Abstract:
Rheumatic fever (RF) and rheumatic heart disease (RHD) are postinfectious complications of an infection (or repeated infection) with the Gram-positive bacterium, Streptococcus pyogenes (also known as group A streptococcus, GAS). RF and RHD are global problems and affect many indigenous populations of developed countries and many developing countries. However, RF and RHD are only part of a larger spectrum of diseases caused by this organism. The development of a vaccine against GAS has primarily targeted the abundant cell-surface protein called the M-protein. This review focuses on different M-protein-based-subunit vaccine approaches and the different delivery technologies used to administer these vaccine candidates in preclinical studies.
Insights
Developing a vaccine against Streptococcus pyogenes (group A streptococcus, GAS) is crucial for preventing rheumatic fever and rheumatic heart disease. This review explores M-protein-based vaccines and delivery methods in preclinical research.
Area of Science:
- * Infectious Diseases
- * Vaccinology
- * Microbiology
Background:
- * Rheumatic fever (RF) and rheumatic heart disease (RHD) are serious postinfectious sequelae of Streptococcus pyogenes (group A Streptococcus, GAS) infection.
- * These diseases disproportionately affect indigenous populations globally, representing a significant public health challenge.
- * GAS causes a spectrum of diseases beyond RF and RHD.
Purpose of the Study:
- * To review M-protein-based subunit vaccine strategies against GAS.
- * To examine various delivery technologies employed in preclinical vaccine development for GAS.
- * To assess the current landscape of vaccine candidates targeting M-protein.
Main Methods:
- * Comprehensive literature review of preclinical studies on GAS M-protein vaccines.
- * Analysis of different subunit vaccine formulations and antigen presentation methods.
- * Evaluation of diverse vaccine delivery systems and their efficacy in animal models.
Main Results:
- * M-protein is a primary target for GAS vaccine development due to its abundance and immunogenicity.
- * Various subunit vaccine approaches, including recombinant proteins and conjugates, have shown promise.
- * Different delivery technologies, such as nanoparticles and viral vectors, are being investigated for enhanced immunogenicity.
Conclusions:
- * M-protein-based subunit vaccines represent a promising strategy to prevent GAS infections and their sequelae.
- * Optimizing vaccine delivery systems is critical for achieving protective immunity against GAS.
- * Further preclinical research is essential to advance GAS vaccine candidates towards clinical trials.
