Abstract: The invention relates to the diagnosis of a SARS-associated coronavirus, such as a SARS CoV-2 infection and SARS-CoV infection, using the SARS-CoV and SARS-CoV-2 nucleocapsid proteins and antibodies binding to these proteins. The invention encompasses reagents, methods and kits for the detection of a SARS-associated coronavirus.

Abstract: The invention is in the domain of delivery of molecules to brain cells across the blood-brain barrier. The invention relates to a novel polypeptide-based carrier that allows the efficient delivery of an effector peptide, to neuron cells across the blood-brain barrier, and to methods for the production and testing of such carrier, including a model for testing the capacity of such molecule to cross the blood-brain barrier and/or the toxicity of molecules on the blood brain barrier and/or the capacity of molecules that have crossed to target human brain cells (e/g. neurons, astrocytes and microglial cells).
