Figure 2From: Comparative analyses of host responses upon infection with moderately virulent Classical swine fever virus in domestic pigs and wild boarB-cell related responses upon infection. Blood lymphocytes were immune-stained to determine the frequency of different B cell subpopulations by FACS analysis: conventional B cells: CD3-CD2 + CD21+; activated B cells upon antigen contact: CD3-CD2-CD21+ and antibody forming and/or memory B cells: CD3-CD2 + CD21-. Filled symbols represent data from infected animals in comparison to uninfected controls (open symbols).Back to article page
