We next analyzed the expression of CD19, CD5, and CD1d in liver tissues obtained from mice with MASLD, HCC/CaMIN and HCC/NRASG12V/p19Arf-/- using immunohistochemistry (IHC) and immunofluorescence (IF) (Fig. 7 and Fig. S6). Here, CD19 is linked to metabolic dysfunction-associated steatotic liver disease.
