IL10 and sarcoidosis: Within most Th1-dominant mycobacterial granuloma models, unchanged secretion levels of IL-10 [22,23,41,51,56,57] were observed while significantly elevated secretion of IL-10 was observed across studies using Schistosoma [32,35,58] or Candida antigens [42] or in studies focusing on sarcoidosis [54,59].
