Scientists probe immune secrets of eye allergies to improve treatments

This study looks at how certain immune cells (regulatory T cells and Th2 cells) work in people with allergic conjunctivitis, both those who have received desensitization therapy and those who have not, compared to healthy individuals. Researchers will collect blood and tear samples from 60 participants aged 5 to 30 to measure cell activity and related molecules. The goal is to find biological markers that could help tailor better treatments for this common eye condition.
