Ge Q, Wang J, Li J, Li J. Effect of high alkalinity on shrimp gills: Histopathological alternations and cell specific responses. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2023; 256:114902. [PMID: 37062262 DOI: 10.1016/j.ecoenv.2023.114902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 10/20/2022] [Accepted: 04/09/2023] [Indexed: 06/19/2023]
Abstract
High alkalinity stress was considered as a major risk factor for aquatic animals surviving in saline-alkaline water. However, few information exists on the effects of alkalinity stress in crustacean species. As the dominant role of gills in osmotic and ionic regulation, the present study firstly evaluated the effect of alkalinity stress in Exopalaemon carinicauda to determine changes in gill microstructure, and then explore the heterogeneity response of gill cells in alkalinity adaptation by single-cell RNA sequencing (scRNA-seq). Hemolymph osmolality and pH were increased remarkably, and gills showed pillar cells with more symmetrical arrangement and longer lateral flanges and nephrocytes with larger vacuoles in high alkalinity. ScRNA-seq results showed that alkalinity stress reduced the proportion of pillar cells and increased the proportion of nephrocytes significantly. The differentially expressed genes (DEGs) related to ion transport, especially acid-base regulation, such as V(H+)-ATPases and carbonic anhydrases, were down-regulated in pillar cells and up-regulated in nephrocytes. Furthermore, pseudotime analysis showed that some nephrocytes transformed to perform ion transport function in alkalinity adaption. Notedly, the positive signals of carbonic anhydrase were obviously observed in the nephrocytes after alkalinity stress. These results indicated that the alkalinity stress inhibited the ion transport function of pillar cells, but induced the active role of nephrocytes in alkalinity adaptation. Collectively, our results provided the new insight into the cellular and molecular mechanism behind the adverse effects of saline-alkaline water and the saline-alkaline adaption mechanism in crustaceans.

Comparative effects of different bacterial lipopolysaccharides on modulation of immune levels to improve survival of the black tiger shrimp. J Invertebr Pathol 2023; 197:107872. [PMID: 36566013 DOI: 10.1016/j.jip.2022.107872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 12/15/2022] [Accepted: 12/19/2022] [Indexed: 12/24/2022]
Abstract
To prevent loss from disease, immunostimulants have been used as dietary supplements to improve immunity and survival of shrimps. Among the various types of immunostimulants, there is increasing evidence that a diet enriched with bacterial lipopolysaccharide can reduce the mortality rate of shrimp under exposure to pathogens. Here, the immunostimulatory effects of bacterial lipopolysaccharide (LPS) from various bacterial sources were explored. Bacterial LPS was extracted from a shrimp pathogen, Vibrio harveyi and its effects were compared with the commercially available LPS from the non-shrimp pathogen, Escherichia coli. Our results revealed that the LPS from V. harveyi was different in molecular size but contained similar functional groups to that from E. coli. To understand their molecular mechanisms, bacterial LPS from the two sources were applied as a supplementary diet and fed to juvenile shrimp for 4-week feeding period before tissue samples were collected for transcriptomic analysis by next generation sequencing. Gene expression profiling revealed that major immune-related genes such as pattern recognition proteins (PRPs), proteinases and proteinase inhibitors, prophenoloxidase systems (proPO system), antimicrobial peptides (AMPs), signaling transduction pathways, heat shock proteins (HSPs), oxidative stress responses, and other immune-related molecules such as mucins and peritrophins were modulated in the groups of shrimp fed with bacterial LPS from both sources, but at different levels. The results suggest that bacterial LPS could modulate shrimp immune system, and different LPS sources led to different activation of immune pathways. Additionally, metabolic-related genes were affected by LPS, suggesting that energy was required for immune stimulation. In the V. harveyi pathogen challenge trial, all shrimp groups fed with diets containing LPS from both bacterial sources showed better survival than the control group without LPS. When comparing groups fed with LPS supplemented diets, the higher concentration of LPS (8 μg/body weight) from E. coli resulted in a better survival rate than a lower concentration (4 μg/body weight). Conversely, shrimp fed with a diet containing LPS from V. harveyi showed a lower survival rate when a higher dose of LPS (8 μg/body weight) was administered than the group fed with a lower concentration of LPS (4 μg/body weight). This could be due to overstimulation of shrimp immune responses, especially by LPS derived from shrimp pathogens, resulting in a reverse effect. These results confirm that immunity in shrimp upon administration of bacterial LPS depends on the origin and dose of the LPS administered.

Abstract
The cell types and developmental trajectories of shrimp cells based on the transcriptional level have not been established, and gene expression profile and function at the single-cell level is unclear. We aimed to use scRNA-seq to construct a single-cell resolution transcriptional map of hepatopancreas and haemocytes in shrimp to analyse the molecular mechanisms of the immune response to ammonia nitrogen stress. In the present study, seven cell clusters were successfully identified in each of the two tissues (haemocytes, Hem1-7; hepatopancreas, Hep1-7) based on specifically-expressed marker genes. The developmental starting points of haemocytes and hepatopancreatic cells were Hem2 and Hep1, respectively. We propose that Hem2 has oligopotent potential as the initiation site for haemocyte development and that Hem4 and Hem5, located at the end of development, are the most mature immune cell types in haemocytes. Hep5 and Hep6 were the developing terminal cells of hepatopancreas. The antioxidant system and proPO system of shrimp were activated under ammonia nitrogen stress. A large number of DEGs were involved in oxidative stress, detoxification metabolism, and immune defence. In particular, important response genes such as AMPs, proPO, and GST were not only marker genes for identifying cell groups but also played an important role in shrimp cell differentiation and functional plasticity. By successfully applying 10× Genomics based scRNA-seq to the study of shrimp, the single-cell transcriptional profiles of hepatopancreatic cells and haemocytes of shrimp innate immune responses under ammonia stress were constructed for the first time. This atlas of invertebrate hepatopancreatic cells and haemocytes at single-cell resolution identifies molecular events that underpin shrimp innate immune system responses to stress.

Abstract
Granulocytes and plasmatocytes play important roles in clearing foreign objects in insects, but it is difficult to distinguish between them in immune reactions. Based on the hemocyte cell line SYSU-OfHe-C established at our lab, two cell sublines, SYSU-OfHe-C Granulocyte (Gr cells) and SYSU-OfHe-C Plasmatocyte (Pl cells), which possess the morphological characteristics of granulocytes and plasmatocytes, respectively, were established. Gr and Pl cells showed different behaviors in immune reactions, such as spreading, phagocytosis and encapsulation. Pl cells were easier to spread, but Gr cells tended to undergo aggregation, indicating that they may take different strategies to clear foreign objects. These results also suggested that granulocytes and plasmatocytes may express some different proteins. By comparing the gene expression in cells from the two sublines, 1662 differentially expressed genes were identified, and 13 out of 30 transmembrane proteins highly expressed in Pl cells (six) or Gr cells (seven) were further screened and confirmed by reverse-transcription polymerase chain reaction (PCR). Finally, three transmembrane genes specifically expressed in Pl cells and two transmembrane genes specifically expressed in Gr cells were screened out based on their expressions in immune reactions by quantitative PCR analysis. These genes may potentially be used as molecular markers to distinguish between granulocytes and plasmatocytes in Ostrinia furnacalis, and further to clarify the functions of immune hemocytes in cellular immune reaction such as encapsulation and so on.

Abstract
Crustacean aquaculture is expected to be a major source of fishery commodities in the near future. Hemocytes are key players of the immune system in shrimps; however, their classification, maturation, and differentiation are still under debate. To date, only discrete and inconsistent information on the classification of shrimp hemocytes has been reported, showing that the morphological characteristics are not sufficient to resolve their actual roles. Our present study using single-cell RNA sequencing revealed six types of hemocytes of Marsupenaeus japonicus based on their transcriptional profiles. We identified markers of each subpopulation and predicted the differentiation pathways involved in their maturation. We also predicted cell growth factors that might play crucial roles in hemocyte differentiation. Different immune roles among these subpopulations were suggested from the analysis of differentially expressed immune-related genes. These results provide a unified classification of shrimp hemocytes, which improves the understanding of its immune system.

Abstract
Hemocytes in shrimp play important roles in innate immune responses against pathogens. Although three types of hemocytes including hyalinocytes, semi-granulocytes and granulocytes were identified based on their morphological characters in penaeid shrimp, knowledge about the molecular basis of their functions in the immunity is still very limited. In the present study, three subpopulations of hemocytes were firstly separated by Percoll gradient centrifugation, and their transcriptomes were analyzed. The data showed that significantly differential gene expression patterns existed in different types of hemocytes. The genes encoding phagocytic receptors, lectins and actin cytoskeleton involved in phagocytosis were highly expressed in hyalinocytes, while genes involved in the humoral immunity signaling pathways were highly expressed in semi-granulocytes, and genes encoding prophenoloxidase (proPO)-activating enzyme and serine proteases involved in proPO system activation were highly expressed in granulocytes. Further flow cytometry analysis indicated that hyalinocytes were the main hemocytes subpopulation responsible for ingesting foreign fluorescent beads, and this ingestion process mainly depends on the endocytic way of macropinocytosis. These data provide valuable information for understanding the molecular basis of distinct shrimp hemocytes subpopulations of shrimp in cellular and humoral immunity.
