Mucus covers all wet epithelia and acts as a protective barrier. In the airways of the lungs,
the viscoelastic mucus meshwork entraps and clears inhaled materials and efficiently …

The airway epithelium together with the mucus layer coating it forms a protective system that
efficiently filters and removes potentially harmful particles contained in inhaled air. The same …

Airway mucus is a complex viscoelastic gel that provides a defensive physical barrier and
shields the airway epithelium by trapping inhaled foreign pathogens and facilitating their …

Although the mucus layer is the first biological barrier encountered by inhaled drugs upon
their deposition in the upper airways, its potential impact on drug dissolution and absorption …

The mucus lining of the respiratory tract originates from products of secretory cells
interspersed among mucosal cells or within submucosal glands and protects the underlying …

As asthma worsens, occlusion of airways with mucus significantly contributes to airflow
obstruction and reduced lung function. Recent evidence from clinical studies has shown …

The respiratory mucus is a very complex biological material, which possesses both flow and
deformation rheological properties, characterized by non-linear and time-dependent …

The respiratory tract harbors a stable and diverse microbial population within an
extracellular mucus layer. Mucus provides a formidable defense against infection and …

In the lung, the airway epithelium produces secreted and tethered mucin biopolymers to
form a mucus hydrogel layer and a surface-attached polymer brush layer. These layers work …

Background Infectious respiratory diseases are transmitted to non-infected subjects when an
infected person expels pathogenic microorganisms to the surrounding environment when …
