| Core Tip |
The presence of intratumoral bacteria was identified in a subset of hepatocellular carcinoma (HCC) cases. Gram-negative bacteria and their associated endotoxins were found to promote the recruitment of monocytic myeloid-derived suppressor cells through activation of the TLR4/CCL2/CCR2 signaling axis. This process may contribute to the establishment of an immunosuppressive tumor microenvironment, thereby influencing both tumor progression and clinical prognosis in HCC. Collectively, our findings identified lipopolysaccharide (LPS) as a potential prognostic biomarker for HCC and indicated that therapeutic targeting of the LPS/TLR4/CCL2/CCR2/monocytic myeloid-derived suppressor cell axis may represent a promising strategy for future HCC treatment. |
