Regulation of TSH-βv by LPS, LPS/IFN-γ (IFNG), and IL-4/IL-10. Differentiated THP-1 macrophage cultures were treated with LPS, LPS/IFNγ, and IL-4/IL-10 for 24 hours and gene expression examined for TSH-βv (A), MCSF (B), CCL-2 (C), Wnt5A (D), MARC1 (E), and Wnt10-A (F). These data revealed that both M1 stimulation with LPS/IFNγ and M2 stimulation with IL-4/IL-10 induced TSHβv gene expression by up to 30-fold (A). *, P < .05; **, P < .001. cont, control.
