Um modelo de rato In Vivo para ativação de células T Naïve CD4 medida, proliferação e diferenciação de células Th1 induzida pelas células dendríticas derivadas de medula óssea

Overview

This article presents a protocol for in vivo determination of na茂ve CD4 T cell activation, proliferation, and Th1 differentiation induced by GM-CSF bone marrow-derived dendritic cells. The protocol includes steps for bone marrow and T-cell isolation, dendritic cell generation, and adoptive transfer of both dendritic and T-cells.
