A novel type of influenza A virus-derived Defective interfering Particle for antiviral therapy

Ref.-Nr.: 1402-5459-BC

Research Tools : Antibodies

Human influenza A virus (IAV) is responsible for seasonal disease in people and can cause worldwide pandemics. The main lines of defense against IAV are vaccines and antiviral drugs.

Influenza vaccines, including killed and live vaccines, recombinant virus-like particles and viral particles, have been available commercially for many years. Typically, the composition of influenza vaccines is based on the major influenza virus strains causing infection in the previous season. Accordingly, ...

Nucleic Acid-, Protein and Cell-related Technologies

The RNA-programmable DNA-endonuclease Cas9 is widely used for genome engineering, where a high degree of specificity is required. Though this is a mechanism well controlled by canonical base-pairing, there is evidence that Cas9 does accept mismatches under certain circumstances.
This might be seen as a threat to precision needed in genome engineering at least in environments where such high precision is ultimately needed and acceptance of mismatches needs to be avoided, e.g.: cellular gene ...

Genome-Editing-Technologies - Single compound or compound mix dramatically improve Homology-Directed-Repair (HDR)

Precise genome editing demands for homology-directed repair (HDR) by aiming to introduce a new double stranded DNA substituting for a homologous sequence but partially defect one. This substrate dependent reaction does compete with direct non-homologous end joining (NHEJ) of the double strand breaks. NHEJ is error-prone and is therefor mainly used for gene inactivation.
The rate of NHEJ is directly limiting the rate of HDR. For this reason HDR in vitro does occur on a very low level only and ...

Nucleic Acid-, Protein and Cell-related Technologies

A Cas nuclease such as Cas9 can introduce a DNA double strand break in a sequence target that is complementary to a 20-nt spacer sequence of its bound guide RNA (gRNA) when a protospacer adjacent motif (PAM) is present. The gRNA can be provided as duplex of spacer containing CRISPR RNA (crRNA) and trans-activating crRNA (tracrRNA). Or as a single gRNA (sgRNA) where crRNA and tracrRNA are fused by an artificial loop.
Hence a gRNA consists of the target-specific spacer and a constant part typically ...

Proteins are the main functional units within cells. Their regulated synthesis and degradation are crucial for controlling biological processes. In all cells, protein synthesis is used to respond to extra- and/or intracellular cues to remodel cellular function. Previous studies probing the role of protein synthesis have used chemical inhibitors, often common antibiotics, which are effective but lack functional and cell-type specificity when applied to a mixture of cells.
