Effect of cyclosporine A and oligomycin on non-specific permeability of the inner mitochondrial membrane.
The effect of oligomycin and cyclosporine A on the induction of non-specific permeability of the inner mitochondrial membrane by Ca2+ was under study. Both oligomycin and cyclosporine A were able to prevent the activation of non-specific permeability, but cyclosporine A was the only agent which could restore initial permeability of the inner mitochondrial membrane. The effect of cyclosporine A was shown not to be mediated through redistribution of Ca2+ between different mitochondrial subpopulations.
