Intercellular adhesion molecules can be classified as Ca2+ dependent or Ca2+ independent. This classification has significant functional implications regarding cellular interactions. The best characterized Ca2(+)-dependent adhesion molecules, such as L-CAM or E-cadherin, belong to the family of closely related cell surface molecules called cadherins. On the other hand, those immunoglobulin supe...

  Occurrence of adhesions after pelvic and abdominal surgery is a well known problem. Previous surgical procedures are by far the most common cause of intra abdominal a adhesion. In over  10℅ of infertile women, adhesion formation is the main cause of their problem. Moreover postoperative adhesions are the most common cause of intestinal obstruction in the Western world. Although the cause of ...

We propose a novel design of a biomimetic micro-structured surface, which exhibits controlled strongly direction-dependent adhesion properties. The micro-system consists of parallel elastic wall-like structures covered by a thin layer. Numerical calculations have been carried out to study the adhesive properties of the proposed system and to provide design criteria with the aim of obtaining opt...

The CD11b/CD18 integrin plays a crucial role in cell-cell adhesion processes. Recently, we described a case of severe neonatal alloimmune neutropenia (NAIN) caused by an alloantibody against a variant of the CD11b subunit (Mart alloantigen). Allele-specific transfected cells allowed us to demonstrate that an H61R point mutation is directly responsible for the formation of Mart epitopes. No diff...

Ozone modification method and air-oxidation were used for the surface treatment of polyacrylonitrile(PAN)-based carbon fiber. The surface characteristics of carbon fibers were characterized by X-ray photoelectron spectroscopy (XPS). The interfacial properties of carbon fiber reinforced polyamide 6 (CF/PA6) composites were investigated by means of the single fiber pull-out tests. As a result...

This study examined changes in the biomechanical properties of cultured pulmonary microvascular endothelial cells (ECs) and neutrophils induced by adhesion of neutrophils to these ECs. The biomechanical properties of cells were evaluated using magnetic twisting cytometry, which measures the angular rotation of ferromagnetic beads bound to cells through antibody ligation on application of a spec...

Developed nanostructured innovative carbon materials (nano graphite) have a unique combination of properties. These include: high electronic conductivity, magnetic properties, level adhesion and cohesion low density. Using these properties nano graphite allow fabricating the electrode for batteries without binder, effectively modifying electrodes, which affect mechanism redox electrochemical pr...

Anti-Biofouling Coatings In article number 2201152, Robert Texidó, Pol Cabanach, Abdon Pena-Francesch, and colleagues use a coating strategy combining dopamine zwitterionic polymers to prevent bacteria from adhering soft flexible materials commonly used in medical devices. The coatings exhibit superhydrophilic anti-biofouling properties, leading >99% reduction bacterial adhesion. This bacteriop...

Leukocyte recruitment from the bloodstream to surrounding tissues is an essential component of the immune response. Capture of blood-borne leukocytes onto vascular endothelium proceeds via a two-step mechanism, with each step mediated by a distinct receptor-ligand pair. Cells first transiently adhere, or "roll" (via interactions between selectins and sialyl-Lewis-x), and then firmly adhere to t...

Photopolymerized hydrogels are extensively investigated for various tissue engineering applications, primarily due to their ability to form hydrogels in a minimally invasive manner. Although photocrosslinkable hydrogels provide necessary biological and chemical characteristics to mimic cellular microenvironments, they often lack sufficient mechanical properties. Recently, nanocomposite approach...
