TICK tock. Your Immune clock is ticking! -Immune Age- @OmniscopeAI is launching a suite of Immune Tracking products at #MWC2025. -Immune Age- leverages T cells as a living sensors to sense and memorize systemic challenges. Pathogen exposure, for instance, triggers an immune response that leaves a lasting imprint on the T cell repertoire. However, we found that the signals encoded in T cell receptor (#TCR) sequences extend far beyond infections. They carry quantifiable insights into stress, internal and external load, and, ultimately, biological aging. @OmniscopeAI, together with @FCBarcelona_es, now applies the potential of T cell sequencing as a Diagnostic tool to define Health, to optimize Performance and to avoid Injuries. Our T Cell Clock is a dynamic measure to quantify the accumulation of a player's load and the success of targeted interventions. No doubt, our -Immune Age- application will go beyond the area of sports, to better define health and to extend healthy aging (#Healthspan). Our T cell sensor approach provides a new Biomarker strategy to quantify #BiologicalAge, complementing the more static Methylation clocks (@EricTopol : erictopol.substack.com/p/ste…). Excited to see -Immune Age- to be applied in additional health intervention studies. Please reach out to collaborate! #HealthyAging #Longevity

👏Our congratulations to the #ICREAresearcher (@hoheyn @cnag_eu) co-founder of @OmniscopeAI, on the development of such advances on this platform that make information on the immune system accessible and interactive.
Ladies and gentlemen – Full #ImmuneGPT integration is live 🚀 Talk to your immune system🩸 At #JPM, @Omniscope launched a major milestone: ImmuneGPT is now fully integrated into #osLifetime. You think the immune system is too complex? That we need more data and better models to crack the immune code? Right — and wrong. You are right: Immunology is complex. You are wrong if you think that complexity should stay inaccessible. #ImmuneGPT was built to make complex biology immediately useful. And #osLifetime was built to visualize immune cells as Living Biomarkers🩸, translating deep immune signals into personalized, actionable recommendations — from lifestyle and diet to exercise, supplements, and longitudinal health tracking. What’s new — and what changes everything: 🔥 Your Cellular Avatar is now interactive With ImmuneGPT integrated, your immune system comes alive. You can now interact with your personalized cellular profile, ask questions, explore immune states, and understand how choices today shape immune health tomorrow. Yesterday, Omniscope CEO Vijay Vaswani officially launched this integration, turning advanced immune modeling into something you can actually use. This is a game changer for actionability: From immune data → understanding From understanding → ownership From ownership → a longer, healthier life 👉 Explore osLifetime here: (lnkd.in/d-KewwHY) Reach out for full access to ImmuneGPT and personalized profiles! Your immune system is already talking. Now you can finally listen — and respond.

Congrats to the team! We’re happy to have contributed to the Atlas of Human Inflammation, improving the interpretability of inflammatory signatures through inference of transcription factor activity (@8JoseLinares, @roramirezf94 and @JulioSaezRod)
Ladies and gentlemen - Our Atlas of Human Inflammation today out in @NatureMedicine 💫 Welcome on stage: The Cell as a Living Biomarker🩸 We Built an Inflammation Atlas of Circulating Immune Cells. By profiling more than 6.5 million peripheral blood mononuclear cells from 1,047 patients across 19 inflammatory and immune-mediated diseases using single-cell RNA sequencing, we generated a unified, high-resolution reference of immune cell states in human disease. Despite decades of research, our understanding of Inflammation has largely remained fragmented, studied one disease at a time and often confined to specific tissues. We set out to take a different approach: to ask whether inflammation leaves a shared, measurable fingerprint at the systems level of circulating immune cells and whether this signal could be leveraged for Diagnostics and ultimately Precision Medicine. Blood, unlike tissue biopsies, is accessible, repeatable, and scalable, making it an ideal substrate for liquid biopsy approaches. The key question was whether it also contains sufficient biological signal to capture disease-driving inflammatory mechanisms❓ Using interpretable machine learning approaches, specifically gradient boosted decision trees (GBDT) combined with SHAP explanations, we asked whether single cells, and ultimately patients, could be classified based solely on their blood immune transcriptomes. !!! Disease-associated gene expression signatures enabled accurate classification within the study cohort, reinforcing the concept that immune cells in circulation function as “Living Biomarkers”🩸 We are now working toward a diagnostic prototype that brings these concepts closer to clinical reality. Together with hospital and industry partners, we aim to develop Foundation Models of immune cell plasticity that can operate across diseases and settings, enabling patient stratification, therapy monitoring, and outcome prediction from blood alone. Our long-term vision is a future in which a simple blood draw provides a systems-level readout of immune health, guiding diagnosis and treatment across inflammatory diseases. Immune cells are already doing the sensing. The challenge and opportunity is to learn how to listen. Please find the Nature Medicine Paper here: lnkd.in/eYV7pwrN

Very happy to finally present our work! “𝘚𝘵𝘢𝘯𝘥𝘢𝘳𝘥𝘪𝘻𝘦𝘥 𝘮𝘦𝘵𝘳𝘪𝘤𝘴 𝘧𝘰𝘳 𝘢𝘴𝘴𝘦𝘴𝘴𝘮𝘦𝘯𝘵 𝘢𝘯𝘥 𝘳𝘦𝘱𝘳𝘰𝘥𝘶𝘤𝘪𝘣𝘪𝘭𝘪𝘵𝘺 𝘰𝘧 𝘪𝘮𝘢𝘨𝘪𝘯𝘨-𝘣𝘢𝘴𝘦𝘥 𝘴𝘱𝘢𝘵𝘪𝘢𝘭 𝘵𝘳𝘢𝘯𝘴𝘤𝘳𝘪𝘱𝘵𝘰𝘮𝘪𝘤𝘴 𝘥𝘢𝘵𝘢𝘴𝘦𝘵𝘴” Spatial transcriptomics promises deep insight into tissue architecture - but inconsistent data quality across labs and platforms has been a major barrier. A new study from a global consortium addresses this by releasing the Spatial Touchstone (ST): a harmonized, multi-site, multi-platform dataset using six tissue types and two widely imaging used technologies. We introduce SpatialQM, an open-source quality-control software, and a public repository, Spatial Touchstone Portal (STP), that hosts ~33M cells and ~7B transcripts. With standardized metrics for sensitivity, reproducibility, signal-to-noise, false discovery rates, and cell-type annotation, this framework gives labs a way to benchmark and compare spatial transcriptomics data reliably. This effort sets a foundation for more robust, reproducible spatial-omics research — and helps unlock cross-study comparability across institutions and platforms. I’m incredibly thankful to my amazing collaborators across the globe and an special shout out to my dear friends @DrJasPlummer and @mason_lab and their super amazing teams for literally working they brains out to make this happen.
