Fatty Acid Receptor CD36 May Play Key Role in Psoriasis Skin Inflammation

New research reveals how a specific protein involved in fat transport might contribute to psoriasis development, suggesting potential treatment targets.

A newly published study in the Journal of Investigative Dermatology has identified a potentially important mechanism behind the skin inflammation seen in psoriasis, offering hope for future treatment approaches.

Researchers have found that a protein called CD36, which helps transport fatty acids into cells, appears significantly elevated in the skin lesions of patients with psoriasis. According to the study, the levels of this protein positively correlated with disease severity, suggesting it might play a direct role in the inflammatory process.

The Connection Between Fat Transport and Skin Inflammation

Psoriasis is characterized by altered fat metabolism in the skin and dysfunction of keratinocytes (the main cells in the outermost skin layer). While CD36 has been linked to various inflammatory conditions through its regulation of lipid metabolism, its specific role in psoriasis has remained poorly understood until now.

The research team discovered that when CD36 was selectively removed from keratinocytes in mice, the animals showed reduced psoriasis-like inflammation when exposed to imiquimod, a compound commonly used to induce psoriasis-like conditions in laboratory studies.

Potential Treatment Implications

Further supporting CD36's role, the researchers found that topical treatment with sulfosuccinimidyl oleate, which blocks CD36 function, also resulted in visibly reduced skin inflammation in the experimental models.

This discovery adds to our understanding of how altered fat processing in skin cells may contribute to the persistent inflammation seen in psoriasis. While this research is preliminary, it identifies CD36 as a potential target for future psoriasis treatments that might address the underlying metabolic aspects of the condition rather than just suppressing symptoms.

For people with albinism who also have psoriasis, these findings could be particularly relevant, as managing inflammatory skin conditions becomes even more important when the skin already requires special care and protection.
