Protecting Horseshoe Crab Habitat
Each spring adult horseshoe crabs migrate from deep bay waters and the Atlantic continental shelf to intertidal sandy beaches to spawn. Horseshoe crabs are an important food source for migrating shorebirds that feed on the eggs, for migrating fish that feed on the eggs and larvae and for Atlantic loggerhead turtles that feed on horseshoe crabs while using the Chesapeake Bay as a summer nursery ...
متن کاملEvolution and phylogeny of defense molecules associated with innate immunity in horseshoe crab.
This short review describes the molecular evolution and phylogeny of various defense molecules participating in the host defense of horseshoe crab. It is well known that invertebrate animals, which lack adaptive immune systems, have developed various defense systems, so called innate immunity, that respond to common antigens on the surface of potential pathogens. The systems include hemolymph c...
متن کاملHemocyanin of the Horseshoe Crab, Limzdus polyphemus
The high molecular weight hemocyanin found in the hemolymph of the horseshoe crab, Limulus polyphemus, is composed of at least eight different kinds of subunits. Ion exchange chromatography at high pH in the presence of EDTA yields five major zones, hemocyanins I to V, three of which are electrophoretically heterogeneous. The subunits have similar molecular weights, 65,000 to 70,000, and their ...
متن کاملMolecular phylogeny of Ephippidae (Actinopteri: Acanthuriformes)
The family Ephippidae consists of eight genera and 15 species. The genus Platax with five species distributed throughout Indo-Pacific, seemingly has more diversity than other genera of the family. Phylogenetic relationships among species and genera of the family, however, are not fully resolved. 48 sequences of eight species (four genera) of batfishes are available in the GenBank and have been ...
متن کاملA Recombinant Horseshoe Crab Plasma Lectin Recognizes Specific Pathogen-Associated Molecular Patterns of Bacteria through Rhamnose
Horseshoe crab is an ancient marine arthropod that, in the absence of a vertebrate-like immune system, relies solely on innate immune responses by defense molecules found in hemolymph plasma and granular hemocytes for host defense. A plasma lectin isolated from the hemolymph of Taiwanese Tachypleus tridentatus recognizes bacteria and lipopolysaccharides (LPSs), yet its structure and mechanism o...
