Abstract

Recent clinical studies have reinforced the importance of sex-related differences in the pathogenesis of cardiovascular diseases, with an increased incidence and mortality in men. Similar to humans, male BALB/c mice infected with coxsackievirus B3 (CVB3) develop more severe inflammation in the heart even though viral replication is no greater than in females. We show that TLR4 and IFN-γ levels are significantly elevated and regulatory T cell (Treg) populations significantly reduced in the heart of males following CVB3 infection, whereas females have significantly increased T cell Ig mucin (Tim)-3, IL-4 and Treg. Blocking Tim-3 in males significantly increases inflammation and TLR4 expression while reducing Treg. In contrast, defective TLR4 signaling significantly reduces inflammation while increasing Tim-3 expression. Cross-regulation of TLR4 and Tim-3 occurs during the innate and adaptive immune response. This novel mechanism may help explain why inflammatory heart disease is more severe in males.

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.
