On depletion of combined nitrogen, the filamentous cyanobacterium Anabaena sp. PCC 7120 forms N2-fixing heterocysts from vegetative cells. To protect the oxygen-sensitive nitrogenase, a heterocyst-specific layer composed ...
Antiviral cytotoxicity of lymphocytes such as natural killer (NK) cells, CD8 alpha-beta T cells and gamma-delta T cells is stimulated by the activating immunoreceptor NKG2D, which has the remarkable ability to engage at ...
Protein synthesis is one of the costliest processes in the cell. Therefore, the initiation of translation is a tightly regulated process. One major control mechanism targets the activity or formation of the so-called eIF4F ...
The attachment of viruses to host cells and subsequent viral entry are key steps in viral infection. Receptor recognition also serves an essential function in target cell selection. Mammalian orthoreoviruses (reoviruses) ...
Messenger RNA (mRNA) is the working copy of a gene containing the information for the production of a specific protein. The amount of any given protein has to be adjusted to the current needs of a cell. One mechanism for ...
Polyoma- and adenoviruses are important human pathogens with worldwide significance. Both are non-enveloped DNA viruses, but differ significantly in terms of how they infect humans: Polyomaviruses (PyVs) cause persistent ...
The Mesoproterozoic Mount Painter Inlier in the northern Adelaide Fold and Thrust Belt in South Australia comprises an exceptionally large area of massive metasomatic/hydrothermal K-feldspar-quartz-rich rocks and diverse ...
