IL10 and myeloid sarcoma: In support, TCR-specific Th2 cells inhibit the MBP-specific Th1 response in vitro through the release of IL-10, and a triplicate TCR vaccine (BV5S2, BV6S5, and BV13S1 peptides) increases the numbers of circulating IL-10-secreting T cells, reactive to the TCR peptides, in MS patients [67].
