      Revision01-October-2007 RFH
      Descriptionα-Toxin causes internucleosomal DNA degradation in T lymphocytes by forming small transmembrane pores. Many cell types are sensitive to cytolysis by α-toxin. Under certain conditions, nucleated cells can be treated with α-toxin without causing lysis. Under controlled conditions, α-toxin monomers bind to the cell membrane and form a hexamer, which functions as a hydrophilic pore with a 1-3 nm diameter. The cell becomes permeable to small molecules, while large molecules, such as enzymes or carbohydrates are excluded. The molecular weight cut-off of material passing through the pore is approximately 2-4 kDa. The pore is somewhat ion selective. Other agents commonly used for permeabilizing cells form large lesions in the membrane, making them permeable to macromolecules. α-Toxin has been utilized to introduce ions, substrates, inhibitors, nucleotides, and other pharmacological agents into cells, thereby regulating cell physiology or function. For example, the arachidonic acid cascade (and subsequent production of prostaglandin I2) is triggered by α-toxin and PMNs in endothelial cells when pores are formed that allow the passive influx of Ca2+. Stimulates prostaglandin synthesis and enhances phosphorylation of myelin basic protein.
