Immune cells enhance Zika virus-mediated neurologic dysfunction in brain of mice with humanized immune systems
Zika virus (ZIKV) can generate a number of neurological dysfunctions in infected humans. Here, we tested the potential of human immune cells to protect against ZIKV infection in genetically humanized MISTRG mice. FACS analysis showed robust reconstitution of the mouse spleen with human T cells. Peripheral ZIKV inoculation resulted in infection within the brains of MISTRG mice. Mice that were reconstituted with human peripheral blood mononuclear cells (PBMC) showed a more rapid lethal response to ZIKV than the control mice lacking these immune cells. Immunocytochemical analysis of T cell markers CD3, CD45, or CD8 showed strong T cell presence in the brain, together with robust infection by ZIKV particularly in the excitatory pyramidal and granule neurons of the hippocampus. Infection was also found in cortex, striatum, the dopamine neurons of the substantia nigra, and other brain loci. Infection was considerably less in other regions such as the septum and hypothalamus. These data support the perspective that, rather than exerting a protective function, T cells may underlie some ZIKV-mediated neuropathology in the brain.
期刊介绍:
Developmental Neurobiology (previously the Journal of Neurobiology ) publishes original research articles on development, regeneration, repair and plasticity of the nervous system and on the ontogeny of behavior. High quality contributions in these areas are solicited, with an emphasis on experimental as opposed to purely descriptive work. The Journal also will consider manuscripts reporting novel approaches and techniques for the study of the development of the nervous system as well as occasional special issues on topics of significant current interest. We welcome suggestions on possible topics from our readers.
