Sickle Cell Disease Hematopoietic Stem Cell gene therapy with globin gene addition is promising

Autologous transplantation of gene-modified HSCs might be used to treat Sickle Cell Disease (SCD) once and for all. Hematopoietic Stem Cell (HSC) gene therapy with lentiviral-globin gene addition was optimized by HSC collection, vector constructs, lentiviral transduction, and conditioning in the current gene therapy experiment for SCD, resulting in higher gene marking and phenotypic correction. Further advancements over the next decade should allow for a widely approved gene-addition therapy. Long-term engraftment is crucial for gene-corrected CD34+ HSCs, which might be addressed in the coming years, and gene repair of the SCD mutation in the-globin gene can be achieved in vitro using genome editing in CD34+ cells. Because of breakthroughs in efficacy, safety, and delivery strategies, in vivo gene addition and gene correction in BM HSCs is advancing. Overall, further research is needed, but HSC-targeted gene addition/gene editing therapy is a promising SCD therapy with curative potential that might be widely available soon.
