Influenza is a highly contagious, acute viral respiratory disease that occurs seasonally in most parts of the world. The infection resides primarily in the respiratory tract (nose, throat and bronchi), but causes both local and systemic symptoms including fever, chills, cough, headache, myalgia, sore throat, and malaise. Influenza-related pneumonia is the main complication of infection. Annual epidemics cause significant morbidity and mortality worldwide. Each year, influenza infections result in an average of 110,000 hospitalizations, approximately 20,000 of which result in death. These deaths are heavily concentrated (>90%) among persons who are at highest risk for influenza-related complications — elderly adults (over 65), children under age five, patients with pre-existing respiratory or cardiovascular disease, and women in the third trimester of pregnancy. Thus, the prevention of influenza virus infection is a major public health priority…

The Sf-9 insect cell/baculovirus expression system is one of the most commonly used protein expression systems. It is the preferred system for generating large amounts of protein in a short period of time, and it has been successfully used to express several hundreds of different proteins. A representative list of the different proteins made in our laboratory over the past decade with the Sf-9 insect cell/BEVS system is given in Table 1. These proteins are often used in drug screening studies and structure function analysis. Proteins intended for therapeutic purposes are not normally produced using this technology, although a few examples do exist. There is also an unexplored potential for the cells to be used for the production of recombinant viral vectors. Recent reports demonstrating the ability of baculoviruses to express proteins in mammalian cells, with mammalian promoters, indicate that BEVS technology might soon have a major role to play in the field of gene delivery…
