Besides  the kidney of fish is considered as a functional ortholog of mammalian bone marrow that serves as a hematopoietic hub for generating blood cell lineages and immunological responses. However  knowledge about the properties of kidney hematopoietic cells  and the functionality of kidney in fish immune systems remain to be elucidated. To this end  our present study generated a comprehensive atlas with 59 hematopoietic stem/progenitor cell HSPC and immune cell types from zebrafish kidney via single cell transcriptome profiling analysis. These populations included almost all known cells associated with innate and adaptive immunity  and displayed differential responses to viral infection  indicating their diverse functional roles in antiviral immunity. Remarkably  HSPCs were found to have extensive reactivities to viral infection  and the trained immunity can be effectively induced in certain HSPCs. In addition  the antigen stimulated adaptive immunity can be fully generated in kidney  suggesting kidney acting as a secondary lymphoid organ. These results indicated that fish kidney is a dual functional entity with functionalities of both primary and secondary lymphoid organs. Our findings illustrated the unique features of fish immune system  and highlighted the multifaced biology of kidney in ancient vertebrates.
