Aminolevulinic acid photodynamic therapy (ALA-PDT) represents a safe and effective therapeutic option for cutaneous M. marinum infections, particularly in drug-resistant cases. This report describes a patient with cutaneous granuloma caused by M. marinum infection who showed no significant improvement after two months of oral triple-antibiotic therapy. Subsequently, while continuing oral antibiotics, the patient underwent ALA-PDT once weekly for 4 consecutive weeks. Following four treatment sessions, the nodules, plaques, and ulcers on both the wrist and forearm were completely eradicated, with no recurrence observed during the 6-month follow-up period.

Emerging evidence suggests that cordycepin can synergize with other therapeutic modalities. Therefore, we investigated whether the combination of PDT and cordycepin could enhance the therapeutic efficacy. Using colony formation assay and flow cytometry, we assessed the effects of the viability and apoptosis on EC cells. RT-qPCR and Western blot analyses were employed to examine the expression of pathway-related proteins and genes. In vitro, results demonstrated that the combination of PDT and cordycepin enhanced apoptosis to inhibit cell growth and increased the production of immune factors IL-18 and IL-1β. Furthermore, it inhibited the expression levels of p-PI3K/PI3K, p-AKT/AKT, and Bcl-2, while enhancing the expression levels of FOXO3, Caspase-3, Bax, Caspase-9, and Cyt-C. In conclusion, PDT combined with cordycepin enhances the anti-cancer effect through the PI3K/AKT/FOXO3 signaling pathway in EC cells.
