Evaluation of the Inflammatory Response in Macrophages Stimulated with Exosomes Secreted by Mycobacterium avium-Infected Macrophages

Figure 1

Exosomes as observed by transmission electron microscopy (TEM) and analyzed by SDS-PAGE. (a) Exosomes secreted from untreated macrophages, as viewed by TEM (70,000x magnification, scale bar: 100 nm). (b) Exosomes secreted from macrophages infected with M. avium viewed by TEM as per (a). (c) (−)Exosomes and (+)exosomes were analyzed by 10% SDS-PAGE. Arrows indicate variation in the concentration of specific molecular weight proteins.
