IL4 and myeloid sarcoma: 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).
