Photodynamic opening of blood-brain barrier #MMPMID29188101Semyachkina-Glushkovskaya O; Kurths J; Borisova E; Sokolovski S; Mantareva V; Angelov I; Shirokov A; Navolokin N; Shushunova N; Khorovodov A; Ulanova M; Sagatova M; Agranivich I; Sindeeva O; Gekalyuk A; Bodrova A; Rafailov EBiomed Opt Express 2017[Nov]; 8 (11): 5040-8 PMID29188101show ga
Photodynamic treatment (PDT) causes a significant increase in the permeability of the blood-brain barrier (BBB) in healthy mice. Using different doses of laser radiation (635 nm, 10-40 J/cm2) and photosensitizer (5-aminolevulinic acid ? 5-ALA, 20 and 80 mg/kg, i.v.), we found that the optimal PDT for the reversible opening of the BBB is 15 J/cm2 and 5-ALA, 20 mg/kg, exhibiting brain tissues recovery 3 days after PDT. Further increases in the laser radiation or 5-ALA doses have no amplifying effect on the BBB permeability, but are associated with severe damage of brain tissues. These results can be an informative platform for further studies of new strategies in brain drug delivery and for better understanding of mechanisms underlying cerebrovascular effects of PDT-related fluorescence guided resection of brain tumor.�
