Dual-Surface Modified Virus Capsids for Targeted Delivery of Photodynamic Agents to Cancer Cells
Abstract
Bacteriophage MS2 was used to construct a targeted, multivalent photodynamic therapy vehicle for the treatment of Jurkat leukemia T cells. The self-assembling spherical virus capsid was modified on the interior surface with up to 180 porphyrins capable of generating cytotoxic singlet oxygen upon illumination. The exterior of the capsid was modified with ∼20 copies of a Jurkat-specific aptamer using an oxidative coupling reaction targeting an unnatural amino acid. The capsids were able to target and selectively kill more than 76% of the Jurkat cells after only 20 min of illumination. Capsids modified with a control DNA strand did not target Jurkat cells, and capsids modified with the aptamer were found to be specific for Jurkat cells over U266 cells (a control B cell line). The doubly modified capsids were also able to kill Jurkat cells selectively even when mixed with erythrocytes, suggesting the possibility of using our system to target blood-borne cancers or other pathogens in the blood supply.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
