Abstract

Trained immunity defines the long-term memory of innate immunity based on innate immune signalling, metabolic changes and epigenetic rewiring of trained innate immune cells, which are characterised by elevated inflammatory responses towards secondary stimuli. The activation of this non-specific protection-mediated memory in innate immune cells was identified to benefit host defences as well as play a detrimental role in inflammatory diseases. In this review, we focused on summing up the current progress about the inducers, effector cells, molecular mechanisms and protective effects of trained immunity that have been identified in both mammals and teleost fish, and discussing the future research and application of trained immunity in aquaculture. Revealing the mechanisms of trained immunity will not only provide a novel aspect for understanding the evolution of innate immune memory and their longer-term protections, but also contribute to the rational design and evaluation of immunopotentiators, adjuvants and potential vaccines in aquaculture.

Abstract

The cathode in lithium-selenium (Li-Se) batteries has garnered extensive attention owing to its superior specific capacity and enhanced conductivity compared to sulfur. Nonetheless, the adoption and advancement of Li-Se batteries face significant challenges due to selenium's low reactivity, substantial volume fluctuations, and the shuttle effect associated with polyselenides. Single-atom catalysts (SACs) are under the spotlight for their outstanding catalytic efficiency and optimal atomic utilization. To address the challenges of selenium's low chemical activity and volume expansion in Li-Se batteries, through electrospun, we have developed a lotus root-inspired carbon nanofiber (CNF) material, featured internal multi-channels and anchored with molybdenum (Mo) single atoms (Mo@CNFs). Mo single atoms significantly enhance the conversion kinetics of selenium (Se), facilitating rapid formation of Li2Se. The internally structured multi-channel CNF serves as an effective host matrix for Se, mitigating its volume expansion during the electrochemical process. The resulting cathode, Se/Mo@CNF composite, exhibits a high discharge specific capacity, superior rate performance, and impressive cycle stability in Li-Se batteries. After 500 cycles at a current density of 1 C, it maintains a capacity retention rate of 82% and nearly 100% coulombic efficiency (CE). This research offers a new avenue for the application of single-atom materials in enhancing advanced Li-Se battery performance. [ABSTRACT FROM AUTHOR]
