About five years ago, Professor Janet Sawicki at the Lankenau Institute in Pennsylvania read an article about nanoparticles developed by MIT’s Daniel Anderson and Robert Langer for gene therapy, the insertion of genes into living cells for the treatment of disease. Sawicki was working on treating ovarian cancer by delivering — through viruses — the gene for the diphtheria toxin, which kills tumor cells (…)

Blood vessel blockage, a common condition in old age or diabetes, leads to low blood flow and results in low oxygen, which can kill cells and tissues. Such blockages can require amputation resulting in loss of limbs. Now, using mice as their model, researchers at Johns Hopkins have developed therapies that increase blood flow, improve movement and decrease tissue death and the need for amputation. The findings, published online last week in the early edition of the Proceedings of the National Academy of Sciences, hold promise for developing clinical therapies.

It was stunning to see them closed inside of those plastic bubbles, kept far from all external contact because their immune system does not react against any foreign antigens. Today scientists can say that ADA-SCID (adenosine deaminase deficiency), a serious combined immunodeficiency caused due to a lack of the adenosine deaminase enzyme, has been definitively defeated by gene therapy developed at San Raffaele of Milan.
The final study, which combined the conclusions of clinical studies, which began in 2000 on strategic therapies developed by the HSR-TIGET (San Raffaele Telethon Institute for Gene Therapy) group, led

Scientists are one step closer to creating a gene therapy/stem cell combination to combat genetic diseases. With work, this research may lead to not only curing the disease, but also repairing the damage left behind.
While gene therapy is a burgeoning field that has shown great results in treating genetic disorders, many of those diseases leave behind heavily damaged tissue that the body is unable to repair. So even if the disease is completely eradicated, quality of life may not necessarily improve, and without help, health can still continue to deteriorate.
Since stem cell research began, there

It has been about 8 years since Salsabil, the first Palestinia baby suffering congenital immunodeficiency (Ada-Scid), has been healed using gene therapy. And it has been about 7 years since her story to Abdul Rahim’s one, a Pakistani baby born in the end of 2006 in Qatar.
His parents did lose 3 children because of Ada-Scid, and Abdul’s case is one of the most symbolic.
Just after his birth doctors did diagnose his illness and succeeded to healt his pneumonia during his first days of life.
So Abdul’s parents and doctors who were follow him contacted the San Raffaele Telethon
