Summary: In this study, the effects of nitrite and microplastic stress on the gills of Litopenaeus vannamei were investigated. Both nitrite and microplastic stress caused deformation and vacuolization of the gills, as well as induced oxidative stress. Metabolism of carbohydrates, lipids and amino acids were altered and specific metabolite markers were identified. The expression of certain genes in the PPAR signaling pathway also differed. These findings demonstrate the adverse effects of nitrite and microplastic stress on the gill physiological homeostasis of L. vannamei.

Summary: This study evaluated the effects of microplastics (MPs) and hexabromocyclododecane (HBCD), alone or in combination, on the hepatopancreas of whiteleg shrimp. The results showed evident histological injury, elevation in hepatic lesion markers, disruption of metabolism and detoxification processes, alterations in antioxidant enzymes, and oxidative damage to the hepatopancreas. Furthermore, accumulation of HBCD in shrimp and increased toxicity of HBCD-MP coexposure were observed.

Summary: This study found that insulin-like peptide (ILP) in Pacific white shrimp, Litopenaeus vannamei, regulates hemolymph glucose stability by regulating the expression of glucose metabolism genes, playing a conserved role similar to insulin in vertebrates.

Summary: Leucine promotes protein deposition and glucose metabolism through the TOR signaling pathway in Pacific white shrimp. Appropriate dietary leucine supplementation improves protein synthesis and glucose utilization by maintaining the integrity of hepatopancreas. The leucine requirement of Litopenaeus vannamei is estimated to be 2.60%-2.67% of the diet (6.67%-6.88% of dietary protein) based on regression analysis.

Summary: This study evaluates the effects of microplastic exposure through diet on Litopenaeus vannamei shrimp for seven days. Results show that microplastics were detected in the shrimp's gills, muscles, and hepatopancreas, and caused disruption in redox cells, lipid and DNA damage, as well as histopathological alterations such as edema and granuloma formation. These findings suggest that microplastic exposure can impact the health and welfare of L. vannamei shrimp and potentially affect the final consumers.

Summary: In this study, the toxic effects of NOD on shrimp were investigated. Exposure to NOD resulted in significant histopathological damage, elevated oxidative stress, altered gene transcription, disturbed metabolism, and changes in intestinal microbiota. These findings provide valuable insights into the harmful effects of NOD on shrimp and identify potential biomarkers.

Summary: The combination of acute cold and waterless duration is the major environmental stress for shrimp L. vannamei during live transport. This study aimed to clarify the responding mechanism of L. vannamei to this stress through ultrastructural observation and transcriptomic analysis. The results showed that oxidative stress significantly affected amino acid and energy metabolism, while inflammation and apoptosis pathways played important roles in stress-induced ultrastructural damage.

Summary: In this study, the immunotoxicity of silver nanoparticles on whiteleg shrimp was assessed by monitoring the activity of certain enzymes, as well as the changes in antioxidant capacity and oxidative damage markers. It was found that silver nanoparticles caused severe immunotoxicity in the hepatopancreas tissue of whiteleg shrimp through the suppression of certain enzymes and antioxidant capacity.

Summary: The study evaluated the effects of different concentrations of chitosan supplementation from shrimp tailings on the antioxidant and immune systems of Litopenaeus vannamei in a BFT system, finding that dietary intake of chitosan could enhance antioxidant defenses, with at least 1 g kg(-1) chitosan showing potential to improve defense mechanisms and stress resistance in aquaculture.

Summary: In this study, a novel GPX gene (LvGPX3) was discovered in Litopenaeus vannamei, which plays a crucial role in enhancing the shrimp's immune response against white spot syndrome virus (WSSV) and Vibrio alginolyticus infection. LvGPX3 expression is accelerated by oxidative stress or infection, and it promotes the expression of antimicrobial peptide genes, thereby increasing the shrimp's resistance to pathogens. This finding is important for understanding the immune mechanism in shrimp.

Summary: This study examined the effects of short-term exposure to ammonia on stress and oxidative responses in shrimp. The results showed that exposure to high ammonia content led to oxidative stress and inflammation, with both enzymatic and nonenzymatic antioxidant defense systems being involved. These systems were regulated by heat shock proteins (HSPs) and certain transcription factors.

Summary: Endoplasmic reticulum (ER)-stress is an important cause of aquatic animal diseases. This study investigated the influence of ER-stress in Litopenaeus vannamei using RNA-Seq, and identified differentially expressed genes (DEGs) related to ER-stress, immune, and metabolism. The study also suggested that ER-stress might play an important role in the immune response of shrimp.

Summary: The study aimed to investigate the effects of bile acids supplementation in low fishmeal diets on sterol metabolism, bile acids enterohepatic circulation, bile acid profile, and apoptosis in Pacific white shrimp Litopenaeus vannamei. The results showed that the supplementation of bile acids enhanced growth performance, promoted sterol metabolism, enhanced enterohepatic circulation, and reduced apoptosis in shrimp on low fishmeal diets.
