<p>CD4<sup>+</sup> T cells, CD16<sup>−</sup> monocytes and CD16<sup>+</sup> monocytes from patients with SLE and healthy donors immunised with the yellow fever vaccine (designated as “Viral infection”) were analysed using the Ingenuity Pathway Analysis (IPA) tool. (A) Commonly observed pathways in all compared groups. (B) Dominantly observed pathways in the CD4<sup>+</sup> T cells from the SLE patients. (C) Dominantly observed pathways in the CD16<sup>−</sup> monocytes from the SLE patients. (D) Dominantly observed pathways in the CD16<sup>+</sup> monocytes from the SLE patients.</p
