A proof of concept of ex vivo genetic modification of cells from patients and their transplantation in mice has demonstrated, for the first time, the therapeutic possibilities of prime editing in sickle cell disease (SCD).
Base editing (BE), a technique that modifies a single nucleotide in living cells, has been successfully tested to resolve the CD3δ mutation in severe combined immunodeficiencies (SCIDs) and produce functional T cells. For now, scientists at the University of California, Los Angeles (UCLA), completed the study on patient stem cells and artificial thymic organoids, shortening the way for future clinical trials.
Estrella Biopharma Inc. has received FDA clearance of its IND application for lead product candidate EB-103, a T-cell therapy targeting CD19, a protein expressed on the surface of almost all B-cell leukemias and lymphomas.
Thymmune Therapeutics Inc. has secured US$7 million in seed financing to support its work in developing scalable thymic cell therapies to restore immune function in aging and disease.
Unexpected behavior of neutrophils unveiled by researchers at Stanford University could lead to a new type of immunotherapy to treat cancer. Although various studies have suggested that these cells are harmful due to their immunosuppressive characteristics, the scientists saw in them an opportunity to redirect them and eliminate tumors.
The efficacy of allogeneic cell therapeutics for regenerative or oncology indications can be compromised by the emergence of antibodies against those cells, as observed in clinical trials. To overcome this limitation, scientists from the University of California and collaborators have developed a gene engineering approach providing antibody protection for cell therapeutics. The new approach to protecting cells from antibody-mediated cellular cytotoxicity (ADCC) relies on the overexpression of the IgG receptor CD64.
Researchers at the Barcelona Institute of Science and Technology’s Center for Genomic Regulation (CRG) and Pulmobiotics Ltd. have used one bacterium to fight another. In mouse models, the team used engineered Mycoplasma pneumoniae to treat Pseudomonas aeruginosa, the chief culprit in ventilator-associated pneumonia (VAP).
A combination of bioengineering techniques on normal cell binding proteins could be the method of the future for selective cell binding. Scientists at the University of California, San Francisco (UCSF) have created a synthetic glue based on the expression of membrane receptors to establish the desired connection between cells. The results may be applied in different fields of cell biology or biomedicine, such as regeneration and wound repair, including the nervous system, or cancer.
