Gene therapy medicinal products (GTMPs) have emerged as a transformative class of medicines. Defining what a certain class of medicines encompasses, and what it does not, is key, with ample implications and consequential regulatory requirements. In April 2023, the European Commission proposed new pharmaceutical legislation safeguarding the public health within the European Union with a new, broader definition of GTMP, including genome editing medicines and nucleic acids of either source, regulating, replacing, or adding a genetic sequence that mediates its effect by transcription or translation.

Article Synopsis
  • Inherited deficiency of alpha-1 antitrypsin (AAT) leads to serious conditions like liver failure and early emphysema, prompting investigations into new therapies.
  • The study explores using pulmonary transplantation of genetically modified macrophages that produce AAT as a potential treatment for lung issues related to AAT deficiency.
  • Experiments show that these modified macrophages successfully integrate into lung tissue, maintain their functionality, and produce human AAT, suggesting a promising approach for future therapies.

Induced pluripotent stem cells (iPSCs) offer great promise for the field of regenerative medicine, and iPSC-derived cells have already been applied in clinical practice. However, potential contamination of effector cells with residual pluripotent cells (e.g.

Induced pluripotent stem cell (iPSC)-derived hematopoietic cells represent a highly attractive source for cell and gene therapy. Given the longevity, plasticity, and self-renewal potential of distinct macrophage subpopulations, iPSC-derived macrophages (iPSC-Mφ) appear of particular interest in this context. We here evaluated the airway residence, plasticity, and therapeutic efficacy of iPSC-Mφ in a murine model of hereditary pulmonary alveolar proteinosis (herPAP).

Recent advances in single-cell transcriptomics techniques have opened the door to the study of gene regulatory networks (GRNs) at the single-cell level. Here, we studied the GRNs controlling the emergence of hematopoietic stem and progenitor cells from mouse embryonic endothelium using a combination of single-cell transcriptome assays. We found that a heptad of transcription factors (Runx1, Gata2, Tal1, Fli1, Lyl1, Erg and Lmo2) is specifically co-expressed in an intermediate population expressing both endothelial and hematopoietic markers.
