The inventors have investigated the use of an attenuated B. pertussis strain as a live vehicle for the expression of heterologous antigens (e. g. SARS-CoV-2 N-protein) through the auto-transporter SphB1 secretion machinery. The passenger domain of Sph1 was replaced by N- protein in an expression cassette containing the pertactin signal peptide coding region and promoter region. The chimeric protein was successfully produced and secreted to the extracellular medium. Nasal administration of the live recombinant strains triggered a specific systemic cell-mediated response against N-protein. These results support the use of live attenuated B. pertussis strains as a potential vaccine platform for heterologous antigen delivery.

A use of a S protein or P4HB protein as a target in preparation of a drug for prevention or treatment of coagulopathy associated with SARS-CoV-2 infection. The S protein is the spike protein of SARS-CoV-2 virus, and the P4HB protein is human protein disulfide isomerase. By means of integrated proteomic and bioinformatic study on SARS-CoV-2 interaction networks in endothelial cells, pulmonary cells, and bronchial cells, the S protein is determined as a key contributor to the procoagulant characteristics of viruses, and the S protein plays a critical role in inducing endothelial cell dysfunction. The S protein directly interacts with P4HB by means of an RBM region thereof, and promotes the secretion of P4HB by means of a lysosomal secretion pathway, thereby promoting thrombosis both in vitro and in a mouse model. Genetic or pharmacological targeting of S-P4HB axis can alleviate coagulopathy in a mouse model. The level of P4HB and disulfide bonds of target proteins thereof are significantly altered in the plasma and leukocytes of COVID-19 patients and are closely associated with the disease severity and coagulation correlation of these patients.
