Figure 4From: A recombinant pseudotyped lentivirus expressing the envelope glycoprotein of Hantaan virus induced protective immunity in miceFrequency of antigen-specific IFN-γ- or IL-2-secreting T cells in splenocytes of mice immunized (n=4). Number of GP specific IFN-γ-secreting T cells (A) and IL-2-secreting T cells (B) were evaluated using ELISPOT assays. Results are shown as the mean value of the number of spots observed for 106 spleen cells, obtained from triplicate wells. The IFN-γ and IL-2 levels did not change significantly in the rLV-M group.Back to article page
