Anemonefish use sialic acid metabolism as Trojan horse to avoid giant sea anemone stinging

BMC Biology
Background Anemonefish association with sea anemones is a prime example of mutualistic symbiosis. These fish live inside the sea anemone, benefitting from the protection of its toxic nematocysts, and in return, protect the anemone from its own predators.

Automated Label‐Free Assay for Viral Detection and Inhibitor Screening via Biomembrane‐Functionalized Microelectrode Arrays

Advanced Materials, EarlyView.
A bioelectronic sensor integrating 2D cell membranes with organic microelectrode arrays enables detection of SARS‐CoV‐2 fusion pathways. Natively‐expressed viral receptors promote monitoring of viral entry and screening of antibody‐based inhibitors.

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

Advanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Sialic acids, sialoconjugates and enzymes of their metabolism in fungi

Biotechnology & Biotechnological Equipment, 2021
Sialic acids (Sia) represent a set of derivatives of nine-carbon sugar neuraminic acid that occupy a terminal position in oligosaccharide chains located on the surface of cells. They are very important for several physiological and pathological processes,

Siglec-E promotes β2-integrin-dependent NADPH oxidase activation to suppress neutrophil recruitment to the lung [PDF]

, 2014
Siglec-E is a sialic acid-binding Ig-like lectin expressed on murine myeloid cells. It has recently been shown to function as a negative regulator of β2-integrin-dependent neutrophil recruitment to the lung following exposure to lipopolysaccharide (LPS).

An Anti‐Myd88 Peptide Synergistically Enhances the Anti‐Inflammatory Effects of Extracellular Vesicles from Naïve Umbilical Cord MSC or HEK293F CD24 Overexpressing Cells

Advanced Materials Interfaces, EarlyView.
This study confirms that extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) or HEK293F cells overexpressing CD24 have anti‐inflammatory effects in macrophages and monocytes. Further loading either of these EVs with an anti‐Myd88 peptide synergistically enhanced the anti‐inflammatory effects of the EVs.
