Effect of interference peptides on the A1-A2AHet structure determined by proximity ligation assay (PLA) confocal microscopy images (superimposed sections) in which A1-A2AHets appear as red spots. HEK-293 T cells expressing A1R and A2AR were treated for 4 h with medium (control) or 4 μM of indicated TM peptides of A2AR; cell nuclei were stained with DAPI (blue); scale bars: 10 μm
