Factor XIII Subunit A in the Skin: Applications in Diagnosis and Treatment

Area of Science:

• Dermatology
• Cell Biology
• Biochemistry

Background:

• Factor XIII subunit A (FXIII-A) is traditionally known for its role in hemostasis.
• FXIII-A is increasingly recognized for its intracellular presence and diagnostic utility in various dermatological conditions, including inflammatory diseases and malignancies.
• The precise interpretation of dermal cell types expressing FXIII-A and the mechanisms of its accumulation remain subjects of ongoing research.

Purpose of the Study:

• To provide a comprehensive guide to the interpretation of dermal cell types expressing FXIII-A.
• To assess the mechanisms of FXIII-A accumulation in human skin under physiological and pathological conditions.
• To summarize the intracellular functions and extracellular sources of FXIII-A in the dermis, focusing on its relevance to skin homeostasis and disease.

Main Methods:

• This review synthesizes existing literature on FXIII-A.
• It analyzes studies investigating FXIII-A expression in various skin cells.
• Mechanisms of FXIII-A regulation and function in dermal contexts are assessed.

Main Results:

• FXIII-A expression is observed in diverse dermal cell types, with varying interpretations.
• Mechanisms for FXIII-A accumulation involve both endogenous production and extracellular deposition.
• FXIII-A plays a role in intracellular processes and extracellular matrix modulation within the skin.

Conclusions:

• FXIII-A is a significant factor in skin homeostasis and pathogenesis of dermatological diseases.
• Understanding FXIII-A's diverse roles offers insights into disease mechanisms.
• FXIII-A holds potential therapeutic implications for wound healing and other skin conditions.
