Adeno-Associated Virus(AAV) Gene Therapy Landscape

Adeno-Associated Virus(AAV) Gene Therapy Landscape Adeno-associated viruses (AAV) are virus particles composed of single-stranded DNA surrounded by a protein shell. Despite their simple structure, recombinant AAVs (rAAV) can perform the important role of delivering nucleic acids into cells during gene therapy. Due to the high demand for potentially curative treatments in areas of huge unmet […]

Viral vector-based vaccines: Lentiviral vector-based vaccines

COVID-19 vaccine development protocol: PSV Based Neutralization Assay Lentivirus (lente-, Latin for “slow”) is a genus of retroviruses, medium sized (80-100nm) and enveloped, slightly pleomorphic, spherical with an isometric nucleocapsid containing two copies of positive-sense ssRNA genome (Fig. 11A). Most lentiviral vectors are based on the Human Immunodeficiency Virus (HIV), which causes AIDS, a chronic […]

Viral vector-based vaccines: Adenovirus (AdV) vector-based vaccines

COVID-19 vaccine development protocol: PSV Based Neutralization Assay Adenovirus (AdV) vector-based vaccines Adenovirus (AdV) is a member of the family Adenoviridae, whose name derives from their initial isolation from human adenoids in 1953 [42]. It is a medium sized (90-100nm) and non-enveloped virus with an icosahedral nucleocapsid containing a 36kb double stranded DNA genome (Fig. […]

Viral vector-based vaccines: AAV vector-based vaccines

COVID-19 vaccine development protocol: PSV Based Neutralization Assay Viral vector-based vaccines Viral vector-based vaccines are vaccines that can deliver specific antigen gene to target cells based on the infection ability of viruses, produce antigens via the nutrition substances in host cells, and then provoke immune responses with the newly synthesized antigens. Compared with the traditional […]

Advantages and drawbacks of AAV vector-mediated gene transfer

AAV protocol Download Adeno Associated Virus (AAV)  a) Advantages of AAV-mediated gene transferAAV has been developed into a very attractive candidate for creating viral vectors for gene therapy and the creation of isogenic human disease models due to various advantages. 1) Superior biosafety rating. The wild type AAV has not currently been known to cause […]

AAV Gene Therapy Review

AAV protocol Download Adeno Associated Virus (AAV)  AAV has been proved as the most excellent gene therapy vector. To date, more than 204 clinical trials have been carried out using AAV vectors for gene delivery [4], and promising gene therapy outcomes have been achieved from Phase 1, Phase 2 and Phase 3 trials for a […]

What is Adeno-associated virus (AAV) vector?

AAV protocol Download Adeno Associated Virus (AAV) Adeno-associated virus (AAV) is a small-single strand DNA virus, member of human parvovirus, originally described in the 1960s by Bob Atchison at Pittsburgh and Wallace Rowe at NIH as a contaminant in preparation of adenovirus [1,2]. Shortly after its discovery, AAV was then isolated from humans, but serological studies […]
