Abstract:
The immune system is a critical system in evolutionary biology, shaped by coevolution between hosts and pathogens. The frog Xenopus is a valuable model organism for studying this process, offering insights into amphibian development, immunity, and the evolutionary dynamics of the interferon (IFN) response and viral interactions. The role of Xenopus IFN and the viral mimics introduced during the development of the immune system is discussed in this review, and the roles they played in the study of host-pathogen interactions and in the replication of genes that allowed the development and complexity of the immune system are reflected. We discussed the molecular mechanisms of Xenopus IFN signaling and the emergence of viral mimics in evolutionary biology. This review offers insight into how immune systems evolve under the pressure of pathogens, and the understanding of Xenopus IFN, its viral mimics, and that of other leading players in the vertebrate immune system may have further applications in medicine and biotechnology. Xenopus is a good model for studying the evolutionary dynamics of immune systems. In conclusion, this review posits that further elucidation of vertebrate immune adaptation mechanisms-particularly the evolutionary refinement of IFN-mediated antiviral restriction pathways, as demonstrated by Xenopus IFNs counteracting viral molecular mimics-will critically inform the rational design of next-generation antiviral pharmacotherapies, structure-guided vaccine adjuvants, and targeted immunomodulatory biologics.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
