A plausible neuropathologic link between Zika virus and CNS anomalies is supported by research showing viral neurotropism in intraperitoneally infected mice (online Technical Appendix reference 52) and progression of disease in directly infected mouse brains (online Technical Appendix reference 53). One hypothesis for Zika virus’s role in CNS malformations pertains to the virus’s hijacking of autophagy during viral replication (online Technical Appendix reference 54). Some cellular proteins have a dual role in autophagy and centrosome stability; a normal number of centrosomes is important for brain development (online Technical Appendix reference 54). An increase in centrosomes in mice has been shown to result in microcephaly (online Technical Appendix reference 54). Therefore, Zika virus’s interference in autophagy has been hypothesized to lead to an increase in centrosome number and microcephaly; this potential role in malformations merits further investigation.
