| Outline of Final Research Achievements |
In Japan, sodium-glucose co-transporter 2 (SGLT2) inhibitors, which are used for the treatment of type 2 diabetes mellitus, have been reported to be associated with serious skin and subcutaneous disorders (SSSD). These events were suggested to be specific for the first inhibitor, ipragliflozin. This study was conducted to elucidate the mechanisms underlying the ipragliflozin-specific SSSD and establish its preventive or therapeutic strategies. Alteration of cytokine pathway by ipragliflozin was suggested in the 3-D human normal skin model consisting of fibroblasts and keratinocytes, but ipragliflozin-specific alterations were not found when fibroblasts or keratinocytes only, suggesting cell-to-cell interaction might be important for the ipragliflozin-specific SSSD. Additionally, concentrative uptake of ipragliflozin into keratinocytes was found in this study, possibly being an important factor, although the transporter remained unclear.
