Axon regeneration in the adult CNS is prevented by inhibitors in myelin. These inhibitors seem to modulate RhoA activity by binding to a receptor complex comprising a ligand-binding subunit (the Nogo-66 receptor NgR1) and a signal transducing subunit (the neurotrophin receptor p75). However, in reconstituted non-neuronal systems, NgR1 and p75 together are(More)
BACKGROUND Tumor necrosis factor-like weak inducer of apoptosis (TWEAK), a member of the tumor necrosis factor superfamily, is a multifunctional cytokine known to regulate cellular functions in contexts of injury and disease through its receptor, fibroblast growth factor-inducible molecule 14 (Fn14). Although many of the processes and downstream signals(More)
Two immunohistochemical techniques to determine the presence of yellow fever and dengue antigens in fixed tissue samples were developed for the purpose of making retrospective diagnoses of these viral diseases in humans. A horseradish peroxidase label was used for one technique and an alkaline phosphatase label for the other. In the former technique, acid(More)
Peptidoglycan recognition proteins (PGRPs or PGLYRPs) are pattern recognition molecules that are found in insects and mammals and are critical for innate immune responses. PGRPs bind peptidoglycan, a ubiquitous component of bacterial cell walls, and are involved in killing bacteria, degrading peptidoglycan, and initiating host defense reactions. Relatively(More)
A novel immunoglobulin superfamily (Igsf) protein gene was discovered by computational analysis of human draft genomic DNA, and multiple cDNA clones were obtained. The protein encoded by this gene contains five Ig domains, one transmembrane domain, and an intracellular domain. It has significant similarity with several known Igsf proteins, including(More)
The tight skin 1 (B6.CgFbn1(Tsk)+/+Pldn(pa)/J, henceforth referred to as Tsk1/+) mouse was first described as a spontaneously occurring mutant that resulted in hyperplasia of the subcutaneous loose connective tissue, and has subsequently been proposed to be a model of the human fibrotic disorder scleroderma. We have investigated the Tsk1/+ mouse as a model(More)
The lymphotoxin-beta receptor (LT beta R) is a tumor necrosis factor receptor family member critical for the development and maintenance of various lymphoid microenvironments. Herein, we show that agonistic anti-LT beta R monoclonal antibody (mAb) CBE11 inhibited tumor growth in xenograft models and potentiated tumor responses to chemotherapeutic agents. In(More)
BACKGROUND & AIMS The hedgehog (hh) signaling pathway has been shown to play crucial roles in the development of embryonic gut. However, its role in intestinal development and function beyond the embryonic stage is still undefined. METHODS Expression of hh and its receptor, Patched, were examined by Western blot and X-gal staining. An anti-hh monoclonal(More)
TNF-like weak inducer of apoptosis (TWEAK) is a TNF family member with pleiotropic effects on a variety of cell types, one of which is the induction of proinflammatory cytokines by synovial fibroblasts derived from rheumatoid arthritis (RA) patients. In this study, we report that the serum TWEAK level was dramatically elevated during mouse collagen-induced(More)
Fibrosis is the accumulation of extracellular matrix proteins and is a common end pathway in many chronic diseases. To identify novel mediators of fibrosis we used transcript profiling in a mouse model of kidney fibrosis, the COL4A3 knockout (alport) mouse. One gene that we found up-regulated in fibrotic kidney was GLIPR-2, also known as GAPR-1 and C9orf19,(More)
