Quantification of Cell Turnover in the Bovine Leukemia Virus Model

: In a perspective of a comparative virology approach, characterization of the bovine leukemia virus (BLV) model may be helpful to better understand infection by the related human T-lymphotropic virus type 1 (HTLV-1). In this paper, we first provide detailed protocols to inoculate cloned BLV proviruses into sheep or cattle. We also describe methods to quantify apoptosis ex vivo and cell turnover in vivo.
