In synucleinopathies, the protein α-synuclein misfolds into Lewy bodies (LBs) in patients with Lewy body disease (LBD) or into glial cytoplasmic inclusions (GCIs) in patients with multiple system atrophy (MSA). The ability of a single misfolded protein to cause disparate diseases is explained by the prion strain hypothesis, which argues that protein conformation is a major determinant of disease. While structural, biochemical, and biological studies show that LBD and MSA patient samples contain distinct α-synuclein strains, we recently reported the unexpected finding of a novel α-synuclein strain in a Parkinson's disease with dementia patient sample containing GCI-like co-pathology along with widespread LB pathology.

Streams and ponds significantly contribute to the global freshwater carbon gases budget. To understand the role of urbanization in affecting aquatic carbon emissions, here we examined the carbon dioxide (CO) and methane (CH) concentrations and diffusive emissions from streams and small ponds across three headwater catchments with varied urbanization intensities in the upper Yangtze River. We found that riverine partial pressure of CO (pCO) and dissolved CH concentration (dCH) increased, while pond pCO and dCH decreased as urban land proportion of catchments increased from 1.

Ferroptosis is a form of cell death caused by iron-dependent phospholipid peroxidation and subsequent membrane rupture. Autophagic degradation of the iron-storage protein ferritin promotes ferroptosis by increasing cytosolic bioactive iron, presumably explaining how lysosomal inhibitors suppress ferroptosis. Surprisingly, we found that lysosomal inhibitors suppress cysteine-deprivation-induced (CDI) ferroptosis, even in autophagy-defective cells, and subsequently discovered that clathrin-mediated endocytosis (CME) of transferrin is essential for CDI ferroptosis.

Proteolysis targeting chimeras (PROTACs) are heterobifunctional degraders with a unique mode of action that permits access to "undruggable" targets. These molecules pose challenges in terms of solubility and bioavailability due to their physicochemical properties. So far, very little information is available on the potential of enabling formulations of PROTACs in pharmacokinetic studies.

Apert syndrome is a recognizable craniofacial condition characterized by craniosynostosis, hypertelorism, exorbitism, midface hypoplasia, and complex symmetrical bony and cutaneous 'mitten' syndactyly of all four limbs. Around 98% of affected patients have one of two heterozygous missense variants in the FGFR2 gene, encoding either p.(Ser252Trp) (S252W) or p.
