Mucopolysaccharidosis type IIIB is a devastating neurological disease caused by lack of the lysosomal enzyme, α-N-acetylglucosaminidase (NAGLU), leading to toxic accumulation heparan sulfate. Herein we explored pharmacological chaperone approach enhance residual activity NAGLU in patient fibroblasts. Capitalizing on three-dimensional structures two modest homoiminosugar-based inhibitors complex...
Tumor necrosis factor-α (TNF-α) is a pleiotropic cytokine that orchestrates an array of local and systemic effects. For instance, acute exposure to a high dose of TNF-α results in septic shock and fever. We have used interleukin-1β (IL-1β)- and interleukin-6 (IL-6)-deficient mice, along with their wild-type equivalents, to define a role for TNF-α in fever. Briefly, the mice produced prostagland...
Chemically modified proteins are invaluable tools for studying the molecular details of biological processes, and they also hold great potential as new therapeutic agents. Several methods have been developed for the site-specific modification of proteins, one of the most widely used being expressed protein ligation (EPL) in which a recombinant α-thioester is ligated to an N-terminal Cys-contain...
background: natural killer (nk) cells play an important role in early stages of innate immune responses against viral and tumoral attacks. activation of nk cells by leishmaniasis results in secretion of cytokines such as interferon (ifn)-γ and tumor necrosis factor (tnf)-α, which enhances the phagocytosis and clearance of parasite. lipophosphoglycan 3 (lpg3), the leishmania homologous with grp...
The proinflammatory cytokine TNF-α is known to have a direct action on skeletal muscle in mammals. However, little is known regarding the potential effects of cytokines on nonimmune tissues, particularly in skeletal muscle, in fish. The aim of this study was to investigate the effects of recombinant trout TNF-α (rtTNF-α) on skeletal muscle carbohydrate metabolism in rainbow trout (Oncorhynchus ...
PURPOSE Recombinant tumor necrosis factor-alpha (TNF-α) has been utilized as an antineoplastic agent for the treatment of patients with melanoma and sarcoma. It targets tumor cell antigens by impressing tumor-associated vessels. Protein purification with affinity chromatography has been widely used in the downstream processing of pharmaceutical-grade proteins. METHODS In this study, we examin...
Recombinant interferon-alpha (IFN-α) is an approved therapy for chronic hepatitis B (CHB), but the molecular basis of treatment response remains to be determined. The woodchuck model of chronic hepatitis B virus (HBV) infection displays many characteristics of human disease and has been extensively used to evaluate antiviral therapeutics. In this study, woodchucks with chronic woodchuck hepatit...
BACKGROUND As a key link between innate and adaptive immune responses, the interferon (IFN) system is the first line of defense against viral infection. IFN, and in particular, IFN-α, has been used clinically as an effective therapeutic agent for viral infections. However, different subtypes of IFN-α demonstrate distinct antiviral activity. Therefore, it is important to identify IFN-α subtypes ...
The Mycobacterium tuberculosis dihydrodipicolinate synthase (Mtb-dapA) is an essential gene. Mtb-DapA catalyzes the aldol condensation between pyruvate and L-aspartate-beta-semialdehyde (ASA) to yield dihydrodipicolinate. In this work we tested the inhibitory effects of structural analogues of pyruvate on recombinant Mtb-DapA (Mtb-rDapA) using a coupled assay with recombinant dihydrodipicolinat...
