Intracellular storage of CD26 in cytotoxic effector lymphocytes. Co-localization of intracellular CD26 with (A) the lysosomal and degranulation marker protein CD107a (Lamp-1) in CD4+/TCR αβ+, CD8+/TCR αβ+, CD3+/TCR γδ+, and CD3/CD56+ cells and (B) the cytotoxic effector proteins granzyme A (GrzA), granzyme B (GrzB), perforin (Prf), and granulysin (Gnly) in CD3+/TCR γδ+ cells.
