Chaz, Great answer by Ohm20 about multiple sclerosis. The time he has spent learning all the science is so valuable to board readers like me. As a long long, I only remember from investor update calls that we have had great (amazing per NP) pre-clinical MS mouse data for a long time. With lots of people affected by MS and others dying quickly and painfully from GvHD, the slow roll of trials limited by funding has been frustrating for a long time. GLTA.
