Once confined to a niche in nuclear medicine, targeted radionuclide therapy is rapidly gaining momentum and becoming one of the fastest-growing strategies in oncology. Evidence of this surge was clear at the 2026 European Society of Medical Oncology Targeted Anticancer Therapy (ESMO TAT) congress, where the topic was highlighted both at the ESMO Colloquium and in the session titled “The Future of Radioligands: Insights from Industry, Regulation and Clinical Practice,” with various speakers sharing their perspectives on the modality’s current role and future potential.

In the opening sessions of this year’s ESMO Targeted Anticancer Therapies Congress, Elena Garralda, director of the Molecular Therapeutics Research Unit at Vall d’Hebron Institute of Oncology in Barcelona, described ESMO TAT as “the house of phase I,” a fitting label for a meeting centered on translational research and early drug development, where first-in-human data and new trial designs help shape the next generation of cancer therapies.

Researchers at INSERM and collaborators have identified hypothalamic tanycytes as mediators of tau clearance and shown that their structural and genetic disruption may drive Alzheimer’s disease pathology.

Researchers at INSERM and collaborators have identified hypothalamic tanycytes as mediators of tau clearance and shown that their structural and genetic disruption may drive Alzheimer’s disease (AD) pathology. AD is characterized by the buildup of extracellular amyloid-β plaques and intracellular tau tangles, protein aggregates that disrupt neuronal function and drive neurodegeneration.

Building on the foundation laid in 2020, researchers at the University of California, San Francisco (UCSF) have now shown that targeting the GPI-anchored vascular enzyme TNAP can reproduce the cognitive benefits previously attributed to the liver-derived exercise factor GLPD1.

Hepatocellular carcinoma (HCC) is the most common form of primary liver cancer, representing approximately 75-85% of all cases. Often considered preventable, primary liver cancer ranks as the sixth most frequently diagnosed cancer and the third leading cause of cancer deaths worldwide. Through a multi-institutional effort, researchers have identified activated ATF6α as a driver of HCC that suppresses immune defenses, predicts response to immune checkpoint therapy, and represents a potential target for intervention.

Chemotherapy is often seen solely as a tumor-targeting treatment, yet new evidence reveals a paradox: the tissue injury it causes can reprogram the body’s defenses, influencing the risk of metastasis. Researchers from the University of Lausanne and collaborators reported that chemotherapy reshapes the gut-immune axis by inducing microbiota-derived indole-3-propionic acid, which reprograms myelopoiesis to curb monocyte-driven immunosuppression and metastasis in colorectal cancer.

Researchers from the University of Lausanne and collaborators reported that chemotherapy reshapes the gut-immune axis by inducing microbiota-derived indole-3-propionic acid (IPA), which reprograms myelopoiesis to curb monocyte-driven immunosuppression and metastasis in colorectal cancer (CRC).

For decades, scientists have searched for a mechanistic link between viral infection and multiple sclerosis (MS). Insights from three studies recently published in Cell bring that connection into sharper focus. By tracing how the immune system responds to Epstein-Barr virus (EBV) – and how those responses can misfire against the brain – researchers are beginning to uncover a compelling biological explanation for MS.

Over the course of the year, and continuing into the latest scientific meetings, an extraordinary breadth of new antibody-drug conjugate (ADC) designs was reported, with innovations spanning targets, linkers, payloads, conjugation chemistries and overall architectures. Once defined by a simple “one target, one payload” model, the field is lately expanding into a more versatile and diverse therapeutic space.
