Adenovirus Vp Helper

Adenovirus VP helper is a helper-virus system that supplies adenoviral functions needed to produce or amplify a dependent viral vector, commonly recombinant adeno-associated virus (AAV). During production, helper-derived genes provide regulatory and replication-support proteins, while vector components direct genome packaging into capsids, separating these functions from the therapeutic genome. In immunology and infection research, this approach enables controlled generation of viral vectors for gene delivery, vaccine development, and immune-response studies. It also supports investigation of adenovirus-host interactions while helping researchers evaluate vector yield, purity, and functional activity.

Cited by 8 •

2012

Here we describe a protocol based only on cell infection, which improves the efficiency of recombinant parvovirus production by more than 100 fold in comparison to other protocols in use. This protocol relies on the use of a novel adenovirus 5-based helper containing the parvovirus VP transcription unit (Ad-VP).

A protocol for generation of high-capacity adenoviral vectors lacking all viral coding sequences is presented. Cloning of transgenes contained in the vector genome is based on homing endonucleases. Virus amplification in producer cells grown as adherent cells and in suspension relies on a helper virus providing viral genes in trans.

2012

We describe hepatic neo-islet formation in STZ (streptozotocin)-induced diabetic mice by gene transfer of Neurogenin3 (Ngn3) and Betacellulin (Btc) using helper-dependent adenoviral vector (HDAd) and the reversal of hyperglycemia. Our method takes advantages of helper-dependent adenoviral vectors with their highly efficient in vivo transduction and the long lasting gene expression.

Source: Chen, H., et al. Live Cell Imaging of the TGF-β/Smad3 Signaling Pathway In Vitro and In Vivo Using an Adenovirus Reporter System. J. Vis. Exp. (2018).This video demonstrates a method to study SMAD pathway activation in breast cancer cells using dual adenoviral infection. One virus delivers a constitutively expressed GFP gene, while the other carries an RFP reporter under a SMAD-sensitive promoter. Upon TGF-beta stimulation, SMAD proteins are activated, forming a complex that induces RFP...

Immunological Synapse Formation Between Helper T Cells and Antigen-Presenting Cells

This video demonstrates the in vitro study of immunological synapse formation between an antigen-presenting cell and helper T lymphocytes using a fluorescence microscope. T cell receptors of helper T lymphocytes interact with an antigen-MHC-II complex in antigen-presenting cells and form immunological synapses, followed by secretory vesicle movements toward the synapse, which is visualized by fluorescent microscopy.
