Fig. 6From: Immunomodulatory role for membrane vesicles released by THP-1 macrophages and respiratory pathogens during macrophage infectionEffect of polymyxin B treatment on the TNF-α release in response to MVs released during infection or bacterial culture. THP-1 macrophages were pre-incubated for 1 h with polymyxin B prior to overnight stimulation with MVs released upon infection (MVs: a) or bacterial culture (bMVs: b). Data are represented as the mean ± SEM (n = 3). ***p < 0.001Back to article page
