TLDR Mitochondrial dysfunction may contribute to chronic inflammation and immune system issues in Lichen planopilaris.
The study explored the role of mitochondrial dysfunction in the development of Lichen planopilaris (LPP), a form of scarring alopecia. It found that Mitochondrial transcription factor A was down-regulated in LPP hair follicles, while functional markers MT-CO1 and VDAC1 were upregulated, suggesting that mitochondria were overactive despite issues with genome replication. These findings indicate that a metabolic switch to mitochondrial respiration in LPP may lead to chronic inflammation and loss of immune privilege, potentially due to excess ATP production and the release of damage-associated molecular patterns. This points to mitochondrial dysfunction as a possible underlying mechanism in LPP and potentially other autoimmune diseases. The exact number of samples analyzed was not mentioned.
