Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

IL-18 and IL-18 binding protein concentration in ovarian follicular fluid of women with “tubal factor” subjected to in vitro fertilization

Postępy Higieny i Medycyny Doświadczalnej, 2013
Composition of follicular fluid is also regarded to be linked to quality of oocytes, fertilization and quality of the embryo. The aim of this study was to investigate the concentration of IL-18 and IL18BP in follicular fluid (FF) in a homogeneous group of women with sterility caused by "tubal factor" subjected to in vitro fertilization (IVF) and the ...

Supplementary Figure S4 from The IL-18 Antagonist IL-18–Binding Protein Is Produced in the Human Ovarian Cancer Microenvironment

, 2023
<p>Supplementary Figure S4 - PDF file 640K, Immunochemical analysis of IL-18BP expression in EOC cell lines and xenotransplants. Immunochemistry with an anti-IL-18BP Ab shows virtually no reactivity in EOC cell lines (A upper left panel, B left panel), whereas IL-27-cultured A2774 cells (B middle panel) and areas of orthotopic SKOV3 (A) and A2774

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Cumulative mutagenesis of the basic residues in the 201-218 region of insulin-like growth factor (IGF)-binding protein-5 results in progressive loss of both IGF-I binding and inhibition of IGF-I biological action [PDF]

, 2005
We have reported previously that mutation of two conserved nonbasic amino acids (G203 and Q209) within the highly basic 201–218 region in the C-terminal domain of IGF-binding protein-5 (IGFBP-5) decreases binding to IGFs.
