Ca2+ Influx and Tyrosine Kinases Trigger Bordetella Adenylate Cyclase Toxin (ACT) Endocytosis. Cell Physiology and Expression of the CD11b/CD18 Integrin Major Determinants of the Entry Route
(Public Library Publishing, 2013-09)
Humans infected with Bordetella pertussis, the whooping cough bacterium, show evidences of impaired host defenses. This pathogenic bacterium produces a unique adenylate cyclase toxin (ACT) which enters human phagocytes and ...
Human LDL Structural Diversity Studied by IR Spectroscopy
(Public Library Science, 2014-03-18)
Lipoproteins are responsible for cholesterol traffic in humans. Low density lipoprotein (LDL) delivers cholesterol from liver to peripheral tissues. A misleading delivery can lead to the formation of atherosclerotic plaques. ...
Role of Monoubiquitylation on the Control of IκBα Degradation and NF-κB Activity
(Public Library of Science, 2011-10-12)
The NF-κB pathway is regulated by multiple post-translational modifications including phosphorylation, ubiquitylation and SUMOylation. Many of these modifications act on the natural inhibitor IκBα modulating its capacity ...
Familial Hypercholesterolemia: The Most Frequent Cholesterol Metabolism Disorder Caused Disease
(MDPI, 2018-11-01)
Cholesterol is an essential component of cell barrier formation and signaling transduction involved in many essential physiologic processes. For this reason, cholesterol metabolism must be tightly controlled. Cell cholesterol ...
Validation of LDLr Activity as a Tool to Improve Genetic Diagnosis of Familial Hypercholesterolemia: A Retrospective on Functional Characterization of LDLr Variants
(MDPI, 2018-06)
Familial hypercholesterolemia (FH) is an autosomal dominant disorder characterized by high blood-cholesterol levels mostly caused by mutations in the low-density lipoprotein receptor (LDLr). With a prevalence as high as ...
Characterization of the Intrinsic Phospholipase A1 Activity of Bordetella pertussis Adenylate Cyclase Toxin
(MDPI, 2018-12-04)
Adenylate cyclase toxin (ACT, CyaA) is one of the important virulence factors secreted by the whooping cough bacterium Bordetella pertussis, and it is essential for the colonization of the human respiratory tract by this ...
Ubiquitylation Dynamics of the Clock Cell Proteome and TIMELESS During a Circadian Cycle
(Cell Press, 2018-05-22)
Circadian clocks have evolved as time-measuring molecular devices to help organisms adapt their physiology to daily changes in light and temperature. Transcriptional oscillations account for a large fraction of rhythmic ...
Physico-chemical interactions between compartment-forming lipids and other prebiotically relevant biomolecules
(EDP Sciences, 2014)
Lipids are essential constituents of contemporary living cells, serving as structural molecules that are necessary to form membranous compartments. Amphiphilic lipid-like molecules may also have contributed to prebiotic ...
Data on interleukin (IL)-2- and IL-15-dependent changes in IL-2Rβ and IL-2Rγ complexes
(Elsevier, 2017-04)
We provide detailed datasets from our analysis of the proteins that associate with IL-2Rbeta and IL-2Rgamma in T-cells stimulated with IL-2 or IL-15 compared with resting T-cells, as identified by SILAC-based quantitative ...
Understanding the Mechanism of Translocation of Adenylate Cyclase Toxin across Biological Membranes
(MDPI, 2017-09-21)
Adenylate cyclase toxin (ACT) is one of the principal virulence factors secreted by the whooping cough causative bacterium Bordetella pertussis, and it has a critical role in colonization of the respiratory tract and ...
