Южнокорейские ученые wrote:Although the selective replication and spread of oncolytic adenoviruses within cancer cells and tissues has had some success as an anticancer treatment, its promise has been limited because of the uneven penetration and distribution of these viruses in tumor tissues. To date, ONYX-015, an oncolytic adenovirus in which the E1B 55-kDa gene has been deleted, has been administered to more than 300 cancer patients with various tumor types (1,2) but has had only limited success (i.e., local tumor regression rates of 0%–14%). Sauthoff et al. (3) demonstrated that high levels of adenoviruses persisted in xenograft tumors for at least 8 weeks after intratumoral injection of wild-type adenoviruses, but the viral distribution pattern in the tumor tissue was uneven and patchy. Harrison et al. (4) detected a high level of viruses in persistent viable tumors up to 100 days after the initial viral injection. Thus, despite long-term viral persistence in tumors, the limited spread of virus to cells throughout the tumor could explain the low response rates observed.

О! Это очень интересно.bulochka, не просветите, насколько это перспективно и несет ли серьезные шансы на полную и окончательную победу?
