Modeling Infectious Disease

 

 

The Cell Therapy Core uses primary cell isolates and in vivo models to study viral and parasitic infections that pose a threat to the blood supply.  Recent work has contributed to the characterization of antibodies that inhibit Chikungunya virus infection and current work is focused on Zika virus.  We are also modeling Babesia microti paresitemia in in vivo models to help develop technology for the detection of this blood-borne parasite.
