Contrary to a similar study performed in Denmark, which found no clinical efficacy of T. suis eggs in MS patients (119), Fleming et al. observed a slight increase in Treg cells, IL-10 and IL-4 in T. suis treated patients, and a reduction of the lesions visible in the MRI scans indicating that administration of T. suis could have potential beneficial effects for patients with MS (118). Here, IL10 is linked to myeloid sarcoma.
