An Integrin from Shrimp Litopenaeus vannamei Mediated Microbial Agglutination and Cell Proliferation

An Integrin from Shrimp Litopenaeus vannamei Mediated Microbial Agglutination and Cell Proliferation

BACKGROUND Integrins are a family of adhesion receptors which regulate cell proliferation, differentiation, leukocyte migration, and complement receptor-dependent phagocytosis. In invertebrates, as a cell adhesion receptor, β integrins play an important role for the balanced activation of immune defense responses especially during the encounter of infections. The present study attempts to chara...

Microbiota from Litopenaeus vannamei: digestive tract microbial community of Pacific white shrimp (Litopenaeus vannamei)

Bacteria capable of producing different extracellular enzymes of potential relevance in digestive processes were isolated from the stomach, hepatopancreas and intestine of Pacific white shrimp Litopenaeus vannamei. A total of 64 strains with proteolytic activity were isolated and grouped into 16 clusters based on morphological characteristics: 4 groups were isolated from the intestine; 5 from t...

Enzyme assisted extraction of chitin from shrimp shells (Litopenaeus vannamei)

8 BACKGROUND: Chemical chitin extraction generates large amounts of wastes and increases partial 9 deacetylation of the product. Therefore, the use of biological methods for chitin extraction is an 10 interesting alternative. The effects of process conditions on enzyme assisted extraction of chitin from 11 the shrimp shells in a systematic way were the focal points of this study. 12 RESULTS: De...

Hemocyanin from Shrimp Litopenaeus vannamei Has Antiproliferative Effect against HeLa Cell In Vitro

Hemocyanin (HMC) has been shown to participate in multiple roles of immune defence. In this study, we investigated the antiproliferative effect and underpinning mechanism of HMC from Litopenaeus vannamei in vitro. Sulforhodamine B (SRB) assay indicated that HMC could dramatically inhibit the growth of HeLa cells, but not 293T cells under the same conditions. Moreover, typical morphological feat...
