Figure Lengend Snippet: a IHC staining with TβRI-specific antibody to detect the distribution of TβRI + cells in colorectal liver metastases ( n = 36 patients). Representative IHC image. Scale bar, 50 μm. The bar chart in the right represents the percentage of high and low TβRI expression cases in liver metastasis, adjacent and distal liver tissues. p < 0.001 by two-sided Pearson’s chi-square test. b Overall survival curves based on adjacent liver TβRI expressed level in CRLM patients using the multivariate COX regression analysis, a two-sided P -value of < 0.05 was considered statistically significant. c Representative images depicting multicolor immunohistochemical co-staining of TβRI with specific cell type markers in CRLM adjacent liver tissues (DAPI: cell nucleus, HNF4α: hepatocytes, α-SMA: hepatic stellate cells, CD68: macrophages, PAN-CK: tumor cells). Scale bar, 25 μm. d Experimental scheme for generating TβRI flox/flox Alb-Cre +/- ( TβRI-hKO ) mice. TβRI flox/flox Alb-Cre -/- and C57BL/6 J were used as TβRI-hWT mice. e Representative bioluminescent image and Quantification of TβRI-hWT versus TβRI-hKO mice inoculated with MC38-Luc cells ( n = 6 mice/group). f Representative macroscopic image of ( e ) and Quantification of Liver to body weight ratio (LBR). g Representative bioluminescent image of TβRI-hWT versus TβRI-hKO mice inoculated with PAN02-Luc cells ( n = 5 mice/group). h Quantification of ( g ). i Representative macroscopic image of ( g ) and Quantification of LBR. j Representative bioluminescent image of TβRI-hWT versus TβRI-hKO mice inoculated with B16F10-Luc cells ( n = 5 mice/group). k Quantification of ( j ). l Representative macroscopic image of ( j ) and Quantification of LBR. Data are presented as the mean ± SD, and were analyzed with an unpaired two-sided Student’s t test ( e–l ). Consistent results were observed across three biological replicates in ( e–l ).

Article Snippet: The above findings prompted us to explore whether therapeutic interventions, specifically Galectin-9 neutralization (αGal-9) or TβRI inhibition (Galunisertib) , would similarly alleviate liver metastasis by reshaping CD8 + T cell responses in our mouse model.
