Single-Stranded DNA with Internal Base Modifications Mediates Highly Efficient Knock-In in Primary Cells Using CRISPR-Cas9
[Nucleic Acids Research] Scientists showed that single-stranded DNA (ssDNA) with chemical modifications in 12–19% of internal bases improved knock-in by 2–3-fold compared to end-modified ssDNA in airway basal stem cells, CD34+ hematopoietic cells, T cells, and endothelial cells.
Solid Tumor Immunotherapy Using NKG2D-Based Adaptor CAR T Cells
[Cell Reports Medicine] T cells were engineered to co-express NKG2D with a fusion protein that comprised Dap10 joined to a Dap12 endodomain.
AcrIIIA1 Is a Protein–RNA Anti-CRISPR Complex That Targets Core Cas and Accessory Nucleases
[Nucleic Acids Research] The authors discovered and characterized AcrIIIA1, the first Type III-A specific anti-CRISPR protein. They showed that AcrIIIA1 bound to Csm2 within the Cas10-Csm effector complex and attenuated Cas10’s DNase activity and second messenger production.
AlveoGene Receives Rare Pediatric Disease Designation (RPDD) from FDA for AVG-002, Its Novel, Inhaled Gene Therapy for Lethal Neonatal Surfactant Protein B (SP-B) Deficiency
[AlveoGene] AlveoGene announced that it has been granted a RPDD by the US FDA for AVG-002, its novel inhaled gene therapy for lethal neonatal SP-B deficiency.
Intravenous and Intracranial GD2-CAR T Cells for H3K27M+ Diffuse Midline Gliomas
[Nature] Arm A of Phase I trial no. NCT04196413 administered one intravenous dose of autologous GD2-CART to patients with H3K27M-mutant pontine or spinal DMG at two dose levels following lymphodepleting chemotherapy.
Maturation and Persistence of CAR T Cells Derived from Human Pluripotent Stem Cells via Chemical Inhibition of G9a/GLP
[Cell Stem Cell] Using a stroma-free human iPSC-T cell differentiation platform, researchers screened for epigenetic modulators that influenced T cell specification and identified the H3K9-directed histone methyltransferases G9a/GLP as repressors of T cell fate.
PD-1+CD8+ T Cell-Mediated Hepatocyte Pyroptosis Promotes Progression of Murine Autoimmune Liver Disease
[Advanced Science] Researchers identified a specific expanded pathogenic subset of PD-1+CD8+ T cells in the liver, exhibiting strong functional activity and cytotoxicity against target cells.
Engraftment of a Surrogate Antigen onto Tumor Cell Surface via pHLIP Peptide to Universally Target CAR-T Cell Therapy to Solid Tumors
[Cancer Letters] The authors evaluated the efficiency of Myc-pH-low insertion peptide (pHLIP) in inserting the artificial c-Myc-tag onto the plasma membrane of malignant cells and determined if this engraftment could convert it into a therapeutic target for CAR-T cells or monoclonal antibodies.
Large DNA Deletions Occur During DNA Repair at 20-Fold Lower Frequency for Base Editors and Prime Editors than for Cas9 Nucleases
[Nature Biomedical Engineering] Scientists showed that Cas9-mediated double-strand breaks induced large deletions at varying frequencies in cancer cell lines, human embryonic stem cells, and human primary T cells, and that most deletions were produced by two repair pathways.
Phenotypic Insights into Genetic Risk Factors for Immune-Related Adverse Events in Cancer Immunotherapy
[Cancer Immunology Immunotherapy] Utilizing publicly accessible genome-wide association study data, this investigation evaluated the impact of over 5000 exposure variables on susceptibility to irAEs using univariate Mendelian randomization.
Navigating the Roadblocks: Progress and Challenges in Cell-Based Therapies for Human Immunodeficiency Virus
[Journal of Cellular Biochemistry] The authors address the challenges to cell-based therapies against HIV and discusses the recent advancements aimed at overcoming them.
CAR T Cells and T Cell Therapies for Cancer
[Jama-Journal of The American Medical Association] CAR T-cell therapy is an FDA-approved therapy that has improved progression-free survival for multiple myeloma, improved overall survival for large B-cell lymphoma, and attained high rates of cancer remission for other hematologic malignancies.
