Basic Immunology Research Underlies Medical Treatments

Here are some examples of how the knowledge gained from basic research translates into the development of vaccines and immunotherapies:

Identify specific antigens and other targets: Scientists study the structure and function of pathogens to pinpoint components that can elicit immune responses. This knowledge is crucial for designing vaccines that stimulate protective immunity.

Design vaccines that mimic natural infections: Vaccines may contain weakened or inactivated forms of pathogens, fragments of pathogens, or genetically engineered components. These formulations stimulate the immune system to produce a protective response, including the production of antibodies and memory cells.

Design mRNA-based vaccines: Understanding 1) the differences in RNA nucleotide modifications between different organisms and 2) how mRNA is translated into proteins within cells has paved the way for the development of innovative vaccines like those against COVID-19. These vaccines teach cells to produce specific viral proteins, eliciting an immune response without using live viruses.

Development of adjuvants: Adjuvants are substances added to vaccines to enhance the immune response. Researchers study how adjuvants modulate immune reactions, ensuring that vaccines elicit robust and long-lasting protection. The formulation of vaccines is optimized based on knowledge about the immune system’s ability to recognize and respond to specific stimuli.

Immunotherapies: Often, the immune system is dysregulated in diseases like cancer and autoimmune disorders. Understanding the details of the dysregulations can form the basis for developing immunotherapies that modulate immune responses. For example, immune checkpoint blockades (also know as immune checkpoint inhibitors) and CAR-T cell therapies leverage insights into immune checkpoints and T cell engineering, respectively, to enhance the body’s ability to recognize and eliminate cancer cells.

Monoclonal antibodies: Specific antibodies that can neutralize pathogens or regulate immune responses. This motivates researchers to produce monoclonal antibodies for therapeutic purposes. Monoclonal antibodies are utilized in the treatment of various diseases, including infectious diseases and autoimmune conditions.

Personalized medicine: There is heterogeneity of immune responses among individuals. This understanding supports the development of personalized immunotherapies tailored to an individual’s immune profile. Precision medicine approaches leverage knowledge about genetic, molecular, and immunological factors to optimize treatment outcomes.
