Background: The Niemann Pick C1 (NPC1) protein is an intracellular cholesterol transporter located in the late endosome/lysosome (LE/Ly) that is involved in the mobilization of endocytosed cholesterol. Loss-of-function mutations in the NPC1 gene lead to the accumulation of cholesterol and sphingolipids in LE/Ly, resulting in severe fatal NPC1 disease. Cellular alterations associated with NPC1 inactivation affect both the integrity of lipid rafts and the endocytic pathway.

SARS-CoV-2 pandemic clearly demonstrated the lack of preparation against novel and emerging viral diseases. This prompted an enormous effort to identify antivirals to curb viral spread and counteract future pandemics. Ribosome Inactivating Proteins (RIPs) and Ribotoxin-Like Proteins (RL-Ps) are toxin enzymes isolated from edible plants and mushrooms, both able to inactivate protein biosynthesis.

After over one year of evolution, through billions of infections in humans, SARS-CoV-2 has evolved into a score of slightly divergent lineages. A few different amino acids in the spike proteins of these lineages can hamper both natural immunity against reinfection, and vaccine efficacy. In this study, the in vitro neutralizing potency of sera from convalescent COVID-19 patients and vaccinated subjects was analyzed against six different SARS-CoV-2 lineages, including the latest B.
