Injection of Hylan G-F20 (HY) into joints may provoke local flares, which mechanisms may involve reaction to protein contaminants. We have previously developed a protein-free saline-soluble galactomannan derived from guar gum (GM) that displays both analgesia and chondroprotection in We show that galactomannan, a polysaccharide consisting of a mannose backbone with galactose side groups present on the cell wall of several fungi, induces a reprogramming of the inflammatory response in human macrophages through dectin-1 receptor. The nuclear factor kappa-light-chain-enhancer of
A polysaccharide characterized as galactomannan (GMann) with a molecular weight of 117.76 kDa was isolated from the aqueous extract of Caesalpinia gilliesii (C. gilliesii) seeds then assessed for antiproliferative potential against human hepatocellular carcinoma cell line (HepG2). Further, HCC was
Galactomannan (GM), a natural polymer, is recognized to specifically target macrophage mannose receptors (CD206). Interestingly, some reports indicate that GM has an ability to induce pro-inflammatory (M1-like, tumericidal) polarization in macrophages, suggesting its potential use as an anti-cancer
Locust bean gum (LBG) galactomannan has been claimed to have applications in the biopharmaceutical field. However, the effects of LBG galactomannan on immunomodulatory aspects are not yet clear. The purpose of this study was to over-express thermostable β-d-mannanase from the thermophilic
Galactomannan (GAL), a polysaccharide present on the cell wall of several fungi, has shown an ability to modulate inflammatory responses through the dectin-1 receptor in human macrophages. However, studies evaluating the modulatory properties of this polysaccharide in in vivo Galactofuranose (Galf) is the five-membered ring form of galactose exclusively found in nonmammalian species, among which several are pathogens. To determine the putative role of this carbohydrate in host-pathogen interactions, we synthesized multivalent gold nanoparticles carrying Galf (Galf-GNPs)
The study is oriented at the in vitro evaluation of the immunobiological activity and efficacy of synthetically prepared isomeric pentasaccharides representing fragments of Aspergillus fumigatus cell-wall galactomannan and containing β-(1→5)-linked tetragalactofuranoside chain attached to O-6 (GM-1)
OBJECTIVE
To assess the value of Aspergillus galactomannan (GM) double-direct sandwich enzyme-linked immunosorbent assay (ELISA) in the diagnosis of invasive pulmonary aspergillosis (IPA).
METHODS
Ninety adult SD rats were randomly divided into 5 groups, including 4 groups of pulmonary infection by
Salmonella enterica serovar Typhimurium is a facultative intracellular pathogen that causes inflammation, necrosis, and diarrhea in pigs, as well as being an important source of food-borne diseases in humans. Probiotics and prebiotics are promising alternatives to antibiotics to control and prevent
We describe an autologous stem cell transplant recipient who developed immune reconstitution inflammatory syndrome (IRIS) associated with Aspergillus terreus invasive pulmonary infection after recovery from neutropenia. Clinical and radiological worsening of pulmonary invasive aspergillosis
OBJECTIVE
Clinical and radiologic deterioration is sometimes observed during neutrophil recovery in patients with invasive pulmonary aspergillosis (IPA). This deterioration can be caused by immune reconstitution inflammatory syndrome (IRIS) as well as by progression of the IPA. However, there is
Plant polysaccharides present an interesting potential as immunomodulators, particularly in the induction of antitumoral responses, principally because of their molecular complexity and low in vivo toxicity. Activation of dendritic cells (DCs) could improve antitumoral responses usually diminished
Galactomannan and (1→3)-β-D-glucan are useful biomarkers of invasive pulmonary aspergillosis (IPA). However, the effects of immunosuppression on levels of galactomannan or (1→3)-β-D-glucan in IPA are not well understood or quantified. We therefore studied the simultaneous levels of galactomannan and
We describe a novel wound dressing (HR006) with two components: a lyophilized matrix of the galactomannan from locust bean gum (LBG) and an antioxidant hydration solution (AHsol) containing curcumin and N-acetyl-L-cysteine (NAC). Physico-structural analyses of the LBG matrix revealed homogeneous
