Physiological Barriers

5.3K
Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...

Mucosal Barrier of the Stomach

2.5K
The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Area of Science:

  • Biomedical Engineering
  • Mucosal Immunology
  • Drug Delivery Systems

Background:

  • Mucus forms a dynamic barrier regulating transport of molecules, particles, and microbes to epithelial surfaces.
  • Understanding mucus barrier function is crucial for targeted drug delivery and preventing pathogen interaction.

Purpose of the Study:

  • To review mechanisms of mucus barrier selectivity.
  • To outline methods for engineering mucus barrier properties (strengthening or weakening).
  • To discuss strategies for designing drug carriers for mucus penetration.

Main Methods:

  • Literature review of mucus structure, composition, and barrier function.
  • Analysis of stimuli-induced changes in mucus properties.
  • Examination of drug carrier and formulation design principles for mucus traversal.

Main Results:

  • Mucus barrier properties can be modulated by altering its structure and composition.
  • Specific stimuli can be used to engineer mucus for desired barrier effects.
  • Drug carrier design and formulation are key to overcoming mucus barriers.

Conclusions:

  • Mucus engineering offers therapeutic potential by modulating barrier function.
  • Targeted drug delivery across mucus requires tailored carrier and formulation strategies.
  • Further research into mucus-epithelial interactions can advance mucosal therapeutics.
