TLR2 and neoplasm: The tumor-bearing mice were monitored by living imaging, and the results were presented in Fig. 4B. Not surprisingly, the statistical outcomes demonstrated that TLR2 pep-orid-liposome exhibited the best efficacy in reducing tumor burden, as evidenced by the total flux (summed up fluorescence of dorsal and ventral) among the 5 groups (Fig. 4C), with a significant difference observed compared to the other treatment groups.
