IVERMECTIN and LACTOFERRIN TESTIMONIAL - Oscar Nacu (Philippines, Aug.2022) IVERMECTIN and LACTOFERRIN Synergy Both compounds exhibit anticancer properties through overlapping pathways, such as inducing apoptosis (programmed cell death), modulating immune responses, and disrupting cancer cell metabolism and proliferation Lactoferrin can enhance Ivermectin’s effects by amplifying immune activation and oxidative stress, which may make cancer cells more vulnerable to IVM’s metabolic disruptions and apoptotic induction 1. Enhanced Apoptosis and Cell Death Pathways Individual Mechanisms: Lactoferrin induces apoptosis in cancer cells by damaging the cytoskeleton, activating caspases (e.g., caspase-3), upregulating pro-apoptotic proteins like BAX/BAK, and causing cell cycle arrest (e.g., G1/S or G2/M phases). It also reduces cell migration and invasion by reversing epithelial-mesenchymal transition (EMT), downregulating proteins like vimentin, SNAIL, and TWIST. Ivermectin promotes apoptosis via mitochondrial dysfunction, increasing reactive oxygen species (ROS), elevating the Bax/Bcl-2 ratio, and activating caspases 9/3. It also inhibits proliferation through cell cycle arrest and targets cancer stem cells. How They Work Together: Lactoferrin’s ability to induce oxidative stress and DNA damage complements Ivermectin’s ROS elevation and mitochondrial inhibition. This dual assault on cellular energy and redox balance could lower the threshold for apoptosis, making cancer cells more susceptible to Ivermectin’s effects 2. Immune Modulation and Tumor Microenvironment Remodeling Individual Mechanisms: Lactoferrin stimulates the adaptive immune response, reshapes the tumor microenvironment by downregulating pro-inflammatory cytokines (e.g., IL-6), and inhibits cancer progression through immunostimulatory effects. It also protects against iron disorders, depriving iron-dependent cancer cells while modulating immunity. Ivermectin has immunomodulatory properties, converting “cold” tumors (immune-deserted) to “hot” ones (immune-infiltrated) by inducing immunogenic cell death (ICD), releasing ATP and HMGB1, depleting immunosuppressive cells (e.g., MDSCs and Tregs), and enhancing CD8+ T-cell infiltration. How They Work Together: Lactoferrin’s cytokine downregulation and immune stimulation could amplify Ivermectin’s ICD and T-cell recruitment, creating a more hostile environment for cancer cells. For example, Ivermectin’s ability to boost Teff/Treg ratios pairs well with Lactoferrin’s anti-inflammatory effects, potentially enhancing overall antitumor immunity. 3. Disruption of Cancer Cell Metabolism and Proliferation Individual Mechanisms: Lactoferrin inhibits oncogenic pathways like PI3K/AKT/mTOR and Wnt, reducing proliferation and angiogenesis (e.g., downregulating VEGFR2). Ivermectin interferes with metabolic pathways, downregulating TCA cycle enzymes (e.g., IDH2, DLST), inhibiting glycolysis/oxidative phosphorylation, and limiting glutamine-derived intermediates for biosynthesis. How They Work Together: Lactoferrin’s iron sequestration starves cancer cells of essential metals for metabolic enzymes, synergizing with Ivermectin’s TCA cycle disruption to exacerbate energy shortages and biosynthetic limitations. This is particularly relevant in “glutamine-addicted” cancers like ovarian or prostate, where combined metabolic stress promotes apoptosis.

How does an embryo reliably "compute" its form - "cell by cell" - using only local interactions and mechanics, yet produce a precise global body plan? I’m excited to share our Nature Methods paper "MultiCell: geometric learning in multicellular development", presenting #AIxBiology research led by Haiqian Yang and the result of a great collaboration with Ming Guo, George Roy, Tomer Stern, Anh Nguyen and Dapeng Bi. A long-standing challenge in developmental biology is to predict how thousands of cells collectively self-organize as tissues fold, divide, and rearrange. In MultiCell, we represent a developing embryo as a dual graph that unifies two complementary views of tissue mechanics with single-cell resolution: cells as moving points (granular) and cells as a connected foam (junction network). This lets the model learn dynamics from both geometry and cell–cell connectivity. On whole-embryo 4D light-sheet movies of Drosophila gastrulation (~5,000 cells), our model predicts key cell behaviors and the timing of events, including junction loss, rearrangements, and divisions with high accuracy, at single-cell resolution. Beyond prediction, the same representation supports robust time alignment across embryos and offers interpretable activation maps that highlight the morphogenetic "drivers" of development. The broader goal is a foundation for cell-by-cell forecasting in more complex tissues, and eventually for detecting subtle dynamical signatures of disease. Kudos to the team for this inspiring collaboration with brilliant researchers to push the boundary of AI for biology! Citation: Yang, H., Roy, G., Nguyen, A.Q., Buehler, M.J., et al.

A paradigm shift is urgently needed in oncology. Conventional wisdom views radiation as a localized tool, but emerging evidence reveals its profound capacity to systemically PROMOTE cancer metastasis. In a powerful summary, Dr. Nathan Goodyear outlines the mechanisms by which radiation can inadvertently fuel the spread of cancer: - Increases Circulating Tumor Cells (CTCs): Radiation can dislodge cells from the primary tumor, releasing them into circulation as seeds for future, distant tumors. - Damages the Tumor Microenvironment: Through the "bystander effect," radiation damages healthy cells, alters epigenetics, disrupts the extracellular matrix, and modifies the local immune landscape. - Enhances Invasion & Angiogenesis: It upregulates the cancer's ability to invade surrounding tissues and stimulates angiogenesis—building the very blood vessel "highways" that facilitate spread. - Subverts the Immune System: Radiation can polarize macrophages toward the pro-tumor M2 phenotype, creating a state of chronic inflammation that allows cancer cells to evade immune detection. - Activates Dormant Sites: Via the "concomitant theory," radiation can activate distant, dormant micro-metastases, awakening sleeping giants. - Forces Mutations & Stem Cell Transformation: The genomic instability caused by radiation forces phenotypic shifts, promotes cancer stem cell transformation, and drives oncogenic metabolic shifts like the Warburg Effect. This is not to dismiss radiation's role, but to demand a more sophisticated understanding of its systemic consequences. Treatment must consider these pro-metastatic risks to truly advance patient outcomes.

Excited to share our new work on building a multimodal atlas of human skin in health and inflammatory disease — a project I’m especially proud of, bringing together AI, high-throughput genomics, and clinical science to accelerate discovery. Over the past decade, single-cell genomics has transformed how we map cells in human tissues. But a major challenge remains: can we systematically decode how cells organize into functional niches in situ — including those invisible to standard histopathology? To address this, we integrated large-scale scRNA-seq, spatial transcriptomics, histopathology, and AI-driven modeling frameworks to build an in situ atlas of human skin across health and disease. Led by Lloyd Steele, an MD/PhD student working between Haniffa Lab and my lab at Wellcome Sanger Institute and Cambridge University . Another amazing collaboration with Muzz Haniffa, the mastermind behind the work as part of Human Cell Atlas. A key part of this study is that we didn’t build everything from scratch — we leveraged and combined AI methods that actually work! and showed how they can be used together to extract biological insight at scale. We used: • scArches to build and map into a reference scRNA-seq atlas of human skin: • NicheCompass to identify and characterize spatial niches: • MINT-Flow to extract microenvironment-induced cell states and gene programs: Together, these enabled an end-to-end workflow from atlas construction to spatial mapping, niche discovery, and cell state decoding. At scale, we integrated ~5 million cells and 100+ spatial sections, enabling a systematic view of tissue organization. Using this framework, we identified 26 niches in skin, including known histopathologic structures as well as hidden disease-associated niches not visible on H&E. Among the most striking findings were a resident memory T cell-rich sebaceous gland niche and a plasma cell-rich sweat gland niche, suggesting that appendageal structures act as active immunological microenvironments and may contribute to inflammatory memory and disease persistence. Importantly, this atlas is not just descriptive — it is usable. It can support mapping of new datasets, resolve finer cell types and niches, extract microenvironment-driven programs, and enable predictive analyses at scale. More broadly, this work shows what becomes possible when AI, spatial genomics, and atlas-scale data are integrated end-to-end: not just mapping tissues, but systematically decoding them. This was a massive collaboration, and I’m very grateful to the amazing scientists April Foster, Kenny Roberts, and Chloe Admane. Lloyd is an amazing scientist, and I’m especially excited for the community to see more of his work soon — stay tuned. The data and pre-trained models will be released soon. Preprint:

The Chemotherapy Paradox – A "Cure" That Preserves the Root of Cancer? You've been told chemotherapy is a cornerstone of cancer care. But what if the standard of care is fundamentally flawed, suppressing the very system designed to heal you while protecting the engine that drives the disease? In a stunning exposition, Dr. Paul Marik pulls back the curtain on oncology's biggest dilemma. Here's the shocking truth: - Chemotherapy annihilates your immune army. It wipes out your natural killer cells and T-cells—the very soldiers your body needs to fight cancer. You are immune-suppressed, allowing the tumor a clearer path to proliferate. - Chemotherapy preserves the cancer stem cell. This is the root of the tumor. While chemo kills rapidly dividing cells, it often leaves the stem cell—the queen bee—untouched. From this root, the cancer indefinitely divides, mutates, and regrows. - Some chemo drugs may even STIMULATE the stem cell. That's right. The very treatment intended to kill cancer can, in some cases, fuel its source. "So you can't cure the patient unless you get rid of the cancer stem cell," states Dr. Marik. "Interestingly, chemotherapy doesn't kill the stem cell." This explains why "remission" is not a "cure." The cancer can return 7, 8, or 10 years later because the root was never addressed. You are in remission, not cured. The conclusion? The high-dose, "burn-and-cut" approach of traditional oncology is not holistic. It weakens the host and empowers the enemy's most resilient forces. Dr. Marik confirms: The efficacy depends on the tumor type. Cancers with a low percentage of stem cells can see long-term remission. But for many, it's a ticking time bomb. This isn't an opinion; it's a biological reality. It’s time for a paradigm shift. Share this to spark a crucial conversation. The future of oncology depends on it.

Single-cell technologies now let us profile entire transcriptomes in individual cells. But how do we make sense of this complexity in a biologically meaningful way? Many methods summarise cells into a single embedding, but this often comes at the cost of interpretability, especially when multiple gene programs are active at once. We developed Tripso, a self-supervised transformer model that represents cells through multiple gene program-specific embeddings, while also uncovering new programs directly from the data. Instead of collapsing biology into a single vector, Tripso decomposes cell state into multiple representations, each reflecting a different gene program. We explored this across multiple systems. In human hematopoiesis, spanning development to aging, Tripso identified distinct age-associated program activity, including stronger JAK-STAT signalling in early life and dynamic IKZF1-related changes during B cell maturation. By comparing in vitro culture conditions with in vivo hematopoietic stem cell states, Tripso suggested that targeting the SEC61 translocon could enhance stem cell maintenance ex vivo, a prediction that we subsequently validated experimentally. In parallel, we identified a previously uncharacterised tissue-resident memory T-cell program associated with atopic dermatitis and mapped it to distinct spatial immune niches Together, these results show how modelling cells through gene programs can lead to interpretable and experimentally testable insights. More broadly, this work points toward a more interpretable and biologically grounded models of cell state. As single-cell datasets continue to grow, we hope approaches like Tripso will help bridge the gap between data-driven representations and biological insight. This work wouldn’t have been possible without the contributions of an amazing team. Thank you to co-first authors Marie, Tomoya Isobe, Amirhosein Vahidi, Carlo Leonardi, and everyone from roser's Lab, Haniffa Lab, Nicola Wilson and Bertie Gottgens's Lab, bringing together expertise across Cambridge Stem Cell Institute, Open Targets, Wellcome Sanger Institute and Cambridge University. Marie is one of the very best PhD students I have ever supervised. She is truly a force of nature, exceptionally resourceful, deeply innovative, and one of the most impressive scientists I have worked with. I am immensely proud of her and all that she has accomplished. As she begins her internship at Genentech , I have no doubt she will do amazing work there and continue to make her mark. paper: code:
