Figure 5. PRF-P induces microenvironmental changes reducing the Tregs migration toward GL261 cells.
The mRNA level for chemokine (C-C motif) ligand a. 2 and b. 22 (CCL2 and CCL22, respectively) was significantly reduced by the PRF-P treatment in GL261-Treg co-culture (n=3). c. PRF-P caused cessation of the Treg migration after pharmacological blockade of the CCL2/22 interaction with their receptors (n=3). d. Pharmacological inhibition of the soluble CD40 ligand (sCD40L) reversed the PRF-P induced reduction of the Tregs’ migration (n=3).
