Sometimes, scientific progress comes from conceptual insights that arrive in a flash. More often, however, such progress arrives in a decidedly less glamorous, though no less important, manner.

Researchers report in the June 21, 2021, online issue of Neuron that overexpression of the LDL receptor can reduce ApoE to prevent tauopathy-associated neurodegeneration in mouse models.

Multiple companies are pursuing CD47-blockade as a tumor immunotherapy approach. Sana Biotechnology Inc., too, is interested in the therapeutic potential of CD47 – but from a very different angle. By overexpressing CD47 on stem cells, researchers at Sana want to make transplanted cells invisible to the immune system.

A deficiency in neurotrophic factor signaling has been shown to exacerbate environmental risk factors for the development of Alzheimer's disease pathogenesis in mice, according to a study reported in the June 22, 2021, online edition of the Proceedings of the National Academy of Sciences.

PERTH, Australia – Researchers at RMIT University and St. Vincent's Hospital in Melbourne have flipped traditional 3D printing to create more intricate biomedical structures, advancing new technologies for regrowing bones and tissue. Instead of making the bioscaffolds directly, the team 3D printed molds with intricately patterned cavities and then filled them with biocompatible materials, before dissolving the molds away.

Sometimes, scientific progress comes from conceptual insights that arrive in a flash. More often, however, such progress arrives in a decidedly less glamorous, though no less important, manner – through the development of new technologies in what can be a very slow iterative cycle of getting a new method to work.

Researchers from The Hong Kong Polytechnic University said they have used two-dimensional nanosheets to develop a biomimetic nanosheet that can monitor tumor development, treat tumors and monitor the treatment progress in real-time.

A China-U.S. study led by scientists at China Pharmaceutical University (CPU) and Harvard University has identified a new small-molecule antagonist of the stimulator of interferon genes (STING) signaling pathway, SN-011, and shown it to be safe, effective and specific in STING-driven inflammatory diseases.

Researchers from The Hong Kong Polytechnic University (PolyU) said they have used two-dimensional nanosheets (FePSe3) to develop a biomimetic nanosheet that can monitor tumor development, treat tumors and monitor the treatment progress in real-time. With positive results from mice, the team hopes to further test it on larger animals, then move on to clinical studies.
