NRP1 and infection: Other receptors and co-receptors could also be involved in viral entry, such as CD147 glycoproteins, which are ubiquitous and highly expressed in proximal tubule cells, and Neuropilin-1 (NRP1), which is expressed in the olfactory epithelium, and could facilitate infection with SARS-CoV-2 and provide a potential pathway for the viral entry in the nervous system [48].
