Under The Microscope


This is a blog dedicated to sharing and compiling many different images from under the microscope. From living to non-living, we can appreciate the invention of the microscope that has allowed us to see the into world of the very small.

Cryo-SEM image of a rapid frozen parasite-host interaction. Here Shigella bacteria (in red) attacking a He-La cell, which in a defence reaction forms F-actin induced wide membrane ruffles on its surface (bright blue). The bacterium interacts with the host cell membrane by injecting its invasins, which act to choreograph a local actin-rich membrane ruffle at the host cell surface (Niebuhr and Sansonetti, 2000). The ruffle engulfs the bacterium and eventually disassembles, internalising the bacterium.
