Description:
Upon infection, antigen-specific CD8(+) T lymphocyte responses display a highly reproducible pattern of expansion and contraction that is thought to reflect a uniform behavior of individual cells. We tracked the progeny of individual mouse CD8(+) T cells by in vivo lineage tracing and demonstrated that, even for T cells bearing identical T cell receptors, both clonal expansion and differentiation patterns are heterogeneous. As a consequence, individual naive T lymphocytes contributed differentially to short- and long-term protection, as revealed by participation of their progeny during primary versus recall infections. The discordance in fate of individual naive T cells argues against asymmetric division as a singular driver of CD8(+) T cell heterogeneity and demonstrates that reproducibility of CD8(+) T cell responses is achieved through population averaging.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gerlach, Carmen -- Rohr, Jan C -- Perie, Leila -- van Rooij, Nienke -- van Heijst, Jeroen W J -- Velds, Arno -- Urbanus, Jos -- Naik, Shalin H -- Jacobs, Heinz -- Beltman, Joost B -- de Boer, Rob J -- Schumacher, Ton N M -- New York, N.Y. -- Science. 2013 May 3;340(6132):635-9. doi: 10.1126/science.1235487.
