Project description:Shrimp allergy is the second most common food allergy in the United States. γδ T cells play a regulatory role in peanut immunotherapy, but their role in shrimp allergy remains unclear. We hypothesized γδ T cells play a regulatory role in shrimp allergic disease. We performed single cell RNA sequencing on peripheral cells from shrimp allergic (SA) and healthy control (HC) subjects after stimulation with shrimp tropomyosin. We found significant expansion of γδ T cells and three distinct clusters. One γδ T cell cluster predominated in SA, characterized as CD8+ with a cytotoxic expression profile. We found significant upregulation of TGF-β1 and downregulation of IL-7R in SA-stimulated vs. HC-stimulated γδ T cells, and IL-10 secretion in stimulated SA γδ T cells. γδ T cells play an important role in the pathogenesis of shrimp allergy through lymphocyte-mediated cytotoxin signaling and cytokine-mediated signaling pathways, including TGFβ-1, IL7/TSLP-IL7R, and IL10-IL10R pathways.

Project description:Acute hepatopancreatic necrosis disease (AHPND) is a shrimp farming disease, caused by a pathogenic Vibrio parahaemolyticus carrying a plasmid encoding Vp_PirAB-like toxin (VpAHPND). Whiteleg shrimp, Litopenaeus vannamei were fed food pellets containing formalin-killed VpAHPND (FKC-VpAHPND) to select for toxin resistance. To identify genes associated with Vp_PirAB-like toxin resistance, total RNA was sequenced to identify differentially expressed genes (DEGs) in the stomach and hepatopancreas among surviving shrimp (sur-FKC), AHPND-infected shrimp (Vp-inf) and normal shrimp (control). From a total of 79,591 genes, 194 and 224 DEGs were identified in the stomach and hepatopancreas transcriptomes, respectfully. The expressions of DEGs were validated by qPCR of ten genes. Only one gene, a gene homologous to L vannamei anti-lipopolysaccharide factor AV-R isoform (LvALF AV-R), was expressed significantly more strongly in sur-FKC than in the other groups. The association of LvALF AV-R expression and toxin resistance was affirmed from the surviving shrimp in a second-trial of FKC-VpAHPND feeding. These results suggest that LvALF AV-R may be involved in shrimp defense mechanisms against Vp_PirAB-like toxin virulence.

Project description:Adult male grass shrimp were exposed for 96 hours to LC50 concentrations of either Fipronil, Endosulfan, or Cadmium, as well as a Carrier Control exposure. RNA was extracted from whole-body homogenates using the RNABee kit. Tags were clustered to identify tags diagnostic of the different exposures. Keywords: SAGE, Grass shrimp, ecotoxicogenomics 3 randomly selected shrimp were pooled for each library. Libraries were constructed using the I-SAGE long kit from Invitrogen.

Project description:Vibrio parahaemolyticus is a Gram-negative bacterium commonly found in marine and estuarine environments. Acute hepatopancreatic necrosis disease (AHPND) caused by this bacterium is an ongoing problem among shrimp farming industries. V. parahaemolyticus proteins PirA and PirB have been determined to be major virulence factors that induce AHPND. In this study, Pacific white shrimp (Litopenaeus vannamei) were challenged with recombinant PirA and PirB by a reverse gavage method and then at 30 m, 1, 2, 4, and 6 h time points, the hepatopancreas of five individual shrimp were removed and placed into RNA later. We conducted RNA sequencing of the hepatopancreas samples from a no PirA/B control (n = 5) and PirA/B-treated shrimp at the different time intervals (n=5). We evaluated the different gene expression patterns between the time groups to the control with a focus on identifying differences in innate immune function.

Project description:To present, the only known inv*olvement of the gills in the immune response of shrimp is solely assisting the hemocytes in filtering out the harmful factors. This global expression of novel genes revealed several immune-related genes specifically expressed in high amounts only in gills. This data provide new insights on the immune defense of shrimp.
