Scientists may have found a permanent cure for autoimmune diseases

For decades, autoimmune diseases like lupus, multiple sclerosis, and type 1 diabetes have been managed, but not completely cured. Now, however, a revolutionary change is taking place, as doctors are using a therapy called CAR T-cell, originally known as an advanced cancer treatment, to target and destroy the problematic immune system cells that cause these diseases.
Unlike traditional treatments that simply weaken the immune system, this method reprograms the patient's own T cells to find and eliminate only the cells that cause damage in the body. Early clinical trials have yielded results that researchers describe as "miraculous," with patients making full recovery from diseases that were previously considered permanent or life-threatening.
Surprisingly, severe side effects that often occur in cancer patients, such as brain inflammation, have hardly been observed in cases of autoimmune disease treatment.
Researchers believe this is because the body's intact immune system is able to eliminate the modified cells after they have completed their task, in a way restarting the body's natural defenses. Although the high cost of personalized treatments remains a barrier, the development of "off-the-shelf" versions and therapies that are applied directly to the body is expected to make these methods more affordable and accessible.
