Methodological advances in necroptosis research: from challenges to solutions.

Necroptosis is currently attracting the attention of the scientific community for its broad implications in inflammatory diseases and cancer. However, detecting ongoing necroptosis under both experimental and clinical disease conditions remains challenging. The technical barrier lies in four aspects, namely tissue sampling, real-time monitoring, specific markers, and distinction between different types of cell death. In this review, we presented the latest methodological advances for necroptosis identification. The advances highlighted the multi-parameter flow cytometry, sA5-YFP tool, radiolabeled Annexin V/Duramycin, Gallium-68-labeled IRDye800CW contrast agent, and SMART platform . We also discussed the up-to-date research models in studying necroptosis, particularly the mice models for manipulating and monitoring necroptosis. Based on these recent advances, this review aims to provide some advice on current necroptosis techniques and approaches.
