Intravenous anesthetic propofol suppresses T cell-dependent antibody production in mice.
Article in Journal of anesthesia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeGeneral anesthesia combined with surgery is thought to suppress the immune system. However, few studies have examined the effects of anesthetics alone on humoral immunity. In this study, we aimed to investigate the effects of the intravenous anesthetic propofol on antibody production after immunization and the underlying mechanisms in mice.
methodsMice were immunized with 4-hydroxy-3-nitrophenylacetyl (NP) hapten-conjugated keyhole limpet hemocyanin (NP-KLH), a T cell-dependent antigen, or NP hapten-conjugated Ficoll (NP-Ficoll), a T cell-independent antigen, followed by treatment with propofol, or PBS or intralipid as controls, for five consecutive days. The mice were re-immunized, and antibody production and immune cell subsets were evaluated. The effects of propofol on T cell proliferation and survival were also examined.
resultsNP-specific IgM and IgG1 titers were reduced in propofol-treated NP-KLH-immunized mice compared to those treated with PBS or intralipid, and this reduction was more pronounced in the secondary response than in the primary response. By contrast, propofol treatment did not affect NP-specific antibody titers in NP-Ficoll-immunized mice. In vitro, propofol inhibited IL-2-mediated proliferation and IL-7-dependent survival of CD4
conclusionsPropofol suppresses T cell-dependent antibody production in mice and directly affects T cell proliferation and survival in vitro. These data suggest that anesthetics administered close to the time of vaccination may affect vaccine-specific antibody production.
