Regulatory B Cells: Origin, Phenotype, and Function
Open accessAbstract
Regulatory B (Breg) cells are immunosuppressive cells that support immunological tolerance. Through the production of interleukin-10 (IL-10), IL-35, and transforming growth factor β (TGF-β), Breg cells suppress immunopathology by prohibiting the expansion of pathogenic T cells and other pro-inflammatory lymphocytes. Recent work has shown that different inflammatory environments induce distinct Breg cell populations. Although these findings highlight the relevance of inflammatory signals in the differentiation of Breg cells, they also raise other questions about Breg cell biology and phenotype. For example, what are the functional properties and phenotype of Breg cells? Can a Breg cell arise at every stage in B cell development? Is inflammation the primary requisite for Breg cell differentiation? Here, we use these questions to discuss the advances in understanding Breg cell biology, with a particular emphasis on their ontogeny; we propose that multiple Breg cell subsets can be induced in response to inflammation at different stages in development.

In mice, Bregs can arise from various developmental stages including B1 B cells, transitional B cells, marginal zone B cells, follicular B cells and plasmocytes.

From Is there a role for B cells in Alzheimer's disease? (2026) · cites this paper as [62]
The Introduction (page unavailable) says that immature and mature B cells and plasmablasts can differentiate into IL-10-producing Breg cells in mice, and it describes transitional marginal-zone precursor cells and regulatory plasma cells. It does not specifically establish B1, follicular, and marginal-zone B cells as separate origins in the claimed list; it also says the developmental links among Breg subsets remain unknown.

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.
