RESEARCH PROGRESS IN THE INNATE IMMUNITY OF PENAEID SHRIMP AND ITS POTENTIAL APPLICATION IN AQUACULTURE

Shrimp aquaculture plays very important roles for providing high-quality proteins to people. However, with the development of aquaculture, disease problem become the major obstacles to hinder the sustainable development of shrimp culture industry. Understanding the immunity of shirmp is the basis for disease control. Shrimp belongs to invertebrate which has only innate immunity. In the last two decades, researchers have paid more attention on the innate immunity of shrimp, and a series progress have been made. In our group, EST sequencing, cDNA microarray, RNA seq. and proteinomics approach were used to screen the genes related to bacterial and viral infection and the functions of the related genes were analyzed. Based on the accumulating data obtained in our group and other researcher in China, we summaried the outlines of humoral immunity and cellular immunity of shrimp. On the basis of these works, we specifically focused on the functions of immune effectors and developing genetic markers related to disease resistance. These information will not only enrich the knowledge of immunity in crustacean, but also provide instructions to disease control and genetic breeding of shrimp.
