Galectin-3 is a member of a growing family of
ß-galactoside-binding animal lectins. Previous studies have
demonstrated a variety of biological activities for this protein
in vitro, including activation of cells,
modulation of cell adhesion, induction of pre-mRNA
splicing, and regulation of apoptosis. To assist in fully
elucidating the physiological and pathological functions of this
protein, we have generated galectin-3-deficient
(gal3-/-) mice by targeted interruption of the galectin-3
gene. Gal3-/- mice consistently developed fewer
inflammatory cell infiltrations in the peritoneal cavities than the
wild-type (gal3+/+) mice in response to thioglycollate
broth treatment, mainly due to lower numbers of macrophages.
Also, when compared to cells from gal3+/+
mice, thioglycollate-elicited inflammatory cells from
gal3-/- mice exhibited significantly lower levels of
NF-
B response. In addition, dramatically different
cell-spreading phenotypes were observed in cultured macrophages from
the two genotypes. Whereas macrophages from gal3+/+ mice
exhibited well spread out morphology, those from
gal3-/- mice were often spindle-shaped. Finally,
we found that peritoneal macrophages from gal3-/- mice
were more prone to undergo apoptosis than those from
gal3+/+ mice when treated with apoptotic stimuli,
suggesting that expression of galectin-3 in inflammatory cells may lead
to longer cell survival, thus prolonging inflammation. These
results strongly support galectin-3 as a positive regulator of
inflammatory responses in the peritoneal cavity.
