What this research studies

You would be asked to provide blood and airway samples (and in some cases lymph node fine-needle aspirates or bone marrow samples) after infection or vaccination so researchers can see which antibodies appear and when. The team will read the paired antibody genes from single B cells, measure antibodies in the blood using high-resolution mass spectrometry, and test antibody function using yeast-display methods. Both IgG and IgA antibody types and different antibody subclasses will be compared between blood and airway samples. The goal is to link specific antibody sequences with their amounts and activities in the respiratory tract versus the bloodstream.

Who could benefit from this research

Good fit: Ideal candidates are people recently infected with influenza or SARS-CoV-2 or people recently vaccinated against these viruses who can provide blood and respiratory samples and possibly undergo minor procedures like lymph node FNA or bone marrow aspiration.

Not a fit: People who are not infected or vaccinated against these respiratory viruses, or who cannot or will not provide the required samples or undergo procedures, are unlikely to benefit directly from participation.

Why it matters

Potential benefit: If successful, this work could help design better vaccines and antibody treatments by revealing which antibodies protect in the airways versus the blood.

How similar studies have performed: Related antibody-profiling studies have provided useful insights into immune responses, and this project combines established mass-spectrometry and BCR‑sequencing methods into a more comprehensive pipeline that is relatively novel.
