== Publication Abstract from PubMed ==
Drosophila Toll receptors are involved in embryonic development and the immune response of adult flies. In both processes, the only known Toll receptor ligand is the human nerve growth factor-like cystine knot protein Spatzle. Here we present the crystal structure of a 1:1 (nonsignaling) complex of the full-length Toll receptor ectodomain (ECD) with the Spatzle cystine knot domain dimer. The ECD is divided into two leucine-rich repeat (LRR) domains, each of which is capped by cysteine-rich domains. Spatzle binds to the concave surface of the membrane-distal LRR domain, in contrast to the flanking ligand interactions observed for mammalian Toll-like receptors, with asymmetric contributions from each Spatzle protomer. The structure allows rationalization of existing genetic and biochemical data and provides a framework for targeting the immune systems of insects of economic importance, as well as a variety of invertebrate disease vectors.
