Abstract
Here, we present a protocol to analyze the T cell profiles of the neonatal ovine lung during respiratory syncytial virus (RSV) infection. The protocol delivers standardized multiparameter flow cytometry (FCM) analysis of CD4+, CD8+, regulatory, and γδ T cells isolated from lung, lymph nodes, and bronchoalveolar lavages (BALs). We detail the preparation of RSV and transtracheal inoculation of newborn lambs. We then describe tissue isolation and preparation of cell suspensions, followed by FCM acquisition to identify different T cell subsets. For complete details on the use and execution of this protocol, please refer to Démoulins et al. (2021).
