Protein quantitation was made using iTRAQ as performed on cell lysates of BMM from three separate experiments.
These experiments compared HIV-1/VSV infected murine BMM that were cocultured with murine Treg (117 label) to HIV-1/VSV infected murine BMM cultured alone (115 label).
P-value after Benjamini and Hochberg FDR adjustment.
