Summary: SARS-CoV-2 infection can lead to neuroinflammation and neurological symptoms, with the structural protein S1 potentially inducing these processes independently of viral infection. Experimental findings show that S1 causes various physiological and behavioral changes in rats and microglial cells in vitro, as well as alterations in neuroimmune gene and protein expression, suggesting a role in neuroinflammatory processes via receptor engagement.

Summary: The Omicron variant of SARS-CoV-2 has a higher affinity for ACE2 and can evade neutralizing antibodies more effectively compared to the Delta variant. A third dose of mRNA vaccine can provide enhanced protection. Omicron has lower replication in lung and gut cells and less efficiently cleaves its spike protein compared to Delta.

Summary: Anosmia, the loss of smell, is a common symptom of COVID-19, but it is caused by the virus attacking sustentacular cells in the olfactory mucosa rather than infecting olfactory sensory neurons. This suggests that SARS-CoV-2 is not a neurotropic virus.

Summary: The study demonstrates the presence of SARS-CoV-2 in the nasopharynx and brain, suggesting the virus may enter the CNS through the olfactory mucosa. The virus utilizes the neural-mucosal interface in the olfactory mucosa to penetrate the nervous system, affecting various neuroanatomical areas, including the primary respiratory and cardiovascular control center.

Summary: The study demonstrates that the SARS-CoV-2 spike 1 protein can cross the mouse blood-brain barrier and be taken up by both the brain and peripheral tissues. Intravenous injection results in higher levels of protein uptake in the brain compared to intranasal administration. Genetic factors and sex have varying effects on the uptake of the spike protein in different tissues.

Summary: Recent studies suggest that the novel coronavirus may infect the brain through the olfactory nerve, causing loss of smell and taste. However, the current evidence for infection of olfactory neurons leading to brain infection is inconclusive, with conflicting results from animal and human studies. More research is needed to determine the exact mechanisms and routes of brain infection by SARS-CoV-2.

Summary: Many patients with SARS-CoV-2 infection exhibit neurological signs and symptoms, but autopsy results show that most brains have low levels of detectable virus and it does not correlate with the histopathological alterations.

Summary: This study investigated the neurotropism of SARS-CoV-2 in a non-human primate model and found that the virus primarily invades the central nervous system via the olfactory bulb, then quickly spreads to different functional regions, possibly inducing inflammation. This experimental evidence provides important insights into the CNS-related pathogenesis of SARS-CoV-2.

Summary: The COVID-19 pandemic is associated with significant morbidity and mortality. Experimental studies in animals infected with SARS-CoV-2 have revealed severe lung and brain damage, as well as early onset anosmia in mice. Excitingly, infusion of convalescent plasma from recovered patients has shown to protect against lethal disease, though it does not prevent anosmia.
