Molecular Medicine

Molecular Medicine applies the principles of molecular biology, genetics and biochemistry to understand disease mechanisms, to develop precise diagnostic tools and to design targeted therapies. By interrogating alterations in nucleic acids, proteins, metabolites and signalling networks, this discipline seeks to translate laboratory discoveries into clinical interventions. Key advances include the identification of molecular biomarkers for early detection, the development of gene- and RNA-targeted agents, the use of high-throughput sequencing to guide personalised treatment plans, and the integration of systems biology to model complex pathways. Molecular Medicine thus bridges fundamental research and patient care, offering new prospects for prediction, prevention and individualised management of a wide spectrum of diseases.

Research from Nature Portfolio

Researchers have engineered a fusion protein that anchors the immunosuppressive enzyme indoleamine 2,3-dioxygenase (IDO) to inflamed tissues via a galectin-3 domain. In rodent models of psoriasis, osteoarthritis and periodontal disease, a single injection of this construct persisted for a week at sites of inflammation and restored tissue homeostasis without systemic immune compromise, highlighting a novel strategy for focal immunomodulation. In parallel, cryo-electron microscopy of human Alzheimer’s disease brain tissue has revealed that tau filaments reside within extracellular vesicles enriched in endo-lysosomal proteins. Filament ends are tethered to the vesicle membrane by specific linker densities, suggesting a selective packaging mechanism that may facilitate prion-like spread and interfere with clearance pathways.

Research from all publishers

A hydrogen peroxide–responsive upconversion nanocomposite was developed to inhibit both amyloid-β and tau aggregation while consuming excess reactive oxygen species and providing luminescent tracking of therapeutic release. In rodent Alzheimer’s models, this system suppressed plaque and tangle formation and improved cognitive performance. Separately, a tannic acid–metal nanocomposite carrying manganese ions and a near-infrared fluorophore enabled bimodal magnetic resonance and fluorescence imaging, concurrently neutralised oxidative stress and blocked tau hyperphosphorylation, resulting in restored hippocampal architecture and memory in aged rats. Additionally, biomimetic microglial nanoparticles loaded with flavin mononucleotide crossed the blood–brain barrier to modulate microglial inflammation, enhancing synaptic plasticity and memory in both inflammatory and transgenic Alzheimer’s mouse models.
