PMA 분화 THP-1 대식세포의 LPS 및 ATP 유도 사멸 및 그 검증

Executive Industry Relevance

Discriminating between pyroptosis, apoptosis, and necroptosis in PMA-differentiated THP-1 macrophages following LPS and ATP stimulation is critical for target validation and mechanistic de-risking in inflammation research. Quantitative flow cytometry and ultrastructural analysis enable predictive confidence in cell death pathway assignment, supporting robust early discovery decisions. This workflow informs portfolio triage by clarifying the biological consequences of inflammatory triggers in human macrophage models.
