‘Superman’ B-cells bash MS in mice
“It’s easy to collect B-cells from a patient. It’s just like donating blood. We purify them in the lab, treat them with GIFT15 in a petri dish, and give them back to the patient,” says study leader Jacques Galipeau. “That’s what we did in mice, and that’s what we believe we could do in people. It would be very easy to take the next step; it’s just a question of finding the financial resources and partnerships to make this a reality.” (Credit: Claudio Calligaris/McGill University)
