The differentially expressed proteins post-infection include Akap1, Prkaca, Prkab2, Acaca, Acacb, Aka1, Abcf1, Synj1, Braf, Vcl, and Fhod3, which involve insulin receptor signal, glucagon signal pathway, AMPK signal pathway, and Hippo signal pathway. The gene discussed is ACACB; the disease is infection.
