Here I consider the hypothesis that type I interferons promote bacterial replication by impairing key antibacterial immune responses, including those orchestrated by interleukin-1 and interferon γ. Paradoxically, during tuberculosis, the underlying state of impaired antibacterial immunity co-exists with overt (but ineffective) inflammation.

This essay explores the hypothesis that macrophages play a crucial protective role in premalignant tissues by sensing and responding to early oncogenic transformation. Their activity is closely intertwined with cell-intrinsic barriers to transformation — such as apoptosis, senescence, and DNA repair — which collectively work to suppress malignant progression. Thus, an integrated cell-intrinsic and macrophage response constitutes effective ‘oncogenic monitoring’. In premalignant tissues, macrophages interpret outputs of cell-intrinsic tumor suppression as oncogenic stress signals detected through innate immune sensors, initiating a protective, homeostatic response that mitigates potential progression to malignancy. By recontextualizing macrophage roles in the early immune landscape, it becomes evident that these cells can serve as key protectors, preventing or delaying tumor formation. Understanding this dual role of macrophages — protective in early tumorigenesis and protumorigenic in established cancers — offers new perspectives on harnessing their immune functions for cancer prevention and therapy.</div></div>","PeriodicalId":11361,"journal":{"name":"Current Opinion in Immunology","volume":"92 ","pages":"Article 102524"},"PeriodicalIF":6.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent advances highlight the critical roles played by bioactive metabolites in regulating hematopoiesis. In particular, secreted immune metabolites (SIMets), such as γ-aminobutyric acid (GABA) and acetylcholine, secreted by B-lineage cells, act as potent modulators of hematopoietic processes, influencing HSC differentiation and emergency hematopoiesis. In this review, we provide an overview and discuss mechanisms by which energy metabolism and SIMets regulate hematopoiesis.
