Fig. 7From: PD-1/PD-L1 axis induced host immunosuppression via PI3K/Akt/mTOR signalling pathway in piglets infected by Glaesserella ParasuisDetermination of the PI3K/Akt/mTOR signaling pathway activation in the spleen by G. parasuis. The PI3K, Akt, and mTOR expressions at mRNA A-C and protein levels D-G were detected by RT-PCR and Western blot, respectively. **p < 0.01*; ***p < 0.001Back to article page
