One woman and two men with severe autoimmune conditions have gone into remission after being treated with bioengineered and CRISPR-modified immune cells1. The three individuals from China are the first people with autoimmune disorders to be treated with engineered immune cells created from donor cells, rather than ones collected from their own bodies. This advance is the first step towards mass production of such therapies.
One of the recipients, Mr Gong, a 57-year-old man from Shanghai, has systemic sclerosis, which affects connective tissue and can result in skin stiffening and organ damage. He says that three days after receiving the therapy, he felt his skin loosen and he could start moving his fingers and opening his mouth again. Two weeks later, he returned to his office job. “I feel very good,” he says, more than a year after receiving the treatment.
