Model | Deletion timing | Treatment timing | Treatment response | Ref |
---|---|---|---|---|
Tsc1 induced KO | 2–4 months postnatal | Rapamycin after seizure onset | Prolonged survival; no seizures during treatment | [49] |

Tsc1 GFAP KO | Embryonic | Rapamycin treatment started at P14 | No seizures developed; prolonged survival during treatment | [37] |
Tsc1 GFAP KO | Embryonic | Rapamycin treatment as juvenile (6 week) | No seizures developed; prolonged survival during treatment | [37] |
Tsc1 nestin KO | Embryonic | Rapamycin treatment started at P8 | No seizures developed; prolonged survival during treatment | [39] |
