Transolfactory neuroinvasion by viruses threatens the human brain
Open accessAbstract
Viral neuroinvasion via the olfactory system has been investigated in a variety of virus-animal models by scientists in many fields including virologists, pathologists, and neurologists. In humans, herpes simplex virus type 1 (HSV-1), human herpesvirus 6 (HHV-6), Borna disease virus, rabies virus, and influenza A virus have been shown to take the olfactory route for neuroinvasion based on forensic and post-mortem specimens. This article briefly summarizes the anatomy, physiology, and immunology of the olfactory system and presents a battery of neurovirulent viruses that may threaten the human brain by invading through this peripheral pathway, especially focusing on two of the most intensively studied viruses--HSV-1 and influenza A virus. Viruses may insidiously invade the olfactory neural network not only to precipitate encephalitis/encephalopathy but also to promote the development of neurodegenerative and demyelinating disorders. Substantial information obtained by analyzing human specimens is required to argue for or against this hypothesis.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
