Abstract
This invention relates generally to compositions for making anellovectors and uses thereof. For instance, a method herein can comprise providing a nucleic acid construct that comprises a first Anellovirus genome encoding an exogenous effector and a second Anellovirus genome or fragment thereof, arranged in tandem. In some embodiments, the nucleic acid construct results in production of an anellovector comprising an Anellovirus genetic element encoding the exogenous effector, enclosed in a proteinaceous exterior.
Claims10
A nucleic acid (e.g., DNA) construct comprising:
- a) a first Anellovirus genome comprising a sequence encoding an exogenous effector;
- b) a second Anellovirus genome or fragment thereof, placed in tandem with the first Anellovirus genome;
- and
- c) optionally, a spacer sequence situated between (a) and (b).
The nucleic acid construct of any of the preceding claims, wherein the second Anellovirus genome or fragment thereof has a length of less than 2800, 2700, 2600, 2500, 2000, 1500, 1000, 900, 800, 700, 600, or 500 nucleotides.
The nucleic acid construct of any of the preceding claims, wherein the second Anellovirus genome or fragment thereof is positioned 3′ relative to the first Anellovirus genome.
The nucleic acid construct of any of the preceding claims, wherein the second Anellovirus genome or fragment thereof is positioned 5′ relative to the first Anellovirus genome.
The nucleic acid construct of any of the preceding claims, wherein the nucleic acid construct comprises the spacer sequence.
The nucleic acid construct of any of the preceding claims, wherein the nucleic acid construct does not comprise the spacer sequence.
A method of manufacturing an anellovector comprising a genetic element enclosed in a proteinaceous exterior, comprising:
- a) providing a cell (e.g., a mammalian host cell) comprising the nucleic acid construct of any of the preceding embodiments and one or more copies of the Anellovirus genetic element (e.g., wherein the Anellovirus genetic element was amplified from the nucleic acid construct);
- b) incubating the cell under conditions that allow the Anellovirus genetic element to be enclosed in a proteinaceous exterior in the cell;
- thereby manufacturing the anellovector.
