In human prostatecarcinoma, high levels of nitrotyrosine in T cells due to the action ofperoxynitrite, makes them unresponsive to tumor antigen [169].Direct contact of T cells with MDSCs leads to the nitration of T cellreceptor (TCR) and CD8 molecules making them unresponsive tospeciï¬c antigen stimuli [170,171].
