Reversible cell damage by T-cell perforins. Calcium influx and propidium iodide uptake into K562 cells in the absence of lysis.
The non-lethal effects of the lymphocyte-derived pore-forming toxin perforin on the human erythroleukaemia cell line K562 were investigated. By using the fluorescent Ca2+ indicator fura-2, perforin was shown to cause intracellular Ca2+ concentration to rise transiently into the micromolar range in t...
