SLPs differentially modulate cell surface marker expression on macrophages. J774 macrophages were stimulated with SLP from ribotypes 001, 014, 027 and 078 (20 μg/mL) for 24 h. LPS (100 ng/mL) was used as a positive control. Results show expression of the cell surface markers CD80 and CD86. Control cells are shaded in grey, SLP-stimulated cells are labelled in blue, and LPS-stimulated cells are labelled in red
