Compared with infection with PA alone, transfection with pcDNA-NRIP1 further attenuated cell viability and aggravated cell apoptosis and inflammation, and transfection with si-NRIP1 improved cell viability (Figure 1B) and reduced cell apoptosis (Figure 1C) and inflammation (Figure 1D, 1E). Here, NRIP1 is linked to infection.
