The entry of diphtheria toxin into the mammalian cell cytoplasm: evidence for lysosomal involvement [PDF]

open access: yes, 1980
Lysosomotropic amines, such as ammonium chloride, are known to protect cells from the cytotoxic effects of diphtheria toxin. These drugs are believed to inhibit the transport of the toxin from a receptor at the cell exterior into the cytoplasm where a ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Construction of Triphenylamine-Based Aggregation-Induced Emission Luminogens for Lysosomes Imaging and Its Application in the Photodynamic Therapy of Cancer Cells

open access: yesMolecules
Lysosomes are important acidic subcellular organelles whose dysfunction can lead to some related diseases. The development of new lysosome-imaging-guided AIEgens for the photodynamic therapy of cancer cells is important.

Organelle Cooperation in Stem Cell Fate: Lysosomes as Emerging Regulators of Cell Identity

open access: yesFrontiers in Cell and Developmental Biology, 2020
Regulation of stem cell fate is best understood at the level of gene and protein regulatory networks, though it is now clear that multiple cellular organelles also have critical impacts.

Increase of Claudin-5, ICAM-1 and eNOS expressions in human brain endothelial cells by ammonium chloride

open access: yesTürk Biyokimya Dergisi, 2023
Lysosomal dysfunction could lead to a failure in the degradation process of waste materials, especially for the elimination of aggregated, misfolded and senescence proteins or organelles.

ALIX binds a YPX(3)L motif of the GPCR PAR1 and mediates ubiquitin-independent ESCRT-III/MVB sorting. [PDF]

open access: yes, 2012
The sorting of signaling receptors to lysosomes is an essential regulatory process in mammalian cells. During degradation, receptors are modified with ubiquitin and sorted by endosomal sorting complex required for transport (ESCRT)-0, -I, -II, and -III ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

PLEKHM1 Overexpression Impairs Autophagy and Exacerbates Neurodegeneration in rAAV-α-Synuclein Mice

open access: yesCells
The aggregation of α-synuclein (αSyn) is a central feature of Parkinson’s disease (PD) and other synucleinopathies. The efficient clearance of αSyn depends largely on the autophagy–lysosomal pathway.

In vivo delivery of transcription factors with multifunctional oligonucleotides. [PDF]

open access: yes, 2015
Therapeutics based on transcription factors have the potential to revolutionize medicine but have had limited clinical success as a consequence of delivery problems. The delivery of transcription factors is challenging because it requires the development
