The mean fluorescence intensity (MFI) of IFNs related proteins in HIV-negative controls (HC), acute HIV-1-infected (AHI) patients and chronic HIV-1-infected (CHI) patients. The flow cytometry was used to evaluate the protein levels. All expression analysis was performed by flow cytometry using BD FACSCanto™ II with Diva software. The results are shown mean ± standard deviation, the asterisks denote p < 0.01
