Figure 2: Mice offspring with lipopolysaccharide or polyinosinic:polycytidylic acid prenatal infection develop more Munro microabscesses after 5-day imiquimod application. (a) Showed the density of Munro microabscesses, which was calculated as the number of Munro microabscess divided by the length of epidermis (millimeter). Protein expression level of Ly6G was examined by western blotting. (b) Showed that both lipopolysaccharide and polyinosinic:polycytidylic acid groups had more Ly6G expression than phosphate-buffered saline controls. LPS: Lipopolysaccharide, Poly I:C: Polyinosinic:polycytidylic acid, PBS: Phosphate-buffered saline, IMQ: Imiquimod. *: P < 0.05, **: P < 0.01, ****: P < 0.0001, ns: Not significant.
