Inflammation and Exosomes in Fabry Disease Pathogenesis.

Area of Science:

• Immunology
• Genetics
• Cell Biology

Background:

• Fabry Disease (FD) is a prevalent lysosomal storage disorder caused by GLA gene mutations.
• Gb-3 accumulation in lysosomes impairs cellular functions, particularly in immune cells.
• Evidence suggests FD triggers pro-inflammatory mediator production, leading to acute and potentially chronic inflammation.

Purpose of the Study:

• To review the association between Fabry Disease and immune response alterations.
• To explore the role of extracellular vesicles (EVs) as potential inflammatory mediators in FD.

Main Methods:

• Literature review of existing research on Fabry Disease, immune responses, and extracellular vesicles.
• Synthesis of evidence linking Gb-3 accumulation to inflammation.
• Analysis of the proposed function of EVs in mediating inflammatory processes in FD.

Main Results:

• Gb-3 accumulation in FD potentiates pro-inflammatory mediator production.
• An acute inflammatory process is evident in FD, potentially becoming chronic.
• Extracellular vesicles (EVs) are identified as intercellular communicators with the capacity to transport inflammatory cargo.

Conclusions:

• Fabry Disease significantly impacts immunological responses.
• Extracellular vesicles (EVs) are implicated as potential vehicles for inflammation in FD, transporting cytokines and immunomodulatory molecules.
