Researchers Get under the Skin to Develop New Transplant Technique
Researchers describe developing a new site for islet transplantation under the skin, which they believe will offer less risk and far greater health benefits for patients. Islet transplantation is a procedure that temporarily allows people with severe diabetes to stop taking insulin.

Mutant MHC Class II Epitopes Drive Therapeutic Immune Responses to Cancer
Recently, the authors proposed a personalized immunotherapy approach to target the full spectrum of a patient’s individual tumor-specific mutations. They showed in three independent murine tumor models that a considerable fraction of non-synonymous cancer mutations is immunogenic and that, unexpectedly, the majority of the immunogenic mutanome is recognized by CD4+ T cells.

Selective Elimination of Mitochondrial Mutations in the Germline by Genome Editing
Researchers report on a strategy toward preventing germline transmission of mitochondrial diseases by inducing mtDNA heteroplasmy shift through the selective elimination of mutated mtDNA. As a proof of concept, investigators took advantage of NZB/BALB heteroplasmic mice, which contain two mtDNA haplotypes, BALB and NZB, and selectively prevented their germline transmission using either mitochondria-targeted restriction endonucleases or TALENs.

Outcomes following Gene Therapy in Patients with Severe Wiskott-Aldrich Syndrome
Investigators assessed the outcomes and safety of autologous hematopoietic stem cell (HSC) gene therapy in Wiskott-Aldrich syndrome. Gene-corrected autologous HSCs were infused in seven consecutive patients with severe Wiskott-Aldrich syndrome lacking HLA antigen-matched related or unrelated HSC donors following myeloablative conditioning.

Monoclonal Antibodies against GARP/TGF-β1 Complexes Inhibit the Immunosuppressive Activity of Human Regulatory T Cells In Vivo
Two anti-GARP monoclonal antibodies were generated that block the production of active transforming growth factor–β1 (TGF-β1) by human regulatory T cells (Tregs). In a model of xenogeneic graft-versus-host disease in NSG mice, the blocking antibodies inhibited the immunosuppressive activity of human Tregs. [Sci Transl Med] Abstract

CNTF Gene Therapy Confers Lifelong Neuroprotection in a Mouse Model of Human Retinitis Pigmentosa
The long-term outcome of neuroprotection as a therapeutic strategy for preventing cell death in neurodegenerative disorders remains unknown, primarily due to slow disease progression and the inherent difficulty of assessing neuronal survival in vivo. Employing a murine model of retinal disease, scientists demonstrated that ciliary neurotrophic factor (CNTF) confers life-long protection against photoreceptor degeneration. [Mol Ther]
Abstract
Lentivector Knock-Down of CCR5 in Hematopoietic Stem Cells Confers Functional and Persistent HIV-1 Resistance in Humanized Mice
Investigators combined CCR5 knock-down by a highly efficient miRNA lentivector with pre-transplantation selection of transduced hematopoietic stem and progenitor cells to obtain a rather pure population of gene engineered CD34+ cells. [J Virol] Abstract
Placental Mesenchymal Stromal Cells Rescue Ambulation in Ovine Myelomeningocele
Scientists demonstrated that using early gestation human placenta-derived mesenchymal stromal cells to augment in utero repair of myelomeningocele (MMC) resulted in significant and consistent improvement in neurologic function at birth in the rigorous fetal ovine model of MMC.

CRISPR/Cas9-Mediated Gene Editing in Human Tripronuclear Zygotes
Investigators used tripronuclear zygotes to further investigate clustered regularly interspaced short palindromic repeat-associated system (CRSIPR/Cas9)-mediated gene editing in human cells. They found that CRISPR/Cas9 could effectively cleave the endogenous β-globin gene. [Protein Cell] Full Article

High-Scoring Grant Applications Yield More Highly Cited Papers
Grant applications that are ranked more highly by peer reviewers go on to yield more patents and highly cited papers, an analysis of more than 130,000 funded grants finds. The study contradicts the widely held belief — supported by some previous findings — that there is scant connection between reviewers’ scores of a research proposal and its subsequent impact.
