    Tumor Necrosis Factor-α-Induced Protein 8-like 2 Fosters Tumor-Associated Microbiota to Promote the Development of Colorectal Cancer

    Scientists suggested that hematopoietic TNF-α-induced protein 8-like 2 (TIPE2) regulated intestinal anti-tumor immunity by regulation of gut microbiota. TIPE2 may represent a new therapeutic target for treating colorectal cancer.
