A Toll‐like receptor in horseshoe crabs
Immunological Reviews, 2004Summary: Non‐self‐recognition of invading microbes relies on the pattern‐recognition of pathogen‐associated molecular patterns (PAMPs) derived from microbial cell‐wall components. Insects and mammals conserve a signaling pathway of the innate immune system through cell‐surface receptors called Tolls and Toll‐like receptors (TLRs).

Histones from spermatozoa of the horseshoe crab
Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, 1982Abstract It is shown that histones are the nuclear proteins present in spermatozoa of the horseshoe crab Limmulus polyphemus , an arthropod which is considered a living fossil. They have been characterized and found to be closely related to calf thymus histones.

Horseshoe Crabs and Shorebirds
2002Horseshoe crabs are among the oldest creatures on the planet—their fossil evidence dates from 250 million years ago. Within this span, thousands of species of animals have become extinct, while horseshoe crab populations have survived. However, currently horseshoe crab populations are threatened by anthropogenic activities.

Horseshoe crabs are one of evolution's success stories. These living fossils have contributed immensely to biomedical research, and their eggs are a critical link in the migration cycle of New World waders (shorebirds) Can they endure threats posed by a growing commercial fishery and the loss of essential spawning habitats?

Limulus has been a superb animal model for understanding vision in higher animals, including man. Nobel-prize winning research on the lateral eye of Limulus by H. K. Hartline revealed fundamental principles of retinal function applicable to all eyes. The function of the Limulus lateral eye is now well understood as is its essential role in the animal’s

Transportation of Oyster Drills by Horseshoe "Crabs"
Science, 1962Horseshoe "crabs" ( Limulus polyphemus ) collected in New Haven Harbor, Long Island Sound, had large numbers of oyster drills attached to them. Since these animals migrate long distances, they may be important distributors of oyster drills.

Innate Immunity in the Horseshoe Crab
2003Arthropod horseshoe crabs belong to the class Merostomata and are phylogenetically more related to Arachnoidea than Crustacea. Many fossils of horseshoe crabs can be found, primarily in deposits from the Paleozoic era to the Cenozoic era of North America and Europe.

[Cultivation of horseshoe crab amebocytes].
Gaoxiong yi xue ke xue za zhi = The Kaohsiung journal of medical sciences, 1990The in vitro and in vivo cultivation of horseshoe crab amebocytes is studied. Partial bleeding promotes the proliferation of horseshoe crab amebocytes, and could be a useful method for amebocyte production in vivo. The optimal conditions of in vitro cultivation of amebocytes were incubation at 15 degrees C and pH delta 6.8-7.2.
