CD27 and colitis: RNA sequencing analysis demonstrated a significant upregulation of genes associated with inflammation and immune responses in MLB cells from colitis rats, particularly key molecules involved in T cell activation, such as cluster of differentiation 27 (Cd27) and cluster of differentiation 40 (Cd40), and the chemotactic receptor C-C motif chemokine receptor 8 (Ccr8), which mediates B cell migration in response to T cells.
