Gene therapy may be classified into two types by the type of cell it affects: somatic cell and germline gene therapy. In somatic cell gene therapy (SCGT), the therapeutic genes are transferred into any cell other than a gamete , germ cell , gametocyte , or undifferentiated stem cell .
The therapy known as Casgevy [11] works through editing a dysfunctional protein that interferes with creation of adult hemoglobin. This gene is known as the BCL11A, and when people have Beta thalassemia, their bodies do not make enough adult hemoglobin. Casgevy uses precise gene editing of stem cells, and reduces the activity of BCL11A.

A number of recent clinical trials have suggested that gene therapy could help treat diseases of the eye that cause vision loss. This Special Feature explores the current evidence and outstanding ...
Although not enough time has passed to declare the patients "cured" of their sickle cell disease, after gene therapy, 95% of recipients, like Stephenson, are symptom-free. "It's been one ...
Viruses that have been used for gene therapy are, adenovirus, lentivirus, retrovirus and the herpes simplex virus. [10] The most common virus used for gene delivery come from adenoviruses as they can carry up to 7.5 kb of foreign DNA and infect a relatively broad range of host cells, although they have been known to elicit immune responses in ...
Student Zoe Davis, 20, was just weeks into her junior year when she landed back in the hospital with severe sickle cell pain earlier this month. She knows new gene therapies may provide long-term ...
Gene therapy seeks to modulate or otherwise affect gene expression via the introduction of a therapeutic transgene. Gene therapy by viral vectors can be performed by in vivo delivery by directly administering the vector to the patient, or ex vivo by extracting cells from the patient, transducing them, and then reintroducing the modified cells ...
