Summary
Environmental toxins damage epithelial barriers, increasing chronic diseases like allergies and autoimmune disorders. This review explores how pollutants compromise skin and mucosal health through cellular and molecular damage.
Area of Science:
- Environmental Science
- Toxicology
- Immunology
Background:
- The epithelial barrier theory posits a link between rising chronic non-communicable diseases and environmental agents disrupting barrier integrity.
- Global pollution and industrialization have increased exposure to toxic agents over six decades, negatively impacting human health.
- Uncontrolled introduction of chemicals has led to adverse effects on skin and mucosal epithelial barriers.
Approach:
- This review synthesizes current research on environmental barrier-damaging compounds.
- It examines the cellular and molecular mechanisms underlying epithelial barrier disruption.
- The interplay between toxic substances, inflammatory diseases, and medications is considered.
Key Points:
- Environmental agents like particulate matter, plastics, and pollutants compromise epithelial barrier integrity.
- Disruption involves tight-junction opening, inflammation, cell death, oxidative stress, and metabolic dysregulation.
- Skin and mucosal barriers are particularly vulnerable to these environmental insults.
Conclusions:
- Environmental exposure to barrier-damaging compounds poses a significant threat to human health.
- Understanding these mechanisms is crucial for developing preventative and therapeutic strategies.
- Further research is needed to address the complex interactions between toxins, disease, and treatment.

01:29Tight Junctions
5.3K
Tight junctions are molecular seals between cells that prevent the leaking of fluids, ions, and other small solutes across cavities and compartments in multicellular organisms. They are mainly composed of claudin and occludin transmembrane proteins, and other proteins such as tricellulin and JAM (junctional adhesion molecule). All these proteins are 4-pass transmembrane proteins, except JAM, which is a single-pass transmembrane protein belonging to the immunoglobulin superfamily. The...

01:25Physiological Barriers
3.6K
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...

1.1K
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...

01:24Cellular Membranes and Drug Transport
560
Drugs must traverse multiple biological barriers, such as multi-layered skin, single-layered intestinal epithelium, and the plasma membrane, to reach their target sites within the body. The plasma membrane, a highly structured composite of phospholipids, carbohydrates, and proteins, is the cell's protective boundary, facilitating selective substance exchange.
Phospholipids arrange themselves into a bilayer, with hydrophilic heads oriented outward and hydrophobic tails facing inward.

01:24Adherens Junctions
4.8K
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

01:19Clinical Applications of Epidermal Stem Cells
2.7K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...
