Paraneoplastic neurologic diseases (PND) involving immune responses directed
toward intracellular antigens are poorly understood. Here, we examine immunity to
the PND antigen Nova2, which is expressed exclusively in central nervous system
(CNS) neurons. We hypothesized that ectopic expression of neuronal antigen in the
periphery could incite PND. In our C57BL/6 mouse model, CNS antigen expression
limits antigen-specific CD4+ and CD8+ T-cell expansion. Chimera experiments
demonstrate that this tolerance is mediated by antigen expression in
nonhematopoietic cells. CNS antigen expression does not limit tumor rejection by
adoptively transferred transgenic T cells but does limit the generation of a
memory population that can be expanded upon secondary challenge in vivo. Despite
mediating cancer rejection, adoptively transferred transgenic T cells do not lead
to paraneoplastic neuronal targeting. Preliminary experiments suggest an
additional requirement for humoral activation to induce CNS autoimmunity. This
work provides evidence that the requirements for cancer immunity and neuronal
autoimmunity are uncoupled. Since humoral immunity was not required for tumor
rejection, B-cell targeting therapy, such as rituximab, may be a rational
treatment option for PND that does not hamper tumor immunity.
