Interestingly, the CD11c+ B cells from 2 out of 3 MuSK-MG subjects produced high levels of anti-MuSK antibodies in response to CD40L and cytokines, whereas CD11c+ B cells from AChR did not produce levels of AChR antibodies that were different from controls (Figure 8D). This evidence concerns the gene ITGAX and myasthenia gravis.
