Here we characterized the immune landscape of pulmonary tissues from a Mycobacterium abscessus-infected NTM mice model. Interleukin-17 (IL-17)A<sup>+</sup> γδ T cells were essential for controlling M. abscessus infection by directly eliminating extracellular bacteria. These cells conferred protective immunity in two mouse models of infection combined with either pulmonary fibrosis or a lack of functional interferon-gamma (IFNγ)-mediated immunity.

Absence of IL-17A substantially impaired bacterial recognition and cytotoxic function of IL-17A<sup>+</sup> γδ T cells, highlighting the cell-intrinsic requirement for IL-17A signalling in γδ T cell activation. M. abscessus recognition through Toll-like receptor 2 induced macrophage production of IL-1β and IL-23, promoting the expansion and activation of IL-17A<sup>+</sup> γδ T cells. Single-cell RNA sequencing on human peripheral blood mononuclear cells suggests that anti-IFNγ autoantibodies compromise γδ T cell function.

This bacterium causes a destructive infection of skin and soft tissue called Buruli ulcer. Here we ran a randomized controlled trial in an urban Buruli ulcer endemic area in Melbourne, Australia to test whether autodissemination mosquito control stations, containing pyriproxyfen (larvicide) and Beauveria bassiana (entomopathogenic fungus), suppress Ae. notoscriptus populations. Six geographic areas each received 100 autodissemination stations for 8 weeks, and six control areas received no stations between 25 January 2024 and 21 March 2024. The primary outcome measure was mosquito population numbers. After the trial, there was a 70% average reduction in mosquito egg counts among the six intervention areas compared to control areas (P = 0.0076). In an ad hoc analysis, we then explored human Buruli ulcer notifications in treatment and control areas. After accounting for the 4.8-month mean incubation period, there was an 83% reduction in infection likelihood coinciding with peak intervention effect (intervention zones 1 case, control zones 6 cases, incidence ratio rate 0.167, 95% CI 0.0026–1.054, P = 0.047). The effect was not observed during the same time period in the year previous or following 2024, when no interventions were undertaken. A strong correlation (R2 = 0.85) was observed between decreased disease risk and mosquito suppression. These data show that autodissemination traps can effectively lower urban mosquito populations and reduce the threat of Buruli ulcer in humans. A randomized controlled trial shows that autodissemination stations reduce egg counts for Aedes notoscriptus, the Mycobacterium ulcerans vector, with exploratory analyses suggesting that the intervention could also reduce human Buruli ulcer cases caused by these bacteria, in intervention areas in Melbourne, Australia.","PeriodicalId":18992,"journal":{"name":"Nature Microbiology","volume":"11 9","pages":"2493-2504"},"PeriodicalIF":18.7,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41564-026-02439-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148838419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
