Structural and functional differences of Litopenaeus vannamei crustins
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2004Penaeid crustins were described in Litopenaeus vannamei and L. setiferus as proteins belonging to an antibacterial peptide family with similar sequences but different sizes. Six crustin-coding clones were isolated from a cDNA library from L. vannamei hemocytes, sequenced and compared.

White Shrimp Litopenaeus vannamei
2017The importation of shrimp into Japan at more than 250,000 tons/year is thought to be related in certain aspects to the serious environmental problems that have been caused by shrimp farming in Southeast Asian countries. This includes mangrove deforestation and marine pollution due to the discharge of wastes and leftover feed from intensive and semi ...

Activity of trypsin from Litopenaeus vannamei
Aquaculture, 2009Abstract The trypsin of Litopenaeus vannamei is a polymorphic molecule. Three sequences are translated in the digestive gland of this species. In some individuals, there are 2 isozyme forms and others have 3 that form 3 trypsin phenotypes. Changes in the activity of trypsin do not occur because they turn off or on a specific isozyme, but the ...

Noradrenaline modulates the immunity of white shrimp Litopenaeus vannamei
Fish & Shellfish Immunology, 2006The total haemocyte count (THC), phenoloxidase activity, respiratory burst, superoxide dismutase (SOD) activity, phagocytic activity and clearance efficiency in response to pathogen Vibrio alginolyticus were measured when the white shrimp Litopenaeus vannamei (18.4 +/- 1.2 g) were injected individually with noradrenaline at 10(-8), 10(-7) and 10(-6 ...

N-terminal diversity of Litopenaeus vannamei hemocyanin and immunity
Molecular Immunology, 2019Hemocyanin is primarily a respiratory copper-containing glycoprotein present in the hemolymph of mollusks and arthropods. Recently, hemocyanin has attracted huge research interest due to its multifunctionality and polymorphism. Most previous immune-related studies on shrimp hemocyanin have focused on the C-terminal.

Evidences of abundant hemocyanin variants in shrimp Litopenaeus vannamei
Molecular Immunology, 2016Hemocyanin (HMC) is a multifunctional immune molecule present in mollusks and arthropods and functions as an important antigen non-specific immune protein. Our previous evidences demonstrated that Litopenaeus vannamei HMC might display extensive molecular diversities.

Molecular cloning and expression of NOS in shrimp, Litopenaeus vannamei
Fish & Shellfish Immunology, 2010The importance of the nitric oxide synthase (NOS) gene family is demonstrated by many studies in recent years. However, the lack of sequence information and clones of shrimp NOS cDNA limits further study on its characterization and function in this species.
