BmPGRP-L4 drives antibacterial activity and prophenoloxidase pathway activation in the silkworm Bombyx mori.
Peptidoglycan recognition proteins (PGRPs) are a family of pattern recognition receptors that play critical roles in detecting bacterial infections and activating immune responses in insects. Although twelve PGRPs have been identified in the silkworm Bombyx mori, the functions of most long-type PGRPs, including BmPGRP-...
