Figure Lengend Snippet: M2pepLNP-siTaf15 shows promise in targeting macrophages for the treatment of ICC. (A,B) In vivo and in vitro small animal imaging was conducted using free IR780 and M2pepLNP/IR780 in ICC mice via the tail vein. (C) Self-luminescence (Dil) with F4/80 multicolor immunofluorescence. (D,E) Western blot and QPCR analysis of Taf15 in BMDM after transfection with small interference for 48 h. (F) A schematic diagram illustrates the encapsulation of siTaf15 by M2pep-liposomes. (G) A schematic diagram depicts the treatment regimen of ICC mice with liposome materials. (H) Differential morphology of the liver is observed after treatment with M2pepLNP coated with siNc and siTaf15. (I) Weight of the liver is measured following treatment with M2LNP coated with siNc and siTaf15. (J) H&E and IHC analyses are conducted for CK19 and TAF15 in liver tissues treated with M2pepLNP-siNc and M2pepLNP-siTaf15. (K) H&E analysis of heart, lung, spleen, kidney in mice treated with M2pepLNP-siNc and M2pepLNP-siTaf15. (L) Flow cytometry analysis the expression of CD206 and CD86 of macrophage in mice liver. (M) ELISA analysis measures the levels of TGFBI in eyeball blood and liver tissue from mice. Data are presented as mean ± SD, unpaired two-tailed Student’s t test. ∗ p <0.05, ∗∗ p <0.01, ∗∗∗ p <0.001, ∗∗∗∗ p <0.0001. BMDM, bone marrow-derived macrophages; ICC, intrahepatic cholangiocarcinoma; IHC, immunohistochemistry; QPCR, quantitative PCR; TAF15, TATA-binding protein-associated factor 15; TGFBI, transforming growth factor-beta induced.
Article Snippet: The transforming growth factor-beta induced (TGFBI) ELISA test kit was purchased from CUSABIO (CSB-EL023450MO, CSB-E16665h, Wuhan, China).
