This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers are studying special immune cells called natural killer cells in people with severe asthma. These cells normally help fight off viruses like colds, but scientists don't yet understand how they behave differently in people with severe asthma—especially when viruses trigger asthma flare-ups. By comparing these cells in people with different types of asthma and in healthy people, researchers hope to find biological markers that could help doctors better diagnose severe asthma and predict when flare-ups might happen.
About 10% of people with asthma don't respond well to standard treatments and continue to suffer symptoms. Scientists believe understanding how immune cells work differently in these patients could lead to better ways to diagnose severe asthma and prevent viral infections from triggering dangerous flare-ups.

Participants will donate blood samples that researchers will study in the laboratory to examine natural killer cells. Healthy volunteers and people with different types of asthma (controlled, uncontrolled without a flare-up, and uncontrolled with an active flare-up) are all needed. Depending on which group you join, you may be asked to visit an expert asthma center where specialists will confirm your asthma diagnosis or health status, collect blood samples, and discuss how your asthma has been recently.
