Transmission electron micrograph of orf viruse, computer-coloured mauve. Orf is a parapoxvirus which mainly affect sheep and goats but can be transmitted to humans who work closely with these animals. It usually manifests as a single lesion on the hands or arms and is also known as contagious pustular dermatitis virus.

This image shows a scanning electron micrograph of the surface of a HeLa cell that has been treated with a drug to induce exosome (here seen as small particles) release. Exosomes are a type of vesicle, or fluid-filled space surrounded by a membrane, that are released from cells. Our understanding of how they behave is in its infancy, but exosomes have already been implicated in numerous disease states, including neurodegenerative diseases and cancer.


Here, it is shown for the first time that exosomes remain associated to the surface of cells following their expulsion from the cell. The image helps to demonstrate that exosomes are retained in small clusters, and further work has shown that these clusters are held together by the protein 'tetherin' which plays a similar role in holding viruses to the surface of cells as a means of limiting viral spread.

Transmission electron micrograph of orf virus, compuer coloured blue on white. Orf is a parapoxvirus which mainly affect sheep and goats but can be transmitted to humans who work closely with these animals. It usually manifests as a single lesion on the hands or arms and is also known as contagious pustular dermatitis virus.

Transmission electron micrograph of adenovirus, computer-coloured mauve. These DNA viruses cause infections of the upper respiratory tract similar to the common cold. The virus particles are 70-90 nanometres in diameter.

Transmission electron micrograph of 4 specimens of Herpes simplex virus, compuer-coloured blue.These viruses cause inflammation of the skin or mucus membranes, typically causing clusters of small blisters.
