Research Interest
Determining the mechanism by which Measles virus nucleocapsid protein (MVNP) results in aberrant osteoclast differentiation. MVNP has been shown to be able to induce a Pagetic phenotype when transduced into osteoclast precursors and there is increasing evidence that it can play a role in the development of Paget’s disease. We have reported that MVNP signals through the IKK family member TBK1 to increase IL-6, a key player in creating the pagetic microenvironment. Current studies seek to determine the mechanism by which MVNP regulates the competitive balance between TBK1 activity and levels of OPTN (a negative regulator) in osteoclasts. We are also using transgenic mouse models to determine whether increased TBK1 expression in OCL precursors will phenocopy MVNP or cooperate with p62P394L to generate the pagetic phenotype in mice. Further, we are testing whether TBK1 is required for the formation of pagetic lesions in vivo by crossing TBK1 conditional knockout mice with MVNP/P62KI mice. 2) Determing the role and mechanisms of TBK1 and its homolog IKK? in other inflammatory bone diseases, such as multiple myeloma (MM) bone disease. To address this point, we seek to determine the requirement for TBK1 and/or IKK? activity in myeloma cells, osteoclasts, and osteoblast precursor interactions in the MM bone microenvironment. Further, we are working to determine if targeting TBK1/IKK? signaling in vivo will decrease MMBD in an immunocompetent MM mouse model.
