Figure Lengend Snippet: a – e , The morphological traits of YB328. a , Left, scanning electron microscopy image. Scale bar, 1 µm. Right, transmission electron microscopy image of negatively stained cells. The arrows indicate extracellular membrane vesicles secreted by YB328. Scale bar, 0.5 µm. b , d , Relative abundances of YB328 ( b ) and P. vulgatus ( d ) in faecal samples of patients shown in Fig. ( n = 50). c , e , ROC curves (left) and Kaplan—Meier curves (right) of the PFS of patients with high or low abundances of YB328 ( c ) or P. vulgatus ( e ) in faeces. f , g , Tumour growth curves of SPF mice with B16F10 ( f ) or MC38 ( g ) tumours (left, summary; right, each mouse). n = 4–6 mice per group. Here and in other figures, control indicates mice treated with an isotype control antibody. h – j , The frequency (representative staining (left) and summary (right)) of PD-1 ( h , n = 8), CD62L and CD44 ( i , n = 7) and IFNγ and TNF production ( j , n = 7) by CD8 + T cells in MC38 tumours. Cells were gated on CD8 + TILs ( h – j ). k – m , The mean fluorescent intensity (MFI) of CD86 ( k , n = 6), CD40 ( l , control or anti-PD-1, n = 3, P. vulgatus or YB328, n = 4) and H-2Kb (a marker for MHCI) ( m , n = 6) by CD11c + MHCII + DCs in MC38 tumours. n – p , Tumour growth curves ( n , n = 5–7 mice per group), TCR Vβ repertoire ( o ) and numbers of skewed TCR Vβ clones (>10% of each clone) ( p ) among PD-1 + CD8 + T cells ( n = 5 mice per group). For b and d , each dot indicates one patient, and the data are presented as the median. For f (left), g (left) and n , the average tumour sizes of the groups on a certain day are shown as dots and are presented as the mean ± s.d. For h – m and p , each dot in the summary graphs indicates one mouse. Data are presented as the mean ± s.d. ( h – m ) or median ( p ). Significance was assessed using two-sided Mann—Whitney U -test ( b , d , p ), two-sided log-rank test ( c , right, e , right), two-way analysis of variance (ANOVA) with the Tukey—Kramer method ( f , g , n ) or one-way ANOVA with Bonferroni correction ( h – m ).
Article Snippet: The mouse colon cancer cell line MC38 (ENH204, Kerafast) and the mammary carcinoma cell line EMT6 (CRL-2755, ATCC) were cultured in high-glucose DMEM (Fujifilm Wako Pure Chemical) supplemented with 10% FBS (Biosera) and 2 mM l -glutamine.
