TRAF6 deficiency leads to osteopetrosis and impaired signaling of interleukin-1 (IL-1), CD40, and lipopolysaccharide (LPS). TRAF6 is essential for perinatal and postnatal survival, bone metabolism, and signaling pathways involving IL-1, CD40, and LPS. TRAF6-deficient mice exhibit osteopetrosis, characterized by increased bone density, failure of tooth eruption, and defective osteoclast function. These mice also show impaired responses to LPS and have defects in IL-1 and CD40 signaling. TRAF6 is involved in the signaling pathways of IL-1, CD40, and LPS, and its absence leads to defects in NF-κB activation and JNK/SAPK signaling. TRAF6 is required for the proper function of osteoclasts, which are essential for bone resorption and remodeling. The study highlights the critical role of TRAF6 in various physiological processes, including bone metabolism and immune signaling.TRAF6 deficiency leads to osteopetrosis and impaired signaling of interleukin-1 (IL-1), CD40, and lipopolysaccharide (LPS).
