNA) to an asialoglycoprotein receptor ligand derived from N-acetylgalactosamine facilitates targeted delivery of the siRNA to hepatocytes in vitro and in vivo. [J Am Chem Soc] Abstract | Graphical Abstract

Tolerance Induction to Human Stem Cell Transplants with Extension to Their Differentiated Progeny
Scientists show that brief induction with monoclonal antibody-mediated coreceptor and costimulation blockade enables long-term engraftment and tolerance towards murine ESCs, hESCs, human induced pluripotent stem cells and hESC-derived progenitors in outbred murine recipients. [Nat Commun] Abstract | Press Release

Mybpc3 Gene Therapy for Neonatal Cardiomyopathy Enables Long-Term Disease Prevention in Mice
Scientists show successful long-term cardiac myosin-binding protein C 3 (Mybpc3) gene therapy in homozygous Mybpc3-targeted knock-in mice, which genetically mimic these human neonatal cardiomyopathies. [Nat Commun] Abstract

Anti-CD33 Chimeric Antigen Receptor Targeting of Acute Myeloid Leukemia
Scientists generated a second generation CD33-specific chimeric antigen receptor capable of redirecting cytolytic effector T cells against leukemic cells. Chimeric antigen receptor-modified T cells efficiently killed leukemia cell lines and primary tumor cells in vitro. [Haematologica] Abstract | Full Article

Ex Vivo-Expanded but Not In Vitro-Induced Human Regulatory T Cells Are Candidates for Cell Therapy in Autoimmune Diseases Thanks to Stable Demethylation of the Foxp3 Regulatory T Cell-Specific Demethylated Region
Researchers undertook a systematic comparison of expanded regulatory T cells (Tregs) and induced Tregs to recommend the most suitable for clinical implementation, and then tested their effectiveness and feasibility in rheumatoid arthritis. [J Immunol] Abstract

Chemokine-Mediated Robust Augmentation of Liver Engraftment: A Novel Approach
For in vivo studies, investigators used a nude mouse model of partial hepatectomy followed by intraparenchymal injections of chemokine ligands at various concentrations. [Stem Cells Transl Med] Abstract

Tissue Engineering of Rat Bladder Using Marrow-Derived Mesenchymal Stem Cells and Bladder Acellular Matrix
When mesenchymal stem cells (MSCs) were seeded on acellular matrix scaffold, they remained viable and proliferative while adopting a cellular phenotype consistent with their microenvironment. Upon transplantation in rats after partial cystectomy, MSC-seeded bladder acellular matrix (BAM) proved superior to unseeded BAM with animals recovering nearly 100% normal bladder capacity for up to six months.

Benefits Persist in T Cell Therapy for Children with Relapsed Leukemia
An innovative cell therapy against a highly aggressive form of acute lymphoblastic leukemia continues to show highly promising results in children treated in a pilot study. Ninety-two percent of the 39 children receiving bioengineered T cells had no evidence of cancer at one month after treatment, with this complete response persisting in some cases for more than two years.
