Proteomic studies are essential for identifying the proteins that pathogens use to infect hosts and evade the immune system. For instance, the spike protein of SARS-CoV-2 has been a primary target for vaccine development. Proteomics can also help identify biomarkers for disease diagnosis and prognosis, and reveal potential targets for new therapeutics. Additionally, understanding the host's protein response to infection can provide insights into disease mechanisms and potential interventions.
