FIG 2.

Western blot analysis of pyrin S205 dephosphorylation in BMDMs. LPS-primed BMDMs were left uninfected, infected with Y. pseudotuberculosis strain IP6ΔM harboring an empty vector or IP6ΔM/pYopE or intoxicated with TcdB for 90 min. (A and B) Lysates were processed with nondenaturing NP-40 lysis buffer and separated into soluble and insoluble fractions by centrifugation. (C) Lysates were processed with denaturing RIPA lysis buffer, and the soluble fractions were collected. Samples were subjected to Western blotting using antibodies to pSer205 of pyrin, total pyrin, or β-actin.
