CD4 and cancer: Furthermore, similar to the cancer cachexia-model mice, the percentages of CD8+ T cells, CD4+ T cells (Fig. 6I-K) and NK cells (Fig. 6L-M) were significantly decreased in the spleen of LPS-injected mice (Unpaired t-test, *p < 0.05, **p < 0.01, *** p < 0.001 vs. saline-injected group).
