Insects have a more complex immune system than previously thought according to a new study published in the journal Science. Researchers from the University of Arizona have discovered that insects have an immune system that is surprisingly similar to that of vertebrates. This discovery has implications for the development of treatments for infectious diseases in both humans and bugs.

Insects have long been thought to have a simpler immune system than vertebrates, but the University of Arizona researchers have found that this is not the case. The team found that insects possess an array of receptors and signaling pathways that are similar to those found in humans, such as Toll-like receptors, cytokines, and other signaling molecules. This suggests that insects may be better equipped to fight off infections than previously thought.
