Small oligomers formed during the aggregation of certain peptides and proteins are highly cytotoxic in numerous neurodegenerative disorders. Because of their transient nature and conformational heterogeneity, however, the structural and biological features of these oligomers are still poorly understood. Here, we describe a method of generating stable oligomers formed by the Alzheimer's Aβ40 ...Ryan Limbocker The molecular composition of the plasma membrane plays a key role in mediating the susceptibility of cells to perturbations induced by toxic molecules.The aggregation of α-synuclein (Fig. 1A), an intrinsically disordered protein expressed at high levels in the brain, is closely associated with the pathogenesis of a variety of neurodegenerative disorders, collectively known as α-synucleinopathies, including Parkinson’s disease (PD), dementia with Lewy bodies (DLB), and multiple-system …Based on a further analysis of 27 individuals at sites associated with big-game hunting tools, Haas et al. concluded that between 30% and 50% of Late Pleistocene and Early Holocene big game hunters in the Americas may have been women, suggesting that this endeavor may have once been more gender neutral than previously assumed.Ryan Limbocker Christopher M.

Protein AMPylation is a conserved posttranslational modification with emerging roles in endoplasmic reticulum homeostasis. However, the range of substrates and cell biological consequences of AMPylation remain poorly defined.Limbocker R, 0000-0002-6030-6656, United States Military Academy Knowles TPJ, 0000-0002-7879-0140 , University of Cambridge Natural Product Reports , 20 Apr 2022 , 39(4): 742-753A naturally occurring steroid made by the dogfish shark prevents the buildup of a lethal protein in animal studies, reports an international team of researchers.

Here, we identify a small molecule capable of binding and sequestering the amyloid-β peptide (Aβ) in its monomeric, soluble state. Our analysis reveals that this compound interacts with Aβ and inhibits both the primary and ...…
