Immunotherapy with dendritic cell based vaccines for treating glioma has become one attractive approach. To access the efficiency of DC vaccine, it is necessary to monitor the distribution of DCs in the CNS or lymphoid organs. Our goal is to target molecules, which are involved in regulating DCs within the glioma context. In this study we found that deficiency of ERK1 result in tumor regression. 19F/1H MRI monitored the migration of DCs and found that ERK1 can regulate DC migration.
