AlphaFold3 Breakthrough: AI Designs Selective IL-2 Activators for Safer CAR T Cell Therapy
CAR T cell therapy shows remarkable cancer-fighting potential, but has a critical flaw: IL-2 activation of CAR T cells also activates regulatory T cells (Tregs), causing severe side effects. Now researchers used AlphaFold3 and physics-constrained machine learning to design an “orthogonal” IL-2/IL-2Rβ system—activating only CAR T cells while sparing other immune cells. The designed variant achieved 0.724 ipTM with just 0.843 Ångström deviation from wild-type structure. AI now moves beyond predicting protein structures to precisely engineering safer immunotherapies.
Methylation Signals in Long-Read Sequencing Make Gene Variant Phasing More Accurate
Gene sequencing isn’t just reading ATCG sequences—it can also read DNA methylation modifications. But existing phasing tools ignore this information. LongHap is the first phasing method integrating sequence and methylation data, optimizing haplotype reconstruction by identifying differentially methylated sites. Tests show LongHap has lower error rates than WhatsHap and HapCUT2, with better phase block continuity, especially for medically relevant gene variants. The “hidden information” in long-read sequencing is finally being unlocked by AI.
Deep Learning + Swin Transformer: Breast Cancer Diagnosis Accuracy Reaches New Heights
Breast cancer imaging diagnosis remains a hot AI healthcare track, but traditional CNNs often miss complex lesions. This paper proposes a new framework combining Swin Transformer with dual-attention multi-scale fusion networks, better capturing subtle imaging features. Swin Transformer’s hierarchical structure lets models see local details while understanding global context, significantly boosting diagnostic accuracy. AI imaging diagnosis is moving from “functional” to “excellent.”
Protein Language Model ESM-2: Accelerating Cyclic Peptide Drug Design via “Peptide Space”
Cyclic peptide design’s challenge: chemical space is vast, random screening is inefficient. Researchers used protein language model ESM-2 to build a “peptide space”—mapping cyclic peptide physicochemical properties to high-dimensional vectors, then uniformly sampling rather than guessing. Experiments show this method produces higher-quality β2-microglobulin-binding peptides than random screening. AI shifts from “brute-force search” to “intelligent navigation.”
DeepMind’s London HQ Platform 37 Opens, Honoring AlphaGo’s Legendary Move 37
DeepMind CEO Demis Hassabis announced Platform 37, the new London headquarters, officially opens—named after AlphaGo’s legendary Move 37 against Lee Sedol. The ground floor will feature “AI Exchange,” a public space hosting exhibitions and events to help people understand AI. While not a technical breakthrough, DeepMind’s influence in AI + life sciences (AlphaFold, AlphaProteo) is undeniable, and the new HQ may incubate more world-changing projects.
