Summary of "An attenuated Vibrio harveyi surface display of envelope protein VP28 to be protective against WSSV and vibriosis as an immunoactivator for Litopenaeus vannamei."

Surface display can expose foreign antigenic protein on the surface of the vaccine vector, which is promising choice to elicit better immune responses. In this study, we apply this strategy to develop an immunoactivator by using a live attenuated Vibrio harveyi as an antigenic protein carrier with surface displayed VP28, a major envelope protein of white spot syndrome virus (WSSV), for two major pathogens of Litopenaeus vannamei. As a result, the immunoactivator showed self-limited growth and attenuation of virulence in shrimp via different inoculation routes either with single-repetitive dose or high dose. Moreover, either intramuscular injection or oral administration of the immunoactivator did not affect growth of shrimp body weight or cause pathologic changes. Additionally, the rapid immunoprotection was induced by the immunoactivator after administration for one week with highly relative percent survival (RPS) more than 90% against both V. harveyi and WSSV. Until 4 weeks post administration, the immunoactivator still possessed efficient immune effect with no less than 60% RPS for both pathogens. Totally, the attenuated V. harveyi surface displaying VP28 could be a potential immunoactivator for WSSV and vibriosis control in L. vannamei.

Medical and Biotech [MESH] Definitions

An envelope protein of the human immunodeficiency virus that is encoded by the HIV env gene. It has a molecular weight of 160,000 kDa and contains numerous glycosylation sites. It serves as a precursor for both the HIV ENVELOPE PROTEIN GP120 and the HIV ENVELOPE PROTEIN GP41.

External envelope protein of the human immunodeficiency virus which is encoded by the HIV env gene. It has a molecular weight of 120 kDa and contains numerous glycosylation sites. Gp120 binds to cells expressing CD4 cell-surface antigens, most notably T4-lymphocytes and monocytes/macrophages. Gp120 has been shown to interfere with the normal function of CD4 and is at least partly responsible for the cytopathic effect of HIV.

The visual display of data in a man-machine system. An example is when data is called from the computer and transmitted to a CATHODE RAY TUBE DISPLAY or LIQUID CRYSTAL display.

A strain of the VIBRIO CHOLERAE bacteria belonging to serogroup non-O1, infecting humans and other PRIMATES. It is related to VIBRIO CHOLERAE O1, but causes a disease less severe than CHOLERA. Eating raw shellfish contaminated with the bacteria results in GASTROENTERITIS.

Transmembrane envelope protein of the HUMAN IMMUNODEFICIENCY VIRUS which is encoded by the HIV env gene. It has a molecular weight of 41,000 and is glycosylated. The N-terminal part of gp41 is thought to be involved in CELL FUSION with the CD4 ANTIGENS of T4 LYMPHOCYTES, leading to syncytial formation. Gp41 is one of the most common HIV antigens detected by IMMUNOBLOTTING.
