  • Immune system regulation for nanoparticle drug delivery. Breaking the endless cycle in nanomedicine science news VI.14

    The journey of discovery in scientific research sometimes follows a familiar path: discover, admire, investigate, disappoint, and forget. Nevertheless, in some disciplines, it seems repeating many times. One of such cycles in the field of immune system blockade by nanoparticles is analysed in a recent article published in Nature Communications journal. Scientists from the Institute of Bioorganic Chemistry, Uppsala University and Boston University propose that advancements in nanomaterial development may finally disrupt this cycle, potentially introducing the method of macrophage blockade into clinical practice to improve cancer therapy.

  • Loss of Ability to regenerate Limbs in Higher Vertebrates: From Side Effects of Evolutionary Innovations to Gene Loss science news VI.5

    Researchers from the Laboratory of Molecular Foundations of Embryogenesis at the GNC IBCh RAS have identified the main factors that rendered limb regeneration impossible in modern amniotes (reptiles, birds, and mammals). The authors suggested that after the ancestors of amniotes transitioned to land, their ability to regenerate limbs was suppressed by the side effects of various innovations that emerged at that time, which were necessary for successful colonization of land. This, in turn, stimulated the disappearance of many genes that ceased to participate in regeneration from that moment on. As a result, in modern amniotes, including humans, the inability to regenerate limbs became firmly fixed at the genomic level.

  • Innovative Contact Lenses with Metal-Organic Frameworks for Glaucoma Treatment science news V.13

    Researchers from the Institute of Bioorganic Chemistry of the Russian Academy of Sciences, Harvard University, Sechenov University, the Pasteur Institute, and other scientific institutions in Russia and abroad have proposed a new method for controlling elevated intraocular pressure, which is a major damaging factor in glaucoma. They have developed a new type of contact lenses that incorporate metal-organic frameworks (MOFs) for the controlled and prolonged release of brimonidine, a medication used to reduce intraocular pressure. This innovation was presented in the high-ranking scientific journal Aggregate, highlighting its innovative nature and potential impact on ophthalmological practice.
