Abstract

We have previously shown that during an infection with Leishmania major, susceptible BALB/c mice, as opposed to mice of a resistant strain (C57BL/6), are primed by lipopolysaccharide for the production of high levels of tumor necrosis factor‐α (TNF‐α) which is known to be a potent macrophage (MΦ) stimulator in other parasitic diseases. In the present study we investigated whether TNF‐α activates MΦ for killling of L. major parasites. In the absence of interferon‐γ (IFN‐γ) or lipopolysaccharide, TNF‐α (0.025—25000 U/ml) failed to activate peritoneal exudate MΦ from BALB/c micefor killling of L. major amastigotes. In the presence of suboptimal doses of IFN‐γ (5 or 10 U/ml), however, TNF‐α mediated a rapid elimination of intracellular parasites, which was highly significant compared to IFN‐γ alone. The combination of TNF with interleukin 4, in contrast, was inactive in this respect and allowed survival of intracellular parasites. From these data we conclude that thepresence of IFN‐γ is curcial for TNF‐α‐mediated killing of L. major parasites by MΦ. Disease progression in susceptible mice thereforeseems to be a consequence of a deficiency of IFN‐γ and a predominance of interleukin 4 rather than the result of an excess amount of TNF‐α.

  • IFNγ co-operates with other TH1 cell cytokines and acts synergistically to enhance their ability to eliminate pathogens.

    “It is worth noting that IFNγ co-operates with other TH1 cell cytokines and acts synergistically to enhance their ability to eliminate pathogens31,32.”

    From An Omicron-specific, self-amplifying mRNA booster vaccine for COVID-19: a phase 2/3 randomized trial (2024) · cites this paper as [31]

    Section 3.2 reports a synergistic anti-parasitic effect of IFN-γ and TNF-α: together they reduced L. major parasites in murine macrophages when either cytokine alone was ineffective at the tested doses. The Concluding remarks suggest this synergy may matter for protection against other intracellular parasites, but the paper does not establish synergy with TH1 cytokines generally or elimination of pathogens generally.

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.
