In this paper, we tested a specific approach to disease prevention that could be readily translated to humans. Pertussis continues to kill ~160,000 kids annually, primarily in resource limited areas. In these areas, if a child is going to see a clinician, this will most likely to happen at birth, when they are too young to be vaccinated against pertussis or any of the other major childhood diseases. However, these children could be given an at-birth injection of purified antibodies to provide “instant immunity” to prevent disease. If engineered to remain active in the body for an extended period of time, these antibodies could protect infants for their first 4 months of life. After this critical newborn period, infants could become infected and sick, but their more mature immune systems greatly reduce the risk of severe disease, long term effects and death.


With our collaborators, we evaluated the potential for at-birth antibody prophylaxis to prevent the symptoms of pertussis infection in newborn baboons, who exhibit similar responses to infection as human infants. The day after birth, baboons were given an antibody engineered to block the effects of pertussis toxin, then infected with pertussis five weeks later. Animals who were infected became very ill while those receiving antibody were clinically normal in terms of survival, coughing and other measures of disease. 


This advance is exciting not just as a strategy to prevent pertussis but because the data support the use of antibody prophylaxis more generally to prevent specific infections in high-risk populations.

In this paper, we engineered T cell receptors (TCR), which are normally present only on the surface of T cells and bind intracellular peptides presented on the surface of a target cell, for expression as a soluble protein with an antibody Fc domain and to bind the target peptide with antibody-like nanomolar affinity. A key innovation was the use of our mammalian cell display platform for TCR engineering since TCRs are recalcitrant to expression in bacteria and yeast. Using this approach, we hope to expand the range of proteins that can be targeted by therapeutic proteins to include intracellular proteins which are not accessible to antibodies and to develop novel therapeutics able to specifically target virally infected cells.
