Astrocyte molecular signatures in Huntington’s disease

Huntington’s disease is a neurodegenerative disorder caused by a dominant mutation in the HTT gene, resulting in production of mutant huntingtin protein (mHTT). Deletion of mHTT specifically from astrocytes slowed disease progression. Now, Diaz-Castro et al. determined astrocyte … | Continue reading

Biodegradable tube releases growth factor&guides nerve regrowth to bridge gaps

Injuries to peripheral nerves that result in small gaps can heal after reapproximation; however, large gaps that occur after severe injuries require autograft implantation. As an alternative to autografts, Fadia et al . developed biodegradable polymer scaffolds that release a neu … | Continue reading

Tau-PET, not β-amyloid-PET in early Alzheimer's may predict future brain atrophy

Understanding the dynamic of the two major hallmark of Alzheimer’s disease (AD), tau protein and β-amyloid, in the brain could allow better disease management. The use of positron emission tomography (PET) with specific radiotracers allows the visualization of tau-containing neur … | Continue reading

Embryonic CaVβ1 isoform promotes muscle mass maintenance via GDF5 in adult mice

The mechanisms mediating age-related muscle atrophy are not completely understood. Now, Traoré et al . used mouse models to elucidate the mechanisms mediating age-related muscle atrophy. The authors first showed that muscle denervation triggered compensatory mechanisms to counter … | Continue reading

In vivo liquid biopsy: Laser-induced photoacoustic detection of melanoma cells

Circulating tumor cells in patients’ blood can offer insight into the underlying tumor and can also seed distant metastases. Thus, accurate detection of these cells could help with prediction of metastasis, as well as facilitate their elimination. Unfortunately, conventional meth … | Continue reading

The vermiform appendix impacts the risk of developing Parkinson’s disease

Misfolded α-synuclein is a pathological hallmark of Parkinson’s disease (PD). Killinger et al . now report that the human appendix contains an abundance of misfolded α-synuclein and that removal of the appendix decreased the risk of developing PD. The appendix of both PD cases an … | Continue reading

Nondestructive tissue analysis: cancer diagnosis by handheld mass spectrometry

Although a surgeon’s goal is to remove cancer in its entirety during excision surgery, achieving negative margins (absence of cancer cells at the outer edge of the excised tumor specimen) can be challenging. To facilitate intraoperative diagnosis, Zhang et al. developed a handhel … | Continue reading
