Cytoskeletal Linker Proteins - Plakins01:09

Cytoskeletal Linker Proteins - Plakins

3.0K
Plakins are large proteins with binding domains for microtubules, microfilaments, intermediate filaments, and membrane-associated protein complexes at cell junctions. Plakin functions are evolutionarily conserved and are primarily involved in organizing the different components of the cytoskeleton by crosslinking them to each other and connecting them to the cell-matrix and cell adhesion complexes. They are also known to interact with signal transducers, serve as scaffolds for signaling...

Mechanism of Filopodia Formation01:39

Mechanism of Filopodia Formation

3.4K
Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...

Types of Intermediate Filaments01:31

Types of Intermediate Filaments

5.1K
The intermediate filaments are an essential component of the cytoskeleton. Presently six types of intermediate filament have been identified. Type I and II are acidic and basic keratin proteins. Type III is of mesodermal origin and comprises four proteins: vimentin, desmin, glial fibrillary acidic protein (GFAP), and peripherin. Vimentin is commonly found in mesenchymal cells, desmin in muscle cells, GFAP in astrocytes, while peripherin is found in peripheral nervous system neurons (PNS). Type...

Skin Diseases and Disorders

6.1K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Desmosomes01:05

Desmosomes

8.9K
The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are  essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein...

Microbiome of the Eye01:22

Microbiome of the Eye

3
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:

  • Dermatology and Molecular Biology
  • Skin barrier function research

Background:

  • Filaggrin is essential for epidermal structure and skin homeostasis.
  • Filaggrin deficiency, inherited or acquired, is a key factor in atopic dermatitis (AD) pathogenesis.
  • AD is a common chronic eczematous skin condition affecting all age groups.

Purpose of the Study:

  • To elaborate on the consequences of filaggrin deficiency.
  • To characterize filaggrin structure and function using experimental models.
  • To explore novel therapeutic strategies for AD based on filaggrin restoration.

Main Methods:

  • Review of current knowledge on filaggrin deficiency.
  • Utilizing novel murine and human experimental models.
  • Characterization of filaggrin structure and function.

Main Results:

  • Filaggrin deficiency significantly impacts skin barrier function.
  • Experimental models have enhanced understanding of filaggrin's role.
  • Direct and indirect consequences of filaggrin deficiency are increasingly understood.

Conclusions:

  • Filaggrin plays a vital role in maintaining skin homeostasis.
  • Understanding filaggrin deficiency is key to AD pathogenesis.
  • Restoring filaggrin expression presents a promising avenue for novel AD therapies.
