Figure 1.
Proliferative responses of splenocytes from CBA mice immunized intranasally with rMVNP in saline, with LT or LTK63.
The splenocytes were stimulated in vitro with various dilutions of (A) MVNP (0.0005 to 5 µg/culture) or (B) heat inactivated MV (0.002×102 to 2×102 p.f.u/culture) or medium from mock infected cells for 4 days. Data are presented as stimulation indices (ratio of mean c.p.m of triplicate cultures with antigen to the mean c.p.m of six replicates of control cultures without antigens).
