Calpain activity during the initial invasion of C. parvum.
A. Western blot analysis showing time dependent autolysis of the 80 kDa of catalytic subunit of calpain 1 after initial C. parvum (Cp) infection. B. Calpain activity of Caco-2 cells exposed to heat killed or live C. parvum for 1 hour. The data are representative of three independent experiments.
