Serum Semaphorin Alterations in Psoriasis: Links to Metabolic Status Rather than Disease Severity

Psoriatic patients exhibited distinct alterations in circulating semaphorins, with significantly increased serum Sema3A, Sema3E and Sema4D, and reduced Sema4A and Sema7A compared with healthy subjects. Selected semaphorins demonstrated associations with metabolic parameters and patient characteristics, although none can serve as marker of disease severity. The findings indicate that semaphorins may reflect psoriasis-related systemic disturbances, but further studies are required to explore their potential with disease-associated metabolic or clinical profiles.
