Understanding how immunity to one virus affects others

The paradox of flavivirus antigenic non-reciprocity

NIH-funded research University of Wisconsin-Madison · NIH-11143662

This research explores how having immunity to one type of virus, like dengue, can change how your body responds to a different, but related, virus such as Zika.

What this research studies

This project looks into how your body's immune response to one virus, like dengue, can affect how you react to a different, but related, virus such as Zika. Sometimes, immunity to one virus might protect you from another, but other times it could actually make a future infection worse. Researchers are particularly interested in why this protection or enhancement isn't always a two-way street, meaning immunity to virus A might help against virus B, but immunity to virus B might not help against virus A. They believe that the specific parts of the virus your antibodies recognize, and how well those antibodies work, play a big role in these complex interactions. This work aims to understand these differences to better predict and manage future flavivirus infections.

Who could benefit from this research

Good fit: This research is relevant to individuals who have been exposed to or infected with flaviviruses like dengue or Zika, or those living in areas where these viruses are common.

Not a fit: Patients not affected by flaviviruses or related viral infections would not directly benefit from this specific research.

Why it matters

Potential benefit: Understanding these complex immune interactions could lead to better vaccines and treatments for diseases like dengue and Zika, helping to prevent severe illness.

How similar studies have performed: Previous studies have observed these complex immune responses in human populations, but this research aims to uncover the specific reasons behind these non-reciprocal effects.
