T cells were washed in cold PBS and resuspended in RLT buffer (Qiagen). Total RNA isolation was performed according to the manufacturer's protocol using the RNeasy MinElute Cleanup Kit (Qiagen) including an on-column DNAse digestion (Qiagen). Quality and quantity of the total RNA were assessed on a 2100 Bioanalyzer using a Nano chip (Agilent). Library preparation was performed on RNA samples with a measured RNA Integrity Number (RIN) between 8.0 and 10.0. Strand-specific libraries were generated using the TruSeq Stranded mRNA sample preparation kit (Illumina Inc.) according to manufacturer's instructions (Illumina, Part # 15031047 Rev. E). RNA libraries were prepared for sequencing using standard Illumina protocols.
