How obesity affects immune responses to influenza virus infections

Official title: Impact of obesity on antiviral NK cell function and immune crosstalk with respiratory epithelial cells during influenza virus infection

Funded at St. Jude Children's Research Hospital · NIH-10903473 · Data updated 2026-11-12

This study is looking at how being overweight affects your immune system, especially how certain immune cells work when you get the flu, to help explain why people with obesity might get sicker from respiratory infections.

Who could benefit from this research

Could help

Ideal candidates for this research are adults with obesity, defined as having a BMI greater than 30.

Less likely to help

Patients who are not obese or do not have respiratory infections may not benefit from this research.

What this research studies

This research investigates the impact of obesity on the function of natural killer (NK) cells during influenza virus infections. It aims to understand how obesity, characterized by a Body Mass Index (BMI) over 30, alters the immune response, particularly the interaction between NK cells and respiratory epithelial cells. By examining these mechanisms, the study seeks to uncover why individuals with obesity are more susceptible to severe respiratory infections. The research will involve laboratory experiments to analyze NK cell behavior in the context of viral infections.

Why it matters

Potential benefit: If successful, this research could lead to improved treatments and preventive strategies for respiratory infections in obese individuals.

How similar studies have gone: Previous research has shown that obesity can negatively impact immune responses in other contexts, suggesting that this investigation may yield important insights.
