LXRα, LXRβ, and RXRα expression in human DCs. (A) mRNA expression of LXRα was analyzed in human peripheral blood CD14⁺ monocytes (set to 100%), myeloid DCs (myDCs) directly after isolation and after 2 days in culture (2d-myDCs), as well as of monocyte-derived immature DCs (iDCs) and mature DCs (mDCs) by QRT-PCR. (B) LXRα and LXRβ induction during DC differentiation. LXRα and LXRβ mRNA expression were analyzed at different time points during DC differentiation from monocytes (d0 set to 100%). Data show means and SEM of 4 independent experiments.
