T. parva infection induces increased levels of IκBα and phosphorylated IκBα and decreased total IκBβ levels. T. parva-infected T cells were left untreated (−) or treated daily with BW720C to clear the parasite (+). Lysates were prepared from 10⁷ cells collected following 1, 2, or 3 days in culture and IκBα and IκBβ levels determined by immunoblot analysis. *P-IκBα designates phosphorylated IκBα.
