Stanford scientists have completed the first global census of diverse proteins sprouting tree-like from the outer membrane of a cell. These cell surface proteins govern how cells interact with one another and how they assemble into tissues and organs such as hearts and brains.
 
 
    KeysightImportance of Microglia in Neurodegenerative Disease and Immunity
 
Microglia are a form of tissue specific macrophage. In the central nervous system, they are one of the primary forms of immune defense. Microglia are of increasing interest to researchers studying neurodegenerative disease and development of drugs.

Study uncovers how rice blast fungus uses its own cell wall to launch an attackIn 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”).
 
 
 How to Analyze Cell-Nanoparticle Interactions
 
How to Analyze Cell-Nanoparticle InteractionsThe 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.

Discovery of cellular 'hands' could have implications in the fields of cell, developmental biologyThe protein, called syndecan-4, combines with fellow cell membrane proteins, called integrins, to form protruding 'hands' that sense the environment outside the cell.
 
 
 Extremely low concentrations of acetic acid could alter cellular processes in rice blast fungus
 
Extremely low concentrations of acetic acid could alter cellular processes in rice blast fungusAll 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.
