Yin and Yang: The dual effects of interferons on hematopoiesis
Open accessAbstract
Interferons are an ancient and well-conserved group of inflammatory cytokines most famous for their role in viral immunity. A decade ago, we discovered that interferons also play an important role in the biology of hematopoietic stem cells (HSCs), which are responsible for lifelong blood production. Though we have learned a great deal about the role of interferons on HSC quiescence, differentiation, and self-renewal, there remains some controversy regarding how interferons impact these stem cells, with differing conclusions depending on experimental models and clinical context. Here, we review the contradictory roles of Type 1 and 2 interferons in hematopoiesis. Specifically, we highlight the roles of interferons in embryonic and adult hematopoiesis, along with short-term and long-term adaptive and maladaptive responses to inflammation. We discuss experimental challenges in the study of these powerful yet short-lived cytokines and strategies to address those challenges. We further review the contribution by interferons to disease states including bone marrow failure and aplastic anemia as well as their therapeutic use to treat myeloproliferative neoplasms and viral infections, including SARS-CoV2. Understanding the opposing effects of interferons on hematopoiesis will elucidate immune responses and bone marrow failure syndromes, and future therapeutic approaches for patients undergoing HSC transplantation or fighting infectious diseases and cancer.

The mouse experiments recapitulate chronic inflammation through induction of multiple pro-inflammatory cytokines known to be increased in the serum of patients with MPN, including IFNγ.
“These experiments recapitulate chronic inflammation through induction of multiple pro-inflammatory cytokines34,35 known to be increased in the serum of patients with MPN36, including IFNγ (Fig. 5a and Extended Data Fig. 10a).”
From Single-cell multi-omics identifies chronic inflammation as a driver of TP53-mutant leukemic evolution (2023) · cites this paper as [34]
The Introduction’s section on short- versus long-term interferon signaling describes persistent IFNγ signaling in mouse infection models, supporting the inflammatory IFNγ component. It does not establish that the citing paper’s mouse experiments induced multiple pro-inflammatory cytokines or recapitulated chronic inflammation in that way. The separate claim about cytokines in MPN patient serum is attached to citation 36, not this source. (LLM, conf=0.82)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
