Interestingly, the enrichment of CD8+ T cells and much more aggregation of CD4+ T cells, CD49b+ NK cells were observed in CRC mice accepted with FMT, as well as reduced population of Foxp3+ Treg cells, F4/80+ macrophages, indicating the augmentation of anti-cancer efficacy (Figure 3). The gene discussed is FOXP3; the disease is colorectal carcinoma.
