Tight Junctions

Tight Junctions

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...

Epithelial Tissues and Their Functions

Epithelial Tissues and Their Functions

Epithelial tissues are large sheets of cells covering all of the surfaces of the body. These surfaces can be internal or external, for example, skin, airways, the digestive tract, the urinary system, and the reproductive system. Hollow organs and body cavities that do not connect to the body's exterior, including blood vessels and serous membranes, are lined by epithelial tissue known as the endothelium.
Epithelial tissues provide the body's first line of protection from physical, chemical, and...

Accessory Structures of the Eye

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Surface Membrane Barriers

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...

Microbiome of the Eye

Microbiome of the Eye

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

Area of Science:

Corneal epithelium structure and function in ocular drug delivery.

Context:

The corneal epithelium's stratified structure includes superficial, intermediate, and basal cells, crucial for ocular surface protection.
Epithelial integrity is vital for preventing microbial colonization and infection.
The corneal epithelium is the primary barrier for topical drug penetration into the eye.

Purpose:

To elucidate the structural and functional characteristics of the corneal epithelium relevant to drug penetration.
To identify the pathways and influencing factors of topical drug penetration through the corneal epithelium.

Summary:

The corneal epithelium, a stratified squamous epithelium, comprises three cell layers: superficial, intermediate, and basal, connected by junctional complexes.
Its integrity serves a protective role against microbial invasion and infection.
Topical drug penetration occurs via intracellular (intracell) and paracellular (pericell) pathways, influenced by ocular and drug-specific factors.

Impact:

Understanding corneal epithelium dynamics is key for optimizing topical ophthalmic drug delivery and efficacy.
This knowledge aids in designing drugs with improved penetration characteristics.
Highlights the importance of epithelial integrity in maintaining ocular health and treatment success.
