We previously demonstrated that F. nucleatum binds and activates the human inhibitory receptors TIGIT and CEACAM1 leading to inhibition of T and NK cell anti-tumor immunity. CEACAM1 was found to be bound and activated by the fusobacterial trimeric autotransporter adhesin CbpF. Here we report the generation of a recombinant E. coli expressing full-length CbpF that efficiently binds and activates CEACAM1.</p>application/pdfenCreative Commons Attribution 4.0 InternationalF. nucleatumCbpFtrimeric autotransporter adhesinCEACAM1NK cellsArticle - Refereedhttps://doi.org/10.3389/fcimb.2021.6990151134395310
