I am following the recent series of pieces "Thinking as a Scientist" with an article on "How to Ask a Biological Question." network.febs.org/posts/think… @FEBSnews This is often easier said than done, as we receive no formal training in this area. I look forward to your views.

💡Exciting news! Our latest study, in collaboration with Prof. Mirela Kuka’s lab, is out now—uncovering how T cell–derived IFN-γ can suppress T follicular helper (TFH) cells and limit antibody responses. 🚀🧵(1/10) embopress.org/doi/full/10.10… 🔬Approach: We used a subcutaneous LCMV infection model, tracking virus-specific CD4⁺ T cells. Surprisingly, we found two T-bet⁺ subsets—one producing granzyme B (GzmB) and another expressing Tcf-1, the latter being a TFHprecursor. (2/10) 🌟Key Finding: IFN-γ from T cells drives the TH1 fate and blocks TFHmaturation. When we blocked IFN-γ early, Tcf-1⁺ “precursor” cells fully developed into TFH, boosting germinal center B cells and antibody responses. (3/10) 📊Mechanism: Rather than acting solely via an “autocrine loop,” IFN-γ shapes the microenvironment by acting on other immune cells—likely dendritic cells—thereby steering CD4⁺ T cells toward a TH1-dominant response at the expense of TFH. (4/10) 📌Infections & Vaccines: We also tested other settings—like systemic infections or even MPLA-based immunizations—and consistently observed that reducing IFN-γ can enhance TFH and humoral immunity. Timing is critical for optimal effect. (5/10) 🧬Broader Impact: Our data help explain why some infections trigger robust TH1activity but limited antibody responses, and highlight how precisely timed IFN-γ modulation could improve immunization strategies. (6/10) 🔑Clinical Relevance: In severe or chronic viral infections, TH1-skewed responses can sometimes block high-affinity antibody production. Targeted IFN-γ blockade might tip the balance toward TFH, aiding pathogen clearance or vaccine success. (7/10) 💡Mechanistic Insights: By tuning IFN-γ signals, we can reprogram local lymph nodes and “unlock” TFH potential. This points toward new avenues to combine T cell and B cell–focused therapies for more effective vaccines. (8/10) 👏Huge congratulations to Mirela Kuka, Eleonora Sala, Maria Nelli and all contributors who co-led the study! (9/10) 📖Dive deeper into our research and its implications for antiviral defense and vaccines. We look forward to your thoughts and questions!

This is a huge decision from the Guardian. I believe too that X has become a polarised political platform that has lost its purpose and sadly, I no longer support it, despite its initial good intention. I will move my activity to @frezzalab.bsky.social theguardian.com/media/2024/n…

🥳 Happy to share our new preprint where we describe the molecular machinery regulating iron transport between lysosomes and mitochondria, how it controls the melanoma drug tolerant persister state and the consequences of its perturbation on ferroptosis 👉 researchsquare.com/article/r…

Today in @CellCellPress we report a new pathway of ketone metabolism. This BHB shunt generates an orphan family of anorexigenic ketone metabolites that are chemical cousins of exercise-inducible Lac-Phe. Congratulations @mariadolores_mg @Stanford_ChEMH cell.com/cell/fulltext/S0092…

Today we are publishing 2 MANUSCRIPTS in @NatureComms 1. @NataliaPardoL discovers the role of nuclear MTHFD2 in centromere stability 2. Espinar and Garcia-Cao reveal the role of nuclear IMPDH2 in the DNA damage response. Nuclear Metabolism is on 🔥
Metabolic enzymes are taking on unexpected "second jobs" within the nucleus, where they orchestrate critical functions like cell division and DNA repair. The discovery by @SdelciL in @NatureComms can help develop new metabolism-based cancer therapies.
