Az imikimod, az imidazol-kinolin-aminok családjába tartozó, kis, szintetikus, nukleotidszerű molekula. Ismert immunválasz-módosító, vírusellenes és tumorellenes hatása, amelyet a Toll-like receptorok (TLR7 és TLR8) közvetítenek. Az imikimod főként a TLR7-et kifejező plazmacitoid dendritikus sejteket és a Langerhans-sejteket célozza meg, és csak másodlagosan vesz részt egyéb gyulladásos sejtek aktiválásában. A TLR7 stimulációjakor indukálódó jelátviteli mechanizmusok mind a veleszületett, mind a szerzett immunrendszert aktiválják, különös tekintettel a sejt által közvetített immunreakciókra. Az 5%-os imikimodkrém (Aldara, MEDA Pharma) lokális alkalmazása hatékonynak bizonyult az aktinikus keratosisok, a superficialis basaliomák és a külső nemi szerveken és perianalisan elhelyezkedő condylomák kezelésében. Az imikimod különösen alkalmas kiterjedt, látszólag tünetmentes, de daganatsejteket tartalmazó mezők („field cancerization”) kezelésére. A beteg által alkalmazott otthoni kezelés kiváló kozmetikai eredményt ad. Irodalmi adatok utalnak továbbá az imikimod hatékonyságára nodularis basalioma és egyéb, nem melanomatípusú bőrdaganat kezelésében. Az imikimod lokális alkalmazása jól tolerálható, a krém az alkalmazás helyén enyhe vagy közepesen súlyos gyulladásos reakciót okozhat. Ez a dolgozat átfogó képet ad az imikimod alkalmazásával kapcsolatos eddigi tapasztalatokról és a potenciális jövőbeli felhasználási lehetőségekről.
