abstract = {The tetraspanin CD82 is a potent suppressor of tumor
metastasis and regulates several processes including signal
transduction, cell adhesion, motility, and aggregation.
However, the mechanisms by which CD82 participates in innate
immunity are unknown. We report that CD82 is a key regulator
of TLR9 trafficking and signaling. TLR9 recognizes
unmethylated cytosine-phosphate-guanine (CpG) motifs present
in viral, bacterial, and fungal DNA. We demonstrate that
TLR9 and CD82 associate in macrophages, which occurs in the
endoplasmic reticulum (ER) and post-ER. Moreover, CD82 is
essential for TLR9-dependent myddosome formation in response
to CpG stimulation. Finally, CD82 modulates TLR9-dependent
NF-κB nuclear translocation, which is critical for
inflammatory cytokine production. To our knowledge, this is
the first time a tetraspanin has been implicated as a key
regulator of TLR signaling. Collectively, our study
demonstrates that CD82 is a specific regulator of TLR9
signaling, which may be critical in cancer immunotherapy
approaches and coordinating the innate immune response to
pathogens.},
