Summary of "The immune functions of sessile hemocytes in three organs of kuruma shrimp Marsupenaeus japonicus differ from those of circulating hemocytes."

Shrimp, as invertebrates, have an open vasculature that allows circulating hemocytes to infiltrate the tissues, where they are referred to as sessile hemocytes. Sessile hemocytes are known to express immune-related genes, but it is not known whether their functions differ from those of circulating hemocytes. To answer this question, we enriched them from suspensions of different tissues using discontinuous density gradient centrifugation and analyzed their transcripts by RNA-seq. The results suggest that circulating hemocytes and sessile hemocytes of the gills are in a state that could react quickly to pathogens, immune-related genes expression of sessile hemocytes differ from circulating hemocytes, and the gills, heart and lymphoid organs have cells that express immune-related genes that are different from hemocytes.

Medical and Biotech [MESH] Definitions

One of the largest orders of mostly marine CRUSTACEA, containing over 10,000 species. Like AMPHIPODA, the other large order in the superorder Peracarida, members are shrimp-like in appearance, have sessile compound eyes, and no carapace. But unlike Amphipoda, they possess abdominal pleopods (modified as gills) and their bodies are dorsoventrally flattened.

An order of mostly marine CRUSTACEA containing more than 5500 species in over 100 families. Like ISOPODA, the other large order in the superorder Peracarida, members are shrimp-like in appearance, have sessile compound eyes, and no carapace. But unlike Isopoda, they possess thoracic gills and their bodies are laterally compressed.

A family of CRUSTACEA, order DECAPODA, comprising the penaeid shrimp. Species of the genus Penaeus are the most important commercial shrimp throughout the world.

Specialized organs adapted for the reception of stimuli by the NERVOUS SYSTEM.

Organs involved in the production of BLOOD, including the cellular and the molecular components essential in providing defense against foreign organisms or substances.
