Illustration of a cell infection by an IRES (Internal Ribosomal Entry Site) virus, and the its treatment. The Hepatitis C virus is an RNA virus, carrying an IRES sequence. In the case of infection (top), the IRES sequence (red) of the viral RNA (yellow) enables it to latch onto the small cellular ribosome unit that contains RACK1 protein (blue square). The ribosome will synthesize the viral proteins instead of the cellular proteins. The virus replicates itself and infection spreads through the body. During treatment (at the bottom), the RACK1 protein is eliminated and the ribosome carries on translating the cellular RNA. The viral RNA can no longer use it to synthesize its own proteins; the virus cannot spread.

Recruitment of immune cells, innate immunity. This illustration shows the phenomenon of diapedesis. This phenomenon corresponds to the passage of immune cells into tissues from the bloodstream. It takes place in several phases. The first phase is the capture phase. The immune cell in the blood vessel comes close to the endothelial cells (endothelium of the blood vessel). The second phase is the adhesion and rolling phase. It activates immune cells. It expresses in an increased manner the adhesion molecules expressed by the immune cells and those presented on the surface of the endothelium. Then the third phase is the adhesion phase. The cell adheres strongly to the endothelium thanks to the numerous adhesion molecules. Finally, the fourth phase is the migration phase. The recruited cell crosses the endothelium to the site of inflammation. Then the immune cell will activate and produce cytokines. Therefore the production of cytokines maintains or amplifies the inflammatory response at t

Artist's concept showing carbon balls coming out from the type of object where they were discovered, a dying star and the material it sheds, known as a planetary nebula. The official name of these carbon balls is a buckminsterfullerene, and often referred to as buckyballs. Buckyballs are made up of 60 carbon atoms organized into spherical structures that resemble soccer balls. The Spitzer Space Telescope was able to find convincing signs of buckyballs using its sensitive infrared vision. Th

The National Institutes of Health awarded $17 million in 2013 for 24 research projects designed to improve scientists' understanding of a recently discovered type of cell-to-cell communication based on extracellular (outside the cell) RNA, also called exRNA. Through these awards, scientists explore the basic biology of exRNAs and develop tools and technologies that apply new knowledge about exRNAs to disease research, diagnosis and treatment. exRNAs travel in body fluids, including fluids surrounding the brain and spinal cord, urine, and blood.
