 | | |  In response to environmental changes and nutrient starvation, cells are known to undergo extreme alterations. This includes switching from one type to another (“differentiation”) and changes in metabolic pathways (“metabolic switching”). | | | | |  The study of cell-nanoparticle interactions is vital for researchers specializing in the fields of nanomedicine and nanotoxicology. In nanotoxicology, the quantity of nanoparticles internalized by the cells or attached to the external surfaces of cells, regulate the toxic profile of those particles. | | | | |  The protein, called syndecan-4, combines with fellow cell membrane proteins, called integrins, to form protruding 'hands' that sense the environment outside the cell. | | | | |  All living organisms respond and adapt to changes in their environment. These responses are sometimes so significant that they cause alterations in the internal metabolic cycles of the organism--a process called "metabolic switching." For example, rice blast fungus--a pathogenic fungal species that causes the "rice blast" infection in rice crops--switches to the "glyoxylate cycle" when the nutrient source starts to deplete. | |
