Inducción de la inflamación intestinal por transferencia adoptiva de células T CD4+ transgénicas CBir1 TCR a ratones inmunodeficientes

Overview

This protocol describes a gut microbiota antigen-specific T cell adoptive transfer colitis model. CD4 + T cells from CBir1 TCR transgenic mice are transferred into Rag1 -/- mice, inducing intestinal inflammation.
