PnIIs express MHC class II molecules at their surface and at the limiting membrane of lamellar bodies. A: Double-immunogold labeling of an isolated mouse lung cell ultrathin cryosection showed the presence of MHC class II on the basolateral plasma membrane (PM) and in lamellar bodies (LB) together with SP-B. B: Double-immunogold staining for MHC class II (10 nm) and DC-LAMP (15 nm) demonstrated co-localization of both proteins at the LB limiting membrane. Original magnifications, ×35,000. Scale bars, 200 nm.
