Abstract
Litopenaeus vannamei is the major farmed shrimp species worldwide. White spot disease due to white spot syndrome virus (WSSV) is severely affecting shrimp worldwide, causing extensive economic losses in L. vannamei culture. This is the first study that applied combined transcriptomic and metabolomic analysis to study the effects on the L. vannamei hepatopancreas after WSSV challenge. Our transcriptomic data revealed differentially expressed genes (DEGs) associated with immunity, apoptosis, the cytoskeleton and the antioxidant system in the hepatopancreas of L. vannamei. Metabolomic results showed that WSSV disrupts metabolic processes including amino acid metabolism, lipid metabolism and nucleotide metabolism. After challenged by WSSV, immune-related DEGs and differential metabolites (DMs) were detected in the hepatopancreas of L. vannamei, indicating that WSSV may damage the immune system and cause metabolic disorder in the shrimp. In summary, these results provide new insights into the molecular mechanisms underlying L. vannamei's response to WSSV.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2021; 123:104168. [PMID: 34118281 DOI: 10.1016/j.dci.2021.104168] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 06/05/2021] [Accepted: 06/05/2021] [Indexed: 06/12/2023]
Abstract
CD63, a member of the tetraspanin family, is involved in the activation of immune cells, antiviral immunity, and signal transduction. The economically important anemonefishes Amphiprion sp. often face disease outbreaks, and the present study aimed to characterize CD63 in Amphiprion clarkii (denoted AcCD63) to enable better disease management. The in-silico analysis revealed that the AcCD63 transcript is 723 bp long and encodes 240 amino acids. The 26.2 kDa protein has a theoretical isoelectric point of 5.51. Similar to other tetraspanins, AcCD63 consists of four domains: short N-/C-terminal domains and small/large extracellular loops. Pairwise sequence alignment revealed that AcCD63 has the highest identity (100%) and similarity (99.2%) with CD63 from Amphiprion ocellaris. Multiple sequence alignment identified a conserved tetraspanin CCG motif, PXSCC motif, and C-terminal lysosome-targeting GYEVM motif. The quantitative polymerase chain reaction analysis showed that AcCD63 was highly expressed in the spleen and head kidney tissue, with low levels of expression in the liver. Temporal expression patterns of AcCD63 were measured in the head kidney and blood tissue after injection of polyinosinic:polycytidylic acid (poly (I:C)), lipolysacharides (LPS), or Vibrio harveyi (V. harveyi). AcCD63 was upregulated at 12 h post-injection with poly (I:C) or V. harveyi, and at 24 h post-injection with all stimulants in the head kidney. At 24 h post-injection, poly (I:C) and LPS upregulated, whereas V. harveyi downregulated AcCD63 expression in the blood. All viral hemorrhagic septicemia virus transcripts (M, G, N, RdRp, P, and NV) were downregulated in response to AcCD63 overexpression, and removal of viral particles occurred via the involvement of AcCD63. The expression of antiviral genes MX dynamin-like GTPase 1, interferon regulatory factor 3, interferon-stimulated gene 15, interferon-gamma, and viperin in CD63-overexpressing fathead minnow cells was downregulated. Collectively, our findings suggest that AcCD63 is an immunologically important gene involved in the A. clarkii pathogen stress response.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2019; 98:99-107.

Abstract
White spot syndrome, which is caused by white spot syndrome virus (WSSV), is a highly contagious disease of penaeid shrimp. However, there is currently incomplete understanding of the infection mechanism and pathogenesis of WSSV. In this study, a novel gene of a previously uncharacterized WSSV response protein (LvWRP) in Litopenaeus vannamei was identified and characterized. The LvWRP gene has an open reading frame (ORF) of 879 bp encoding a putative protein of 292 amino acids. Sequence analysis revealed that LvWRP shared 24.9% identity with an uncharacterized protein of Penaeus monodon nudivirus. Real-time qPCR analysis showed that LvWRP was ubiquitously expressed in shrimp tissues, with transcript levels induced in hemocytes upon immune challenge with Vibrio parahaemolyticus, Streptoccocus iniae, lipopolysaccharide (LPS), and WSSV. In addition, RNA interference-mediated knockdown of LvWRP followed by WSSV challenge revealed significant decrease in the transcript levels of WSSV IE1 and VP28 genes coupled with a reduction in WSSV copies in shrimp hemocytes. Moreover, depletion of LvWRP followed by WSSV challenge significantly increased the transcript levels of Vago4 and Vago5 as well as increased the phosphorylation of STAT, while hemocytes apoptosis in terms of caspase 3/7 activity was decreased. These results suggest that LvWRP is important for WSSV replication in shrimp, and therefore one of the vital host factors in WSSV infection.

Abstract
The tetraspanins, representing a conserved superfamily of four-span membrane proteins, are highly involved in viral and bacterial infections. Thus far, the function of the tetraspanins in crustaceans remains largely unknown. In this study, we report the cloning and expression analysis of a tetraspanin 8 from the giant freshwater prawn, Macrobrachium rosenbergii (named as MrTspan8). MrTspan8 contains a 720-bp open reading frame encoding a 239-amino acids protein, which exhibits four transmembrane domains and two extracellular loops that are typical for tetraspanins. MrTspan8 was found to be widely expressed in a variety of prawn tissues including heart, gill, muscle, gut, and hepatopancreas. Additionally, MrTspan8 expression was significantly increased in the hepatopancreas and gill of the prawns challenged by the bacterial pathogen Aeromonas hydrophila. Moreover, we show that pre-incubation of the peptides from the large extracellular loop of MrTSPAN8 protein reduced the cell death caused by A. hydrophila infection in prawn tissue, suggesting that MrTSPAN8 could be a mediator for bacterial infection to prawn.

Xie XL, Chang XJ, Gao Y, Li DL, Liu LK, Liu MJ, Wang KJ, Liu HP. An Ns1abp-like gene promotes white spot syndrome virus infection by interacting with the viral envelope protein VP28 in red claw crayfish Cherax quadricarinatus. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2018; 84:264-272. [PMID: 29510164 DOI: 10.1016/j.dci.2018.03.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/31/2018] [Revised: 02/26/2018] [Accepted: 03/01/2018] [Indexed: 06/08/2023]
Abstract
Influenza A virus non-structural-1A binding protein (named as Ns1abp) was originally identified as a host protein from human that bound to the viral NS-1 protein. In our previous study, the expression of an Ns1abp-like gene (denoted as CqNs1abp-like gene) was found to be up-regulated in a transcriptome library from the haematopoietic tissue (Hpt) cells of red claw crayfish Cherax quadricarinatus post white spot syndrome virus (WSSV) infection. To elucidate the role of CqNs1abp-like gene involved in WSSV infection, we cloned the CqNs1abp-like gene in which the open reading frame was 2232 bp, encoding 743 amino acids with two typical domains of one BTB (Broad-Complex, Tramtrack and Bric a brac) domain at N-terminal and six Kelch domains at C-terminal. The gene expression profile showed that the mRNA transcript of CqNs1abp-like gene was widely expressed in all the tested tissues with highest expression in nerve, relatively high expression in Hpt and lowest expression in eyestalk. Importantly, both the WSSV entry and the viral replication were significantly reduced in Hpt cells after gene silencing of CqNs1abp-like gene. By using protein pull-down assay, we found that the recombinant BTB domain, six Kelch domains and CqNs1abp-like intact protein were all bound to the WSSV envelope protein VP28, respectively, in which the BTB domain showed slightly less binding affinity than that of the six Kelch domains or the recombinant intact protein. Besides, the WSSV entry into Hpt cells was clearly decreased when the virus was pre-incubated with the recombinant BTB domain, six Kelch domains, or the recombinant CqNs1abp-like intact protein, respectively, suggesting that the CqNs1abp-like gene was likely to function as a putative recognition molecular towards WSSV infection in a crustacean C. quadricarinatus. Taken together, these data shed new light on the mechanism of WSSV infection and a putatively novel target on anti-WSSV infection in crustacean farming.
