Interleukin-15 (IL-15) is a potent regulator of T-, B-, and natural
killer cell proliferation and displays unusually tight controls of
secretion. Even though IL-15 mRNA is constitutively expressed in
monocytes/macrophages and is upregulated by a variety of stimuli,
evidence for IL-15 cytokine secretion is only found exceptionally, eg,
conditions of pathological, chronic inflammation. This raises the
possibility that monocytes express membrane-bound IL-15 rather than
secrete it. The current study explores this hypothesis. We demonstrate
here that biologically active IL-15 is indeed detectable in a
constitutively expressed, membrane-bound form on normal human
monocytes, as well as on monocytic cell lines (MONO-MAC-6, THP-1, and
U937), but not on human T or B cells (MT4, M9, C5966, JURKAT, DAUDI,
RAJI, and Epstein-Barr virus-immortalized B-cell clones). Furthermore,
cell surface-bound IL-15 is upregulated upon interferon-
stimulation. Interestingly, monocyte/macrophage inhibitory cytokines
such as IL-4 and IL-13 fail to downregulate both constitutive and
induced cell-surface expression of IL-15. Membrane-bound IL-15 does not
elute with acetate buffer or trypsin treatment, suggesting that it is
an integral membrane protein and that it is not associated with the
IL-15 receptor complex. Finally, membrane-bound IL-15 stimulates T
lymphocytes to proliferate in vitro, indicating that it is biologically
active. These findings enlist IL-15 in the fairly small family of
cytokines for which the presence of a biologically active
membrane-bound form has been demonstrated (eg, IL-1, tumor necrosis
factor- , and IL-10) and invites the speculation that most of the
biological effects of IL-15 under physiological conditions are exerted
by the cell surface-bound form.
