Summary
Junctional epidermolysis bullosa type Herlitz (JEB-H) is a severe genetic skin disorder causing widespread blistering at birth. Caused by mutations in laminin-332 genes, it has high mortality, necessitating early diagnosis and care.
Area of Science:
- Genetics
- Dermatology
- Molecular Biology
Background:
- Junctional epidermolysis bullosa type Herlitz (JEB-H) is a severe, autosomal recessive variant of epidermolysis bullosa.
- It is characterized by generalized, extensive mucocutaneous blistering at birth and often leads to early lethality.
- JEB-H is primarily caused by homozygous null mutations in LAMA3, LAMB3, or LAMC2 genes, which encode for laminin-332 chains.
Purpose of the Study:
- To outline the epidemiology, clinical presentation, and diagnostic approaches for JEB-H.
- To highlight the high morbidity and mortality associated with this condition.
- To discuss the current and future therapeutic perspectives for JEB-H.
Main Methods:
- Review of epidemiological data on JEB-H.
- Analysis of clinical presentation and diagnostic criteria.
- Evaluation of current management strategies and future therapeutic options, including gene therapy.
Main Results:
- JEB-H presents as a severe and clinically diverse mechanobullous genodermatosis.
- High rates of morbidity and mortality are observed in affected individuals.
- Genetic mutations in laminin-332 genes are the primary cause.
Conclusions:
- Optimized protocols for early diagnosis, including prenatal testing, and palliative care are crucial for managing JEB-H.
- Gene therapy represents the most promising future therapeutic avenue for JEB-H.

01:05Desmosomes
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 complexes comprising desmosomal...
01:19Clinical Applications of Epidermal Stem Cells
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 EpiSCs...
01:29Tight 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...
01:11Papillary Dermis
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

01:12Renewal of Skin Epidermal Stem Cells
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
01:02Long-patch Base Excision Repair
Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
