Bcl-3 is an atypical member of the I?B family. Bcl-3 functions as a cofactor of
p50/NF-?B1 or p52/NF-?B2 homodimers in nuclei, where it modulates NF-?B-regulated
transcription in a context-dependent way. Bcl-3 has tumorigenic potential, is
critical in host defense of pathogens, and has been reported to ameliorate or
exacerbate inflammation, depending on disease model. However, cell-specific
functions of Bcl-3 remain largely unknown. Here, we explored the role of Bcl-3 in
a contact hypersensitivity (CHS) mouse model, which depends on the interplay
between keratinocytes and immune cells. Bcl-3-deficient mice exhibited an
exacerbated and prolonged CHS response to oxazolone. Increased inflammation
correlated with higher production of chemokines CXCL2, CXCL9, and CXCL10, and
consequently increased recruitment of neutrophils and CD8(+) T cells. BM chimera
experiments indicated that the ability of Bcl-3 to reduce the CHS response
depended on Bcl-3 activity in radioresistant cells. Specific ablation of Bcl-3 in
keratinocytes resulted in increased production of CXCL9 and CXCL10 and sustained
recruitment of specifically CD8(+) T cells. These findings identify Bcl-3 as a
critical player during the later stage of the CHS reaction to limit inflammation
via actions in radioresistant cells, including keratinocytes.
