Humans cannot fully heal spinal cord injuries. When the spinal cord is damaged, the body's immune system often spirals into chaos. This overwhelming, inflammatory response creates permanent scar tissue that stops nerve cells from ever repairing themselves or their connections. Zebrafish, however, have mastered the biological art of managing this cellular chaos to completely heal spinal cord damage. In a new study published in the Journal of Neuroinflammation, scientists from the Becker group at the Center for Regenerative Therapies Dresden (CRTD) at TUD Dresden University of Technology and the University of Edinburgh have discovered exactly how zebrafish deploy a specific type of immune cells to gently restore harmony and pave the way for nerve regeneration.

The new findings suggest that acid-suppressing drugs already approved by the FDA could be used to treat or prevent the spread of HR+ breast cancer, the most common form of metastatic breast cancer.

Not every allergy antibody poses the same risk. A Hiroshima University-led research team has developed a more sensitive version of an allergy blood test designed to better detect functional allergen-specific IgE antibodies—the antibodies capable of triggering the immune processes behind allergic reactions.

A major challenge in cuproptosis-based cancer therapy is achieving tumor-selective activation without relying on external copper administration. Published in Biomedical Analysis, a new study from Guizhou Medical University introduces an iRGD-modified PLGA-PEG nanoparticle system that delivers the copper-chelating agent TPEN directly to tumor cells. By exploiting the high copper levels already present in cancer cells, this approach triggers copper-dependent cell death while reducing potential systemic toxicity associated with metal delivery.

Traditional Chinese Medicine (TCM) products contain highly complex mixtures of chemical components, making rapid and reliable quality assessment a major analytical challenge. A new review published in the journal Biomedical Analysis provides a comprehensive assessment of how direct mass spectrometry is being applied to address this challenge. Researchers from institutions including Tianjin University of Commerce have synthesized more than a decade of scientific literature to evaluate the technology’s current capabilities and future potential. The review examines how these rapid analytical techniques, which require little to no sample preparation, can provide immediate chemical insights into herbal products, from raw materials to finished decoctions.

Researchers from Kansas City University School of Medicine have published a scoping review examining the role of astrocytes in chronic traumatic encephalopathy (CTE). Synthesizing evidence from 40 studies, the review suggests that astrocytic dysfunction, neuroinflammation, impaired waste clearance, and disrupted glutamate homeostasis may contribute significantly to disease development and progression. The findings support a shift from a neuron-centric view of CTE toward a broader neuroglial disease model.
