Toll receptors are cell-surface receptors acting as pattern recognition receptors (PRRs) that are involved in the signaling pathway for innate immunity activation and are genetically conserved from insects to mammals. Tolls from penaeid shrimp are found in white leg shrimp Litopenaeus vannamei (lToll) and black tiger shrimp Penaeus monodon (PmToll). However, the molecular ligand-recognition patterns and identification of these penaeid Toll classes remain unknown. Here, we report cDNA cloning of a new type of Toll receptor gene (MjToll) from kuruma shrimp, Marsupenaeus japonicus, and the modulation of expression by immunostimulation. The full length cDNA of MjToll gene has 3095 nucleotides coding for a putative protein of 1009 amino acids. The MjToll gene is constitutively expressed in the gill, gut, lymphoid organ, heart, hematopoietic organ, hemocyte, ventral abdominal nerve cord, eyestalk neural ganglia and brain tissues. The MjToll gene expression was significantly increased (76-fold) as compared to a control in lymphoid organ stimulated with peptidoglycan at 12h, in vitro. lToll gene showed high similarity to PmToll gene with 96.9% identity; however, MjToll gene exhibited a percentage identity of 59% with that of penaeid Toll homologues. Therefore, this suggests that the identified MjToll gene belongs to the other class of Toll receptors in shrimp.
