Assessing Rab5 Activation in Health and Disease.

Methods in molecular biology (Clifton, N.J.)

PMID: 34453725
Methods Mol Biol. 2021;2293:273-294. doi: 10.1007/978-1-0716-1346-7_20.

The endocytic pathway is a system of dynamically communicating vesicles, known as early endosomes, that internalize, sort, and traffic nutrients, trophic factors, and signaling molecules to sites throughout the cell. In all eukaryotic cells, early endosome functions are regulated...

OBJECTIVE: To assess the incidence of colonization and infection with carbapenemase-producing Enterobacteriaceae (CPE) and carbapenem-resistant Acinetobacter baumannii (CR-Ab) in the ICUs of our city hospitals before and during the coronavirus disease 2019 (COVID-19) pandemic.METHODS: We conducted a multicenter, before-and-after,...

Endosomal Dysfunction Induced by Directly Overactivating Rab5 Recapitulates Prodromal and Neurodegenerative Features of Alzheimer's Disease.

Cell reports

Cell Rep. 2020 Nov 24;33(8):108420. doi: 10.1016/j.celrep.2020.108420.

Neuronal endosomal dysfunction, the earliest known pathobiology specific to Alzheimer's disease (AD), is mediated by the aberrant activation of Rab5 triggered by APP-β secretase cleaved C-terminal fragment (APP-βCTF). To distinguish pathophysiological consequences specific to overactivated Rab5 itself, we activate...

Conformation dependent monoclonal antibodies distinguish different replicating strains or conformers of prefibrillar Aβ oligomers.

Molecular neurodegeneration

Kayed R, Canto I, Breydo L, Rasool S, Lukacsovich T, Wu J, Albay R, Pensalfini A, Yeung S, Head E, Marsh JL, Glabe C.

Mol Neurodegener. 2010 Dec 13;5:57. doi: 10.1186/1750-1326-5-57.

BACKGROUND: Age-related neurodegenerative diseases share a number of important pathological features, such as accumulation of misfolded proteins as amyloid oligomers and fibrils. Recent evidence suggests that soluble amyloid oligomers and not the insoluble amyloid fibrils may represent the primary...
