Fig 5. Proposed model of M2-skewing of SHIP+/+ and -/- MФs.

Fig 5

SHIP-/-, but not +/+, basophils constitutively secrete sufficient IL-4 to M2 skew SHIP+/+ or -/- progenitors or mature MФs but only in the presence of ATRA, TGFβ and PGE2 in MP. These MP factors synergize with low levels of IL-4 to M2 skew the MФs under non-inflamed conditions.
