We thus next investigated this possibility in a small cohort of samples from healthy controls or individuals with either multiple sclerosis (MS) or Spondylarthritis (SpA) using M0 (unstimulated), M1 (LPS/IFNγ) or M2 (IL-4/IL-10/TGF-β) polarization protocols. Here, TGFB1 is linked to myeloid sarcoma.
