LAMTOR1/mTORC1 promotes CD276 to induce immunosuppression via PI3K/Akt/MMP signaling pathway in Clostridium perfringens-induced necrotic enteritis of laying hens.

ABSTRACT: Clostridium perfringens (C. perfringens) causes avian necrotic enteritis, leading to huge economic losses to the poultry industry. This pathogen induces host immunosuppression; however, the molecular mechanism is still unclear. Thus, we established a laying hen infection model to explore this mechanism. We randomly divided 20 one-old-day laying hens into the control and infection groups. The infection group was infected intragastrically with 1 × 10⁹ colony-forming units of C. perfringens in 1 mL of sterile phosphate-buffered saline (PBS) once a day from d 17 to 20; the control group received the same volume of PBS without the bacterium. Twenty-four hours after the last challenge, we sacrificed the laying hens and collected the jejunum for analysis. The infection group presented
