Myelofibrosis causes a pathological remodelling of the bone marrow, which becomes stiffer and more elastic, thus promoting the proliferation of proinflammatory monocytes and their differentiation into dendritic cells.
Early cancer detection typically involves invasive biopsies. Here the authors designed nanosensors that are depolymerized by disease-associated enzymes in vivo to produce fluorescent urinary signals for non-invasive early diagnosis.
Islet transplantation for diabetes treatment requires immunosuppression to control rejection. A microgel presenting Fas ligand with immunomodulatory properties is now shown to prolong the survival of allogeneic islet grafts in vivo.
Molecular simulations reveal the self-assembly of small molecules into nanoparticle drug carriers. Targeting of colon and liver cancer cells by the nanoparticles via kinase inhibitors is employed in anti-tumour therapy in vivo.
Metallic stents have been widely used in coronary angioplasty. Here, the authors develop a resorbable self-expanding stent from polymeric elastomers with high mechanical strength for coronary applications.
