Experimental Models of SARS-COV-2 Infection in the Central Nervous System

Area of Science:

• Neurology
• Virology
• Infectious Diseases

Background:

• Coronavirus disease 2019 (COVID-19) presents significant global health challenges.
• Neurological complications in COVID-19 patients suggest potential invasion of the nervous system by SARS-CoV-2.
• The long-term effects of SARS-CoV-2 neurotropism on the central nervous system (CNS) remain largely unknown.

Purpose of the Study:

• To review current knowledge on the mechanisms of neuronal invasion by SARS-CoV-2.
• To describe the effects of SARS-CoV-2 infection on the nervous system based on experimental models.
• To inform the development of therapies for mitigating neurological damage.

Main Methods:

• Review of experimental models investigating SARS-CoV-2 neurotropism.
• Analysis of existing data on neurological manifestations of COVID-19.
• Synthesis of information on viral mechanisms of neuronal invasion.

Main Results:

• Evidence suggests SARS-CoV-2 can invade the nervous system.
• Pathophysiological processes underlying neurological impact are not fully understood.
• Experimental data on long-term CNS effects are limited.

Conclusions:

• Understanding SARS-CoV-2 neurotropism is crucial for developing targeted therapies.
• Long-term monitoring and effective treatments can reduce symptom severity and improve patient quality of life.
• Further research is essential to elucidate the full impact of SARS-CoV-2 on the human nervous system.
