Hypervirulent M. tuberculosis W/Beijing Strains Upregulate Type I IFNs and Increase Expression of Negative Regulators of the Jak-Stat Pathway
Abstract
The role of type I interferons (IFNs) in the host response to bacterial infections is controversial. Here, we examined the role of IFN-alpha/beta in the murine response to infection with Mycobacterium tuberculosis, using wildtype mice, mice with impaired signaling through the type I IFN receptor (IFNAR), and mice treated to reduce levels of type I IFNs. In this study, we used virulent clinical isolates of M. tuberculosis, including HN878, W4, and CDC1551. Our results indicate that higher levels of type I IFNs are induced by the HN878 and W4 strains. Induction of type I IFNs was associated with lower levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin- 12 (IL-12) and reduced T cell activation, and associated with decreased survival of the mice infected with HN878 or W4 relative to infection with CDC1551. Infection of mice with HN878 and W4 was also associated with relatively higher levels of mRNA for a number of negative regulators of the Jak-Stat signaling pathway, such as suppressors of cytokine signaling (SOCS) 1, 4, and 5, CD45, protein inhibitor of activated Stat1 (PIAS1), protein tyrosine phosphatase nonreceptor type 1 (Ptpn1), and protein tyrosine phosphatase nonreceptor type substrate 1 (Ptpns1). Taken together, these results suggest that increased type I IFNs may be deleterious for survival of M. tuberculosis-infected mice in association with reduced Th1 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.
