Abstract

Key PointsExpression of exhaustion markers is decreased on CMV-specific CD8+ T cells from CLL patients as compared with those from age-matched HCs. Functionality of CMV-specific CD8+ T cells in CLL with respect to cytokine production, cytotoxicity, and immune synapse formation is preserved.
