Onyx
Onyx is a research collective based in Berkeley, California. We run research studies that follow how people’s immune systems change over time with disease, treatment, and aging. Scientists use this research to understand why a treatment helps one person and not another, identify meaningful differences between patients, and develop more precise medicines.
