Abstract

The chemokine receptor CXCR4 is expressed in B cells at multiple stages of their development. CXCR4 function in humoral immunity has not been fully investigated. We have generated gene-targeted mice in which CXCR4 can be selectively inactivated in B cells and have shown that it is required for retention of B cell precursors in the bone marrow. CXCR4-deficient B cell precursors that migrated prematurely became localized in splenic follicles despite their unresponsiveness to CXCL13. Concomitantly, mature B cell populations were reduced in the splenic marginal zone and primary follicles, and in the peritoneal cavity in the mutant animals, as were T-independent antibody responses. In addition, aberrant B cell follicles formed ectopically in intestinal lamina propria around Peyer's patches. These findings establish an important role for CXCR4 in regulating homeostasis of B cell compartmentalization and humoral immunity.

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.
