Antibodies that protect against group A strep infections

Protective antibody in streptococcal infection models

NIH-funded research New York Medical College · NIH-10999401

Researchers are looking for antibodies that stop group A streptococcus and testing whether antibodies from adults could protect children from infection.

What this research studies

The team compares blood taken from children just before they get a strep infection with blood from adults to find antibody gaps in kids. They will purify the relevant antibodies from adults and give them to mice that are vulnerable to infection to see which antibodies block low-dose, realistic exposures. Successful antibody targets will be combined into candidate multicomponent vaccines for broader protection against many strep strains. The work aims to pinpoint the specific bacterial parts that antibodies should target to prevent disease.

Who could benefit from this research

Good fit: Ideal participants would include young children at risk for group A strep and healthy adults willing to donate blood samples for antibody analysis.

Not a fit: People with conditions unrelated to group A streptococcal infection or those seeking immediate treatment for an active infection would not directly benefit from this preclinical work.

Why it matters

Potential benefit: Could lead to vaccines or antibody-based protections that prevent group A strep infections in children worldwide.

How similar studies have performed: Previous animal and laboratory studies show antibodies can protect against strep and some vaccine candidates have promise, but a universally protective multicomponent GAS vaccine has not yet been achieved.
