Fig. 1From: Immunomodulatory role for membrane vesicles released by THP-1 macrophages and respiratory pathogens during macrophage infectionCryo-EM analysis of MVs released by THP-1 macrophages (a) or during bacterial culture of NTHi (b), Mrc (c), Spn (d), and Psa (e). MVs released during bacterial culture show a similar size and appearance. The median is based on the diameter as obtained by cryo-EM imaging (f). Scale bar represents 200Â nmBack to article page
