Abstract
Coronavirus disease 2019 (COVID-19) interacts with the nervous system directly and indirectly by affecting the activation of the immune system. Guillain–Barré syndrome (GBS) is triggered by an inappropriate immune system activation that overlaps with the neurotoxic mechanism of an invading pathogen. Here, we discuss the complexity of an abnormal immune system response leading to the generation of autoimmunity in the setting of acute viral infection. A 67-year-old male patient with COVID-19 developed a sensory motor acute polyneuropathy with respiratory failure. Several serum inflammatory and neurodegeneration markers were collected during hospital days 1, 3, 8, and 67 and compared to healthy individuals. Neural cell adhesion molecule 1 (NCAM-1) and neurofilament light chain (NfL) values were highly variable when compared to healthy individuals, but not to the reference COVID-19 group. We focused our attention on NCAM-1 as a possible target for antibodies directed at COVID-19 in silico.Keywords
