It identifies distinct immune cell states by computing cell surface biomarker polarity from immunofluorescence imaging data and has shown potential for predicting patient survival outcomes, revolutionizing precision medicine. **The Challenge of Protein Localization** Accurately analyzing and quantifying protein localization within cells, especially in tumor microenvironments, presents a significant challenge. Current methods tend to aggregate protein expressions, resulting in an inability to differentiate cells based on their subcellular protein expression patterns. **The Innovation: PEPSI** PEPSI offers a novel methodology for measuring subcellular protein localization. By computing the polarity of cell surface biomarkers from immunofluorescence imaging data, PEPSI classifies cells into subtypes based on their surface protein marker polarity. **Application and Insights** Applied to large-scale datasets and patient samples, PEPSI has provided insightful revelations, particularly in characterizing the functional state of immune cells within tumors. Incorporating polarity-defined cell subtypes into deep learning models has resulted in a notable improvement in predicting patient survival outcomes. **Implications and Future Potential** PEPSI stands as a significant advancement in spatial proteomics, offering new insights into the functional conditions of immune cells in the tumor microenvironment. This methodology could revolutionize researchers’ understanding of patient responses to treatments and disease prognostics, marking a significant step forward in precision medicine. 🤖 **Evolve Your Company with AI: Practical Solutions and Value** **Unlocking Automation Opportunities** Identify key customer interaction points benefiting from AI automation and define measurable impacts on business outcomes. **Selecting AI Solutions** Choose tools aligning with your needs and providing customization, implementing them gradually and expanding usage judiciously. **Spotlight on an AI Sales Bot** Explore the AI Sales Bot from itinai.com/aisalesbot designed to automate customer engagement 24/7 across all customer journey stages.
