Summary: The aquaculture industry has faced financial losses due to disease outbreaks, particularly in the Macrobrachium rosenbergii aquaculture industry. Understanding the host's defense mechanism is crucial for providing effective defense measures. This study used RNA-seq technology to investigate the immune pathways and genes related to innate immunity in hemocytes from M. rosenbergii. The results identified differentially expressed genes and revealed their involvement in antibacterial activities against gram-positive bacteria. These findings contribute valuable data for disease prevention and provide a basis for improved prevention strategies.

Summary: The cytokine Astakine, identified in the freshwater prawn Macrobrachium rosenbergii, plays an important role in promoting the proliferation and differentiation of hematopoietic stem cells and regulating immune responses. Knockdown of MrAst, the homolog of Astakine, increases susceptibility to bacterial and viral infections and affects the functionality and apoptosis of hemocytes.

Summary: This study used RNA-seq to analyze the transcriptomes of Macrobrachium rosenbergii hemocytes after Vibrio parahaemolyticus challenge. The results showed significant differential gene expression in both 6 and 12 hours after challenge, with immune-related pathways being affected. qRT-PCR confirmed the activation of immune response in M. rosenbergii after V. parahaemolyticus infection. These findings provide new insights into the immune system of M. rosenbergii and suggest a potential approach to combat bacterial infections.

Summary: This study showed that IS increases O-2(-) production in vascular tissues, attenuating ACh- and SNP-induced vasorelaxation via potential NO inactivation. Additionally, IS-promoted O-2(-) production in the presence of vascular endothelium is likely through binding to AhR and activation of NADPH oxidase.

Summary: In living organisms, most oxygen is reduced to water through four-electron reduction, but a small percentage is reduced through one-electron mechanisms to produce reactive oxygen and nitrogen species. These species interact with various components of living organisms, leading to diverse effects on biological systems.

Summary: This study investigated the levels of superoxide anion, nitric oxide, and peroxynitrite in the digestive fluid of the carnivorous pitcher plant. The presence of reactive oxygen species and reactive nitrogen species was found, and their occurrence was related to the scavenging capacity and phenolics content. Nitric oxide emission was higher in the fed traps compared to the unfed ones, and the concentration of nitrite decreased in the fed traps, indicating it as the main source of nitric oxide. The presence of ROS and RNS was observed even in closed traps, suggesting their involvement in both digestion and signaling during trap development.

Summary: DA, an important neurotransmitter, can modulate NO production in immune cells through adrenergic receptors in ascidian animals. The presence of catecholaminergic receptors on ascidian immune cells suggests unique pharmacological characteristics that may have evolutionary significance.

Summary: White tail disease is caused by Macrobrachium rosenbergii nodavirus (MrNV) and an extra-small virus (XSV). This study detected MrNV in both adult and post-larval prawns, while XSV was not detected. Although no gross signs of the disease were observed, histopathological changes were found in the muscle of adult and post-larval prawns.

Summary: Passive acoustics monitoring has been used to detect crustacean feeding activity. This study evaluated the sound emission of the giant freshwater prawn during feeding commercial food, identifying the sound structure and parameters. The study found that the prawn emits click sounds while consuming food, with some acoustic parameters varying among size classes.

Summary: A variant of the Macrobrachium rosenbergii golda virus (MrGV) was found in Chinese prawns and compared with a variant reported in Bangladesh. Although there is currently no evidence that this variant causes disease, it is important to be vigilant as it may lead to mass death of prawn larvae.

Summary: A novel ssDNA virus, Macrobrachium hepatopancreatic bidnavirus (MHBV), was identified in giant freshwater prawn using metagenomic analysis and de novo assembly. This virus showed circular, eosinophilic inclusions in the nuclei of hepatopancreatic cells. The MHBV genome closely matched the polymerase B gene in the V1 fragment of Bombyx mori bidensovirus 2 (BmBDV2) and belongs to the family Bidnaviridae.

Summary: The lymphatic system plays a crucial role in immune surveillance and tissue homeostasis, and lymphangiogenesis, the formation of new lymphatic vessels, is involved in various physiological and pathological processes. Recent research progress in the molecular mechanisms of lymphangiogenesis has opened up new possibilities for therapeutic approaches in diseases such as neurological disorders, cardiac repair, autoimmune disease, obesity, and atherosclerosis.

Summary: A novel virus, named infectious precocity virus (IPV), belonging to the family Flaviviridae, was identified in prawns with the iron prawn syndrome (IPS). The discovery of IPV provides new insight into the pathology and sexual maturation in crustaceans, calling for quarantine inspection in transboundary trade of live M. rosenbergii and enhanced surveillance of IPV in aquaculture globally.
