General strategy for broadening adenovirus tropism.
In spite of its broad host range, adenovirus type 5 (Ad5) transduces a number of clinically relevant tissues and cell types inefficiently, mostly because of low expression of the coxsackievirus-adenovirus receptor (CAR). To improve gene transfer to such cells, we modified the Ad5 fiber knob to recognize novel receptors. We expressed a functional Ad5 fiber knob domain on the capsid of phage lamb...
متن کاملCancer-targeting gene therapy using tropism-modified adenovirus.
Gene therapy has the potential to provide highly selective, curative cancer treatments without inducing systemic toxicity. Adenoviral vectors have been extensively used for cancer gene therapy because of their relatively high efficacy of gene transfer. However, gene transduction to cancer cells is limited by the necessity of using adenoviral type 5 vectors. This is because these vectors have a ...
متن کاملTreatment of ovarian cancer with a tropism modified oncolytic adenovirus.
Ad5-Delta 24RGD is an adenovirus that is selectively replication competent in cells defective in the Rb/p16 pathway, such as ovarian cancer cells. The fiber of Ad5-Delta 24RGD contains an integrin binding RGD-4C motif, allowing Coxsackie adenovirus receptor-independent infection of cancer cells. Oncolysis of cell lines was similar to that of a wild-type control, and replication in primary tumor...
متن کاملA phase I study of a tropism-modified conditionally replicative adenovirus for recurrent malignant gynecologic diseases.
PURPOSE To determine the maximum tolerated dose (MTD), toxicity spectrum, clinical activity, and biological effects of the tropism-modified, infectivity-enhanced conditionally replicative adenovirus (CRAd), Ad5-Δ24-Arg-Gly-Asp (RGD), in patients with malignant gynecologic diseases. EXPERIMENTAL DESIGN Cohorts of eligible patients were treated daily for 3 days through an i.p. catheter. Vector ...
متن کاملHer2-specific multivalent adapters confer designed tropism to adenovirus for gene targeting.
Adenoviruses (Ads) hold great promise as gene vectors for diagnostic or therapeutic applications. The native tropism of Ads must be modified to achieve disease site-specific gene delivery by Ad vectors and this should be done in a programmable way and with technology that can realistically be scaled up. To this end, we applied the technologies of designed ankyrin repeat proteins (DARPins) and r...
