Abstract:There are several explanations for the extinction of ancient giant insects. Here, we present a new hypothesis suggesting that the innate immune system limits the body sizes of insects. In this study, we co-cultured bacteria, fungi, and insect blood cells, and performed single-cell RNA sequencing analyses of insect blood cells to determine their division of labor. In the innate immune system, prohibited molecules are listed as signals of invasion. The increasing diversity of organisms makes this list extensive.… Show more
