Table 1. Immune gene groupings based on immune process and functional class.
Immune process | Genes | Basic role(s) |
---|---|---|
Cellular | 131 | Hemocyte-mediated responses to all classes of parasites and pathogens |
Encapsulation | 36 | Initial recognition and coating of parasitoid wasp eggs |
Phagocytosis | 45 | Cellular uptake of bacteria, fungi, and necrotic cells |
Epithelial | 30 | Regulation of bacteria and fungi on epithelial surfaces, including the gut, trachea, and reproductive tract |
Humoral | 141 | Recognition and elimination of bacteria and fungi in the hemolymph through the production of antimicrobial compounds |
IMD | 57 | Humoral pathway that targets mainly Gram-negative bacteria |
Toll | 61 | Humoral pathway that targets mainly Gram-positive bacteria and fungi |
JAK-STAT | 26 | Signaling pathway implicated in viral response, control of hemocyte differentiation, and regulation of humoral response |
JNK pathway and wound repair | 44 | Epithelial repair and cell growth |
Melanization and PO production | 32 | Cell-mediated response that responds to wounding and the detection of parasitoid wasp eggs and microbes |
ROS production | 14 | Production of reactive oxygen species; especially key in epithelial immune regulation |
Viral defense | 29 | Destruction of viruses through RNAi; elimination of virus-infected cells |
Functional class | Genes | Basic role(s) |
Recognition | 58 | Initial detection of invading parasites and pathogens. Includes cell-surface (e.g., phagocytosis) receptors as well as humoral-response pattern recognition proteins (e.g., GNBPs and PGRPs) |
Signaling | 198 | Signal transduction following pathogen recognition; negative regulation of immune response; cross talk between pathways |
Effector | 75 | Pathogen destruction or sequestration. Includes AMPs, lysozymes, and ROS |
ROS, reactive oxygen species; GNBPs, Gram-negative bacteria binding proteins; PGRPs, peptidoglycan recognition proteins.
