IL10 and myeloid sarcoma: Likewise, B cells from paracoccidioides brasiliensis-infected patients, although expressing Th2 immune responses after antigen-stimulation of peripheral blood mononuclear cells (PBMC), exhibited B-cell IL-10 production levels similar to those observed in uninfected MS patients, suggesting that increased production of IL-10 by B cells found in helminth-infected MS patients is not determined by the Th2 profile present in these individuals.
