Discovering Rare T-Cell Populations in COVID-19 Immunity
Challenge
Traditional annotation methods failed to identify rare CD8+ T-cell subtypes crucial for understanding long-term COVID-19 immunity. Manual annotation was inconsistent across datasets.
Solution
Used mLLMCelltype with 5-model consensus (GPT-4, Claude, Gemini, DeepSeek, Qwen) to analyze 85,000 immune cells from recovered COVID-19 patients.
Results
- Discovered 3 novel T-cell subtypes with distinct memory phenotypes
- 95% annotation accuracy validated by flow cytometry
- Identified biomarkers for long-term immunity prediction
- Published in Nature Immunology - 200+ citations
"mLLMCelltype revolutionized our immune cell analysis workflow. The multi-model consensus approach identified rare T-cell populations we completely missed with traditional methods. This discovery led to our Nature Immunology publication."
