Distinct Functions of Bombyx mori Peptidoglycan Recognition Protein 2 in Immune Responses to Bacteria and Viruses
In conclusion, we cloned two forms of BmPGRP2 generated from different TIS and characterized their distinct functions in the host immune response to pathogens (Figure 7). Our findings indicate that BmPGRP2-2 does not function in canonical immune signaling pathways and PGRP2 is not only involved in host immune defense against invading pathogens, but is also used by viruses to evade host antiviral mechanisms.
