BDKRB1 and glioblastoma: Crosstalk between mesenchymal stem cells (immunomodulatory and mobile tumor-tropic cells isolated from adipose tissue, the oral cavity, and other tissues) and glioblastoma cells has been reported in this microenvironment, and bradykinin and the bradykinin 1 receptor are involved in the interactions between these cells (cell–cell and cell fusion) [48].
