Suppressive effect of CORM-2 on LPS-induced platelet activation by glycoprotein mediated HS1 phosphorylation interference. [PDF]

PLoS ONE, 2013
In recent years, it has been discovered that septic patients display coagulation abnormalities. Platelets play a major role in the coagulation system.

Mechanisms of receptor/coreceptor-mediated entry of enveloped viruses [PDF]

Biophysical Journal, 96, 2624-2636, (2009), 2008
Enveloped viruses enter host cells either through endocytosis, or by direct fusion of the viral membrane envelope and the membrane of the host cell. However, some viruses, such as HIV-1, HSV-1, and Epstein-Barr can enter a cell through either mechanism, with the choice of pathway often a function of the ambient physical chemical conditions, such as ...

Platelet Apoptosis in Adult Immune Thrombocytopenia: Insights into the Mechanism of Damage Triggered by Auto-antibodies [PDF]

, 2016
Mechanisms leading to decreased platelet count in immune thrombocytopenia (ITP) are heterogeneous. This study describes increased platelet apoptosis involving loss of mitochondrial membrane potential (ΔΨm), caspase 3 activation (aCasp3) and ...

Antibodies against complement-regulatory proteins on platelets in immune thrombocytopenia

Platelets, 2017
In immune thrombocytopenia (ITP), antibodies reacting with platelet membrane glycoproteins (GP) mediate premature platelet cleavage, resulting in thrombocytopenia and therefore a risk of bleeding.

The stochastic entry of enveloped viruses: Fusion vs. endocytosis [PDF]

Biophys. J., 93, 1116-1123, (2007), 2007
Viral infection requires the binding of receptors on the target cell membrane to glycoproteins, or ``spikes,'' on the viral membrane. The initial entry is usually classified as fusogenic or endocytotic. However, binding of viral spikes to cell surface receptors not only initiates the viral adhesion and the wrapping process necessary for internalization,

Combining detection and reconstruction of correlational and quasi-periodic motifs in viral genomic sequences with transitional genome mapping: Application to COVID-19 [PDF]

Journal of Integrated OMICS, 2021, v.11(1) p.5-11, 2020
A method of Transitional Automorphic Mapping of the Genome on Itself (TAMGI) is aimed at combining detection and reconstruction of correlational and quasi-periodic motifs in the viral genomic RNA/DNA sequences. The motifs reconstructed by TAMGI are robust with respect to indels and point mutations and can be tried as putative therapeutic targets.

ALK1 controls hepatic vessel formation, angiodiversity, and angiocrine functions in hereditary hemorrhagic telangiectasia of the liver

Hepatology, EarlyView., 2022
Hepatic endothelial Alk1 signaling protects from development of vascular malformations while maintaining organ‐specific endothelial differentiation and angiocrine portmanteau of the names Wingless and Int‐1 signaling. Abstract Background and Aims In hereditary hemorrhagic telangiectasia (HHT), severe liver vascular malformations are associated with ...

Platelet Apoptosis Can Be Triggered Bypassing the Death Receptors

Clinical and Applied Thrombosis/Hemostasis, 2019
In nucleated cells, the extrinsic pathway of the programmed cell death (apoptosis) is triggered by interaction of death ligands of the tumor necrosis factor superfamily with the death receptors on external cell surface membrane.

Structural basis for the shielding function of the dynamic trypanosome variant surface glycoprotein coat [PDF]

Nature Microbiology 2 (2017), pp. 1523--1532, 2018
The most prominent defence of the unicellular parasite Trypanosoma brucei against the host immune system is a dense coat that comprises a variant surface glycoprotein (VSG). Despite the importance of the VSG family, no complete structure of a VSG has been reported.

Interaction of fibrinogen-magnetic nanoparticle bioconjugates with integrin reconstituted into artificial membranes [PDF]

Nanoscale, 2020, 12, 19918, 2020
Magnetic nanoparticles have a broad spectrum of biomedical applications including cell separation, diagnostics and therapy. One key issue is little explored: how do the engineered nanoparticles interact with blood components after injection? The formation of bioconjugates in the bloodstream and subsequent reactions are potentially toxic due to the ...
