Figure 2From: CTLA4 is expressed on mature dendritic cells derived from human monocytes and influences their maturation and antigen presentationCTLA4 mRNA was detected in mature DCs but not immature DCs, as determined by RT-PCR. The cells were purified by sorting with flow cytometry. iDC: immature DCs; mDC: mature DCs; M: molecular ladder. A representative experiment is shown.Back to article page
