Immunostimulation via Induction of Humoral and Cellular Immune Responses to SARS-CoV-2 Spike and Nucleocapsid Proteins (None)

Target
None
Molecular classification
Immunological target, Viral antigen, Spike protein, Nucleocapsid protein
01

Overview

This immunostimulant target refers to agents or mechanisms that enhance the body's immune response—both humoral (antibody-mediated) and cellular (T-cell mediated)—specifically against the spike (S) and nucleocapsid (N) proteins of SARS-CoV-2, the virus responsible for COVID-19. These viral proteins are key antigens recognized by the immune system during infection or vaccination. Vaccines leveraging these targets aim to induce broad protective immunity. Therapeutic monoclonal antibodies often target conserved regions within the spike RBD. The strength of induced immune responses correlates with protection from severe disease; however, excessive stimulation may contribute to immunopathology if not properly regulated.
