Scientists investigate hidden immune cells behind CVID complications

NCT ID NCT07255157

First seen Dec 03, 2025 · Last updated Apr 23, 2026 · Updated 25 times

Summary

This study looks at a type of immune cell called peripheral helper T-cells (Tph) in people with Common Variable Immunodeficiency (CVID). The goal is to see if these cells cause non-infectious complications by helping other immune cells produce antibodies. Researchers will study blood samples from 60 adults with CVID to understand this process better. This is an observational study, not a treatment trial.
