E-mail: Rodriguez@mayo.edu <h3>SPECIFIC AIMS</h3> We developed an MRI technique to image immune cell location and homing in vivo to the central nervous system (CNS). Superparamagnetic antibodies specific for cell surface markers allowed imaging of CD4+ T cells, CD8+ T cells, and Mac1+ cells in the CNS of mice infected with Theiler’s murine encephalomyelitis virus (TMEV) and in mice with experimental autoimmune encephalomyelitis (EAE). <h3>PRINCIPAL FINDINGS</h3> <h3>1. In vivo MRI detects immune cells in viral and autoimmune models of multiple sclerosis</h3> We evaluated the efficacy of a new method to image immune cells in the CNS of animals chronically infected with TMEV. Superparamagnetic anti-CD4, anti-CD8, anti-Mac1, and irrelevant control anti-human CD19 antibodies
