“…Simultaneously, we noted that numerous researchers have utilized a similar approach to investigate the bactericidal function of antimicrobial peptides, evaluating their antibacterial activity by directly observing bacterial counts (Zhu et al, 2023).…”

“…This decision was informed by existing literature on type I interferon in grass carp, wherein researchers have demonstrated significant induction of IFN1 expression in blood cells, and a marked enhancement of IFN1-induced phagocytosis in platelets following bacterial injection. The research further detailed the isolation of peripheral blood platelets, which, when stimulated with recombinant IFN1, influenced immune factors and complement components, notably C3.3 (Zhu et al, 2023). Motivated by these findings, we aimed to determine if the bacterial load in the blood would be lower than in other immune tissues and if grass carp IFN-υ might also play a similar role in modulating antibacterial activity.…”

“…Additionally, tissue samples from the control group also contained both sources of A. hydrophila, which leads us to conclude that neither the endogenous A. hydrophila nor the injected bacteria significantly affected the results of our study. Hence, we did not establish specific screening markers for detection before the experiments.Simultaneously, we noted that numerous researchers have utilized a similar approach to investigate the bactericidal function of antimicrobial peptides, evaluating their antibacterial activity by directly observing bacterial counts (Zhu et al, 2023).Reference: Zhu W, Zhang Y, Liao Z, et al 2023. IFN1 enhances thrombocyte phagocytosis through IFN receptor complex-JAK/STAT-complement C3.3-CR1 pathway and facilitates antibacterial immune regulation in teleost.…”

“…Coincidentally, the newly discovered IFN-υ exhibits antiviral functions (Chen et al, 2022). In our previous researches, grass carp IFN1 (a member of type I IFNs) demonstrates antibacterial activity in both in vitro and in vivo (Xiao et al, 2021;Zhu et al, 2023). To date, the biological functions and mechanisms of IFN-υ remain unknown in bacterial infections.…”

“…Unlike direct bactericidal intervention, CiIFN-υ potentially enhances defense by modulating the immune environment. Grass carp type I IFN, for instance, augments platelet phagocytosis through the JAK/STAT-complement C3.3-CR1 pathway, promoting antimicrobial regulation in fish (Zhu et al, 2023). Cytokines such as interferon generally act paracrinally or autocrinally, exerting potent effects even at picomolar concentrations and are predominantly localized, reducing the likelihood of undue inflammation.…”

Dear editor and reviewers, Thank you and reviewers very much for providing us this precious opportunity to revise our manuscript. We appreciate all the kindly, professional and constructive comments. The precious suggestions are very pertinent and important for improving the quality of the manuscript and for our future studies. Following your precious advices, we carefully supplemented the relevant experiments and thoroughly revised the manuscript. Here is a summary of revision and responses. Reviewer #1: Comments to the AuthorThe authors details the discovery of anti-infective immune functions of type IV interferon in grass carp (Ctenopharyngodon idella). The findings of this study are novel and present a significant opportunity to further understand the immune functions of type IV interferon in vertebrates. Overall, the research is cutting-edge. and the data is presented in a logical and systematic manner. However, at the current state, several points need to be revised and added to render the manuscript suitable for publication: Author's Response:We appreciate your professional comments and encouragement. Following your precious advices, we supplemented the required experiments and revised the manuscript thoroughly. 1.It was uncertain which version of the female or male grass carp genome data was used by the authors. It was necessory to provide the website source and reference. Similarly, the version of zebrafish genome still needs to be explained in the analysis of the colinearity blocks of protein between grass carp and zebrafish. Author's Response:Thank you very much for your professional comments and valuable suggestions. In response to your constructive advice, we have supplemented our manuscript with the relevant references to the versions of the grass carp and zebrafish genomes that we utilized.The grass carp genome assembly, HZGC01, was obtained from Professor Yongan Zhang's team at Huazhong Agricultural University. The sequencing tissue for this genome was derived from the blood of an adult female grass carp. Additionally, the genome can be accessed at the following web address: https://www.ncbi.nlm.nih.gov/datasets/genome/GCF_019924925.1/. This particular genome assembly was also employed in the study of the grass carp TLR family (Lv et al., 2023). The zebrafish genome referenced in our collinearity analysis is the Zv9 assembly version (Chen et al., 2022). Corresponding conserved genes in grass carp were identified based on Figure 1. We have included this detailed information in the Materials and Methods section of the main text.Line229, CIK describes the grass carp kidney cell line , the English name is wrong. "C" was standed for the first letter "C" in "Ctenopharyngodon", and "I" was standed for the first letter "I" in "Idella". Furthermore, the resources and culture condition of CIK and FHM cells should be provided. Line 351, spelling error, grass carp genomics should be changed to grass carp genome. And other sites in manuscript should be corrected. Author's Response:We appreciate your professio...
