Analysis of Rho GTPase signalling pathways regulating epithelial morphogenesis

open access: yes, 2010
Rho GTPases are molecular switches controlling many aspects of cell behaviour, including cell cycle progression, cell division, migration and morphology. The activity of Rho proteins is regulated by conformational changes induced by binding of guanine

Adenylate cyclase influences filamentous haemagglutinin-mediated attachment of Bordetella pertussis to epithelial alveolar cells [PDF]

open access: yes, 2019
Attachment to epithelial cells in the respiratory tract is a key event in Bordetella pertussis colonization. Filamentous haemagglutinin (FHA) is an important virulence factor mediating adhesion to host cells.

A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

open access: yesAdvanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.

Tutorial on the biology of nanotopography [PDF]

open access: yes, 2004
The aims of this short tutorial are fourfold: 1) to introduce readers unfamiliar with the field to major concepts in the field; 2) to inform the reader of major unresolved questions; 3) to inform readers of a few major sources of relevant literature; and

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

open access: yesAdvanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.

Decreased mucosal adhesion of Lactobacillus species in patients with inflammatory bowel disease

open access: yesCaspian Journal of Internal Medicine, 2022
Background: Probiotic Lactobacillus spp. modulate immune response via interactions of their binding proteins with epithelial cells. We studied the presence of attachment protein-encoding genes (mub1, mub2, and mapA) in Lactobacillus strains with ...

Biophysical studies of the gingival epithelium

open access: yesJournal of International Clinical Dental Research Organization, 2011
Objectives: As the gingival epithelial cells undergo transition between the surface, crevicular and junctional areas, it is reported that their resting potential could also get altered due to change/variations in the membrane transport protein ...

Iron stress increases Bordetella pertussis mucin-binding capacity and attachment to respiratory epithelial cells [PDF]

open access: yes, 2007
Whooping cough is a reemerging infectious disease of the respiratory tract caused by Bordetella pertussis. The incomplete understanding of the molecular mechanisms of host colonization hampers the efforts to control this disease.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

open access: yesAdvanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...
