The edible mushroom Lentinula edodes (shiitake) contains many bioactive compounds. In the present study, we cultivated L. edodes mycelia in solid medium and examined the hot-water extract (L.E.M.) for its suppressive effect on concanavalin A (ConA)-induced liver injury in mice. ConA injection into the tail vein caused a great increase in the serum aspartate aminotransferase (AST) and alanine am...

Taenia saginata metacestode antigens have been constituted a useful alternative antigen for neurocysticercosis (NC) serodiagnosis, particularly due to an increasing difficulty to obtain Taenia solium homologous antigen. Cross-reactivity with Echinococcus granulosus infection occurs in homologous and heterologous antigens and could be avoided by using different purified methods. The present stud...

Challenge of neutrophils with concanavalin A (ConA), formyl-methionyl-leucyl-phenylalanine (FMLP), and phorbol 12-myristate 13-acetate (PMA) induced the tyrosine phosphorylation of several proteins. Among these proteins we have identified two mitogen-activated protein kinase (MAPK) isoforms of 43 kDa (p43 MAPK) and 45 kDa (p45 MAPK) molecular mass. Moreover here we show that: (1) FMLP induced t...

The prevalence of autoimmune hepatitis (AIH) is increasing, yet specific pharmacotherapies remain to be explored. present study aimed investigate the effects sophoricoside (SOP), a bioactive component medical herbs, on AIH and elucidate underlying mechanisms. Bioinformatic approaches were used predict potential targets regulatory mechanisms SOP AIH. evaluated by determining expression levels in...

Mesenchymal stromal cells (MSC) mobilization and recruitment by experimental vascularizing tumors involves membrane type 1-matrix metalloproteinase (MT1-MMP) functions. Given that the mannose-specific lectin Concanavalin-A (ConA) induces MT1-MMP expression and mimics biological lectins/carbohydrate interactions, we synthesized and tested the potential of 11 mannoside clusters to block ConA acti...

Gut microbiota are implicated in many liver diseases. Concanavalin A (ConA)-induced hepatitis is a well-characterized murine model of fulminant immunological hepatic injury. Oral administration of pathogenic bacteria or gentamycin to the mice before ConA injection, liver injury and lymphocyte distribution in liver and intestine were assessed. Our data show that administration of pathogenic bact...

The skin-swelling test is a simple and widespread method used in field ecological research to estimate cellular immune responsiveness in animals. This immunoecological test is based on measuring the magnitude of tissue swelling response at specific times following subcutaneous application of an experimental pro-inflammatory stimulant. In the vast majority of studies across vertebrate taxa, phyt...

OBJECTIVE This study investigated the immunoregulatory and protective roles of Yinchenhao decoction, a compound of Chinese herbal medicine, in a mouse model of concanavalin A (ConA)-induced chronic liver injury. METHODS Female BalB/c mice were randomly divided into 4 groups: normal control, ConA model, ConA model treated with Yinchenhao decoction (400 mg/kg, orally), and ConA model treated wi...

Blomia tropicalis, Dermatophagoides pteronyssinus and D. farinae are prevalent house dust mites. Concanavalin A-binding components derived from B. tropicalis (Bt-ConA extract) are highly immunogenic in allergic diseases. The aim of the present study was to evaluate the humoral and cellular immune responses to B. tropicalis in mite-sensitized patients. A total of 137 patients with allergic rhini...
