Interleukin-2

Interleukin-2, IL-2 (bahasa Inggris: T Cell Growth Factor, TCGF, lymphokine) adalah sejenis sitokina yang disebut hormon leukositotropik,^[4] yang berperan sebagai stimulan dalam proliferasi sel B dan sel T.^[5]

IL-2 ditelisik mempunyai fungsi yang serupa dengan IL-15.^[6] IL-2 berperan dalam apoptosis sel T yang teraktivasi bukan oleh antigen, hal ini penting untuk mencegah autoimunitas, sedangkan IL-15 berperan dalam pemeliharaan sel T memori.^[6]
