What is Lentivirus

Lentivirus Protocol Download Lentivirus (lente-, Latin for “slow”) is a genus of retroviruses, causing chronic and deadly diseases by long incubation periods in human or other mammalian species [1]. The virion is a medium-sized (80-100nm) and enveloped, slightly pleomorphic, spherical with an isometric nucleocapsid containing two copies of positive-sense ssRNA genome. Most lentiviral vectors are […]

Recombinant Lentivirus System

Lentivirus Protocol Download a) Introduction of recombinant lentivirus vector system Since wild-type HIV-1 based lentivirus is associated with destruction of host immune system, especially CD4+ helper T lymphocytes, multiple generations of lentivirus vectors have been designed with enhanced safety features and as attractive vectors for gene therapy. To date, there have been three generations of […]

Life Cycle of Lentivirus

Lentivirus Protocol Download The life cycle of HIV-1 starts with viral entry, in which process the virus binds to the CD4 receptor or a coreceptor (CCR5 or CXCR4) with gp120 protein, thereby anchoring itself onto host cell surface, allowing fusion between the cellular and viral membranes. After entry into the cell, the viral nucleoprotein together […]

Lentivirus Genome Structure and Virus Assembly

Lentivirus Protocol Download Lentivirus, as represented by HIV-1, is a medium-sized (80-100nm) and enveloped, slightly pleomorphic, spherical virus with an isometric nucleocapsid (Figure1A). Unlike other retroviruses, HIV-1 is featured by a set of additional regulatory and accessory genes [11,12]. Its DNA genome, transcribed from HIV-1 ssRNA, is approximately 9.7 kb and contains 9 ORFs. Besides […]

Advantages and Drawbacks of Lentivirus Vector-mediated Gene Delivery

Lentivirus Protocol Download a) Advantages of lentivirus -mediated gene delivery Lentivirus has been developed as an attractive candidate for creating viral vectors for gene therapy due to various advantages.1) Customized cloning for any other gene ORF expression, shRNA/miRNA and CRISPR/Cas9.2) No known immunogenic proteins generated.3) High titer. 108TU/ml or 109TU/ml lentiviral titer for cell line […]

Lentivirus Gene Therapy

Lentivirus Protocol Download Lentivirus has been proved as an excellent gene therapy vector. To date, more than 236 clinical trials have been carried out using lentivirus vectors for gene delivery [4], and promising gene therapy outcomes from recombinant lentivirus have been achieved from clinical trials for a great number of diseases (Table 1), especially for […]
