IN VITRO METHOD FOR MODIFYING THE DEPLETION PROFILE OF TREG CELLS PRESENT IN A TOTAL SPLENOCYTE POPULATION OF A BIOLOGICAL SAMPLE BY MEANS OF THE ISOLATION, CULTURING AND EXPOSURE THEREOF TO AN ATP AND POLYMIXIN B MEDIUM
In vitro method to modify the deplexion profile of Treg Cells present in a total splenocyte population of a biological sample comprising isolating, cultivating and submitting the splenocyte at a ATP medium and polymyx B, where the splenocytes at concentrations of Polymyxin B in the range 0.1 μg/ml to 100 μg/ml, and combined use of Polymyxin B and ATP to prepare a medicament useful in the treatment tumor or cancer mammals, where cancer is melamine.
