Gene transfer into neural cells in vitro using adenoviral vectors.

Adenoviruses (Ads) have become a very attractive and versatile vector system for delivering genes into brain cells in vitro and in vivo. One of the main attractions of Ads is that they can mediate gene transfer into post-mitotic cells, i.e. neurons. Ads are easy to grow and manipulate, stable, and their biology is very well understood. This unit is designed to help newcomers into the field, to design, prepare and grow replication-defective recombinant adenovirus vectors with the aim of transferring genes into neurons and glial cells in primary culture. It provides step-by-step methods describing the preparation of brain cell cultures, their infection using recombinant adenovirus vectors and also the assessment of transgene expression using a variety of techniques including fluorescence immunocytochemistry and fluorescence activated cell-sorting (FACS) analysis. The methods described will be useful to scientists wishing to enter the adenovirus field to construct adenovirus vectors to be used for gene transfer into neural cells.
