Marine organisms are threatened by various environmental contaminants, and nanoplastics (NPs) is one of the most concerned. Studied have shown that NPs has a certain impact on marine organisms, but the specific molecular mechanism is still unclear. At present, researches on the effect of NPs on marine life mostly focus on crustaceans, gastropods, and bivalves. In this study, cephalopod Sepia esculenta larvae were first used to investigate the potential immune response molecular mechanisms caused by PS-NPs (50 nm, 50 mg/L) short-term exposure (4 and 24 h). Through S. esculenta larvae transcriptome profile of gene expression analysis, 548 and 1990 genes showed differential expression at 4 and 24 h after NPs exposure, respectively. GO and KEGG enrichment analysis were performed to find immune related DEGs. Then, the interaction relationship between the immune related DEGs after NPs exposure was known through the constructed protein-protein interaction network. 20 hub genes were found on the base of KEGG pathway numbers involved and protein-protein interaction numbers. This research supply valuable genes for the study of cephalopod immune response caused by NPs, which can help us further uncover the molecular mechanisms of organism against NPs.

Article Synopsis
- Talisia esculenta, a fruit tree native to Brazil, is utilized in traditional medicine for its leaves, which may help treat conditions related to oxidative stress and inflammation, such as rheumatic diseases and hypertension.
- The study aims to evaluate the antioxidant and anti-inflammatory properties, as well as the safety of various extracts from T. esculenta leaves and fruit peels.
- Results showed that the extracts possess low toxicity, with protective effects against oxidative stress, successfully reducing reactive oxygen species (ROS) levels in zebra fish larvae and macrophages.

The golden cuttlefish () is an important cephalopod species with a lifespan of approximately one year. The species plays a crucial role in marine ecological support services and is commercially valuable in fisheries. In the seas around China, this species has emerged as the main target for cuttlefish fisheries, replacing since the 1990s.
