Polarization vision and the physiological basis for trichromatic vision in Philaenus spumarius: Understanding host‐seeking behaviour in insect vectors for Xylella fastidiosa control

Annals of Applied Biology, EarlyView.
We investigated the role of vision in host‐seeking behaviour by Philaenus spumarius, the main European vector of Xylella fastidiosa, through an integrated anatomical, optical, physiological, and behavioural study. Our data highlight that the spittlebug uses visual cues, including polarized light, which may aid in detecting the polarized reflections ...

ARHGAP18-ezrin functions as an autoregulatory module for RhoA in the assembly of distinct actin-based structures

eLife
The location of different actin-based structures is largely regulated by Rho GTPases through specific effectors. We use the apical aspect of epithelial cells as a model system to investigate how RhoA is locally regulated to contribute to two distinct ...

Distribution of Glycan Motifs at the Surface of Midgut Cells in the Cotton Leafworm (Spodoptera littoralis) Demonstrated by Lectin Binding

Frontiers in Physiology, 2017
Glycans are involved in many biological phenomena, including signal transduction, cell adhesion, immune response or differentiation. Although a few papers have reported on the role of glycans in the development and proper functioning of the insect midgut,

Antigen discrimination by T cells relies on size-constrained microvillar contact

Nature Communications, 2023
T cells can use TCR on microvilli to interact with peptide-MHC (pMHC) complexes on antigen presenting cells. Here the authors characterise how T cells use microvilli to interrogate reconstituted membranes for pMHC complexes and how this is regulated by a

A model for de novo pigmentation of amelanotic retinal pigment epithelial cells

Acta Ophthalmologica, EarlyView.
Abstract Purpose Retinal Pigment Epithelial (RPE) cells perform critical functions in the visual cycle. Their melanin pigmentation, which is organized into specialized compartments – melanosomes, is highly critical for proper vision. A chemical method to induce pigmentation in a non‐pigmented model of ARPE‐19 cells was applied using L‐DOPA as a ...

Serum Villin‐1—A Novel Marker of Gut Barrier Damage in Acutely Decompensated Cirrhosis: A Cohort Study and Validation

Alimentary Pharmacology &Therapeutics, EarlyView.
Serum villin‐1 is a non‐invasive indicator of gut barrier damage and short‐term mortality in acutely decompensated cirrhosis. Incorporating villin‐1 assessment into risk stratification methods improves prognostic accuracy by capturing an essential, yet previously overlooked component of disease progression.

Origin and evolution of microvilli

Biology of the Cell
AbstractBackground InformationMicrovilli are finger‐like, straight, and stable cellular protrusions that are filled with F‐actin and present a stereotypical length. They are present in a broad range of cell types across the animal tree of life and mediate several fundamental functions, including nutrient absorption, photosensation, and mechanosensation.

Erythrocyte ‘Feierzeit’ reaction: Novel filamentous and vesicular response to n‐butyl acetate

Journal of Microscopy, EarlyView.
Abstract Human erythrocytes (red blood cells; RBCs) undergo spontaneous disassembly after several hours of exposure to n‐butyl acetate (nBA). Images of the morphological changes were captured in time‐lapse sequences using differential interference contrast (DIC) light microscopy.

Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs

Journal of Anatomy, EarlyView.
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.

Ultrastructural Analysis of Inflammatory Breast Cancer Cell Clusters in an Ex Vivo Environment Mechanically Mimicking the Lymph Vascular System

Breast Cancer: Basic and Clinical Research, 2021
Background: Inflammatory breast cancer (IBC) is a rare form of breast cancer with a poor prognosis. IBC is characterized by florid lymphovascular tumor emboli in the skin and the parenchyma of the breast.
