This is the first study to our knowledge to report a novel mutation in the interferon regulatory factor 8 gene (IRF8G388S) associated with multiple idiopathic tooth root resorption, a form of periodontal disease. The IRF8G388S variant in the highly conserved C‐terminal motif is predicted to alter the protein structure, likely impairing IRF8 function. Functional assays demonstrated that the IRF8G388S...
Recent epidemiological studies have identified interferon regulatory factor 8 (IRF8) as a susceptibility factor for multiple sclerosis (MS). However, how IRF8 influences the neuroinflammatory disease has remained unknown. By studying the role of IRF8 in experimental autoimmune encephalomyelitis (EAE), a mouse model of MS, we found that Irf8−/− mice are resistant to EAE. Furthermore, expression of...
IRF8 is a transcription factor of the IRF family expressed in macrophages and dendritic cells (DCs). It enhances type I interferon induction in pDCs and IL12p40 in CD8+DCs and macrophages. We have observed that IRF8 regulates transcription of a series of genes in the autophagy pathway in macrophages and DCs in response to IFNg and toll-like receptor signaling, and plays a critical role in the formation...
Inherently hierarchic nature of proteins makes multiscale computational methods especially useful in the studies of folding and other functional dynamics. With the multiscale strategies, one can achieve improved accuracy and efficiency by coupling the atomistic and the coarse grained simulations. Depending on the problems studied, very different implementation protocols can be used to realize the...
Recently it has been reported that a cathepsin B inhibitor, CA-074Me, attenuates ecotropic murine leukemia virus (Eco-MLV) infection in NIH3T3 cells, suggesting that cathepsin B is required for the Eco-MLV infection. However, cathepsin B activity was negative or extremely low in NIH3T3 cells. How did CA-074Me attenuate the Eco-MLV infection? The CA-074Me treatment of NIH3T3 cells inhibited cathepsin...
Human immunodeficiency virus type 1 (HIV-1) infection is initiated by successive interactions of viral envelope glycoprotein gp120 with two cellular surface proteins, CD4 and chemokine receptor. The two most common chemokine receptors that allow HIV-1 entry are the CCR5 and CXCR4. The CD4 and CCR5 are mainly localized to the particular plasma membrane microdomains, termed raft, which is rich in glycolipids...
Ezrin, radixin, and moesin (ERM) proteins supply functional linkage between integral membrane proteins and cytoskeleton in mammalian cells to regulate membrane protein dynamisms and cytoskeleton rearrangement. To assess potential role of the ERM proteins in HIV-1 lifecycle, we examined if suppression of ERM function in human cells expressing HIV-1 infection receptors influences HIV-1 envelope (Env)-mediated...
Ecotropic murine leukemia viruses (MLVs) recognize the third extracellular loop of the receptor, cationic amino acid transporter type 1 (CAT1). The CAT1 protein contains two conserved N-linked glycosylation sites in the third extracellular loops of the mouse, rat, and hamster receptors (mCAT1, rCAT1, and hCAT1, respectively). Glycosylation of the rCAT1 and hCAT1 receptors inhibits ecotropic MLV infection...
