Disease relevance of Laminaran


High impact information on Laminaran

  • To generate a vaccine to protect against a variety of human pathogenic fungi, we conjugated laminarin (Lam), a well-characterized but poorly immunogenic beta-glucan preparation from the brown alga Laminaria digitata, with the diphtheria toxoid CRM197, a carrier protein used in some glyco-conjugate bacterial vaccines [6].
  • We show that laminarin, a beta-1,3 glucan with elicitor activity in tobacco (Nicotiana tabacum), becomes, after chemical sulfation, an inducer of the salicylic acid (SA) signaling pathway in tobacco and Arabidopsis thaliana [7].
  • In tobacco cell suspensions, the oxidative burst induced by the laminarin sulfate PS3 was Ca2+ dependent but partially kinase independent, whereas laminarin triggered a strickly kinase-dependent oxidative burst [7].
  • Family 6 CBMs (CBM6s) are distinct from other CBM families in that these protein modules contain multiple distinct ligand binding sites, a feature that makes CBM6s particularly appropriate receptors for the beta-1,3-glucan laminarin, which displays an extended U-shaped conformation [8].
  • Kappa-carrageenases belong to family 16 of the glycoside hydrolases, which essentially encompasses polysaccharidases specialized in the hydrolysis of the neutral polysaccharides such as agarose, laminarin, lichenan, and xyloglucan [9].

Chemical compound and disease context of Laminaran


Biological context of Laminaran

  • The beta-1,3-glucan binding protein could only be affinity-precipitated from crayfish plasma by the beta-1,3-glucans laminarin or curdlan (an insoluble beta-1,3-glucan), while mannan or dextran did not bind to the beta-1,3-glucan binding protein [13].
  • IC50 values for inhibition of binding to low and high affinity sites by the most highly sulphated laminarin sulphate (LAM S5; degree of sulphation 2.31) were 12 +/- 8 micrograms/ml and 69 +/- 66 micrograms/ml, respectively [14].
  • However, when they were used together (0.4 mg/ml alpha-mannan and 0.4 mg/ml laminarin), almost complete inhibition of phagocytosis was obtained [15].
  • These effects of laminarin sulfate may have potential clinical applications in diverse situations such as wound healing, angiogenesis, and atherosclerosis [16].
  • Laminarin did not induce cell death [17].

Anatomical context of Laminaran

  • Furthermore, the soluble carbohydrate beta-glucan receptor antagonists laminariheptaose and laminarin also substantially reduce the ability of the P. carinii cell wall isolate to stimulate macrophage-inflammatory activation [18].
  • In contrast, a number of beta-glucans were active against zymosan but not EsIgG ingestion with a 75% reduction in the number of monocytes ingesting zymosan occurring with 100 micrograms/ml laminarin, 500 micrograms/ml soluble pachyman, and 900 micrograms/ml of soluble pustulan [19].
  • To evaluate the involvement of LGBP in the prophenoloxidase (proPO) activating system, a polyclonal antibody against LGBP was made and used for the inhibition of phenoloxidase (PO) activity triggered by the beta-1,3-glucan laminarin in the hemocyte lysate of crayfish [20].
  • Characterisation of a laminarin sulphate which inhibits basic fibroblast growth factor binding and endothelial cell proliferation [14].
  • Tritiated glycans (amylose, dextran, laminaran, the insoluble beta-1,3-D-glucan, and agarose) and the p-nitrophenyl-glycopyranoside derivatives were used as substrates to investigate whether the macrophages contained or released glucanases capable of degrading alpha-1,4-D-glucans, alpha-1-6-D-glucans, beta-1,3-D-glucans, and agarose respectively [21].

Associations of Laminaran with other chemical compounds


Gene context of Laminaran


Analytical, diagnostic and therapeutic context of Laminaran

  • The final product contained only IgG by SDS-PAGE and was shown to be specific by its selectively blocking binding of 125I-mAb OEA10 to laminarin [31].
  • Immunospecific rabbit antibodies were produced by immunization with bovine serum albumin-conjugated laminarin [beta (1-->3)-glucan] and affinity chromatography on epoxy-Sepharose-coupled beta (1-->3)-glucans [32].
  • We examined the pharmacokinetics of three water-soluble glucans (glucan phosphate, laminarin, and scleroglucan) after oral administration of 1 mg/kg doses in rats [33].
  • Selected water-soluble, native polysaccharides--such as amylose, laminaran, pullulan--and derivatized polysaccharides--methyl cellulose, hydroxypropyl cellulose, and carboxymethyl amylose sodium salt (CM-Am)--were investigated as chiral selectors in capillary electrophoresis [34].
  • In contrast, laminarin does not interfere with opsonization whereas mannan blocks the process, blocking the binding of a 57 kD plasma component as detected by Western immunoblot [35].
