RIG-I-like receptor activation drives type I IFN and antiviral signaling to limit Hantaan orthohantavirus replication.

abstract：:Phospoenolpyruvate carboxylase (PEPC) is absent from humans but encoded in the Plasmodium falciparum genome, suggesting that PEPC has a parasite-specific function. To investigate its importance in P. falciparum, we generated a pepc null mutant (D10(Δpepc) ), which was only achievable when malate, a reduction product o...
