Objective:
Psoriasis, a common chronic
inflammatory skin condition with genetic underpinnings, is traditionally
managed with cupping therapy. Although used historically, the precise
mechanical effects and therapeutic mechanisms of cupping in psoriasis
remain largely unexamined. This study aimed to evaluate cupping
therapy’s efficacy for psoriasis and investigate its role in modulating
inflammatory responses and cellular metabolism.
Methods:
Psoriasis
was induced in mice using topical imiquimod (IMQ). The effects of
cupping on psoriatic lesions were assessed using the Psoriasis Area and
Severity Index score, histology, immunohistochemistry, and
immunofluorescence staining. polymerase chain reaction sequencing
(RNA-seq) and Western blotting were conducted to examine changes in mRNA
expression and the AMP-activated protein kinase (AMPK) signaling
pathway.
Results:
Cupping therapy
significantly reduced inflammation, epidermal thickness, and
inflammatory cell infiltration in mice with IMQ-induced psoriasis.
Immunohistochemistry and immunofluorescence showed lower expression of
inflammatory markers and a shift in T-cell populations. RNA-seq and
Western blotting indicated that cupping upregulated Piezo1 and activated
the AMPK pathway, improving energy metabolism in psoriatic skin.
Conclusion:
Cupping
therapy reduces epidermal hyperproliferation and inflammation in
psoriasis, rebalancing the local immune microenvironment.
Mechanistically, cupping promotes calcium influx via Piezo1, activates
AMPK signaling, and supports metabolic homeostasis, suggesting
therapeutic potential for psoriasis.
