In the “cold” tumor LGG, TASL expression was significantly and positively correlated with the content of immunosuppressive Th2 cells (R = 0.350, P < 0.001) and M2 macrophages (R = 0.280, P < 0.001), and less correlated with the content of immunostimulatory Th1 cells (R = 0.170, P < 0.001, Fig. 7A, B). Here, TASL is linked to neoplasm.
