Outline of Final Research Achievements

In the present study, first, in experiments using cells, it was clarified that the membrane permeability of cisplatin is enhanced when the inflammatory cytokines TNF-α and IL-1β coexist. This suggests that the blood concentration of cisplatin may be affected by inflammatory cytokines. Next, human serum was used to examine changes in inflammatory cytokines during chemotherapy including platinum. Inflammatory cytokines peaked around 2 weeks after administration regardless of the chemotherapy regimen. These results suggest that inflammatory cytokines may be altered by chemotherapy, and as a result, vascular permeability of cisplatin may be enhanced.

Academic Significance and Societal Importance of the Research Achievements

プラチナを含むがん化学療法により炎症性サイトカインが変動し、これによりプラチナ製剤の血管透過性が亢進する可能性が示唆された。
このことから、炎症によってプラチナ製剤の細胞内への取り込み量が増加することが、神経障害が発現する要因の1つである可能性が示唆された。今後、血管透過性の亢進によるヒト神経細胞におけるプラチナ製剤の取り込み量の変動に関して更なる検討を行い、抗がん剤による神経障害の発現機序の解明に努めたい。
