Interaction of bacterial extracellular microvesicles with eukaryotic cells.

open access: yesМедицинская иммунология, 2021
Bacterial extracellular microvesicles (BMV) are formed by nonpathogenic, pathogenic and opportunistic bacteria. BMV are spherical bilayer-membrane organelles containing different cargoes: lipopolysaccharides, pathogen associated molecular patterns (PUMP),

Molecular dissection of the domain architecture and catalytic activities of human PrimPol [PDF]

open access: yes, 2014
PrimPol is a primase–polymerase involved in nuclear and mitochondrial DNA replication in eukaryotic cells. Although PrimPol is predicted to possess an archaeo-eukaryotic primase and a UL52-like zinc finger domain, the role of these domains has not been ...

Biomembranal Myristoyl-Phosphatidylcholine as a Potential Target of the Cell Injury Activity of Vitamin D Decomposition Products in Eukaryotic Cells

open access: yesFrontiers in Bioscience-Landmark
Background: Vitamin D decomposition products target a myristic acid sidechain of the predominant glycerophospholipid constructed in the biomembranes of Helicobacter pylori, causing gastric cancer in humans, and disrupt the membrane ...

Redox compartmentalization in eukaryotic cells [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - General Subjects, 2008
Diverse functions of eukaryotic cells are optimized by organization of compatible chemistries into distinct compartments defined by the structures of lipid-containing membranes, multiprotein complexes and oligomeric structures of saccharides and nucleic acids.

Diverged composition and regulation of the Trypanosoma brucei origin recognition complex that mediates DNA replication initiation [PDF]

open access: yes, 2016
Initiation of DNA replication depends upon recognition of genomic sites, termed origins, by AAA+ ATPases. In prokaryotes a single factor binds each origin, whereas in eukaryotes this role is played by a six-protein origin recognition complex (ORC).

The symbiotic origin of the eukaryotic cell

open access: yesComptes Rendus. Biologies, 2023
Eukaryogenesis represented a major evolutionary transition that led to the emergence of complex cells from simpler ancestors. For several decades, the most accepted scenario involved the evolution of an independent lineage of proto-eukaryotes endowed with an endomembrane system, including a nuclear compartment, a developed cytoskeleton and phagocytosis,

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.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
