The expression of TSLP when stimulated with EGF in U251 cell line and GBM-b cells suggests a potential contribution of GBM to the immunomodulation of the tumor microenvironment, through the production of TSLP, in line with previous reports in different tumors (Corren and Ziegler 2019) (Zhang et al. 2017; Protti and De Monte 2020). The gene discussed is EGF; the disease is glioblastoma.
