198 results about "Galectin" patented technology

Galectins are a class of proteins that bind specifically to β-galactoside sugars, such as N-acetyllactosamine (Galβ1-3GlcNAc or Galβ1-4GlcNAc), which can be bound to proteins by either N-linked or O-linked glycosylation. They are also termed S-type lectins due to their dependency on disulphide bonds for stability and carbohydrate binding. There have been 15 galectins discovered in mammals, encoded by the LGALS genes, which are numbered in a consecutive manner. Only galectin-1, -2, -3, -4, -7, -8, -9, -10 and -12 have been identified in humans. Galectin-5 and -6 are found in rodents, whereas galectin-11, -14 and -15 are uniquely found in sheep and goats. Members of the galectin family have also been discovered in other mammals, birds, amphibians, fish, nematodes, sponges, and some fungi. Unlike the majority of lectins they are not membrane bound, but soluble proteins with both intra- and extracellular functions. They have distinct but overlapping distributions but found primarily in the cytosol, nucleus, extracellular matrix or in circulation. Although many galectins must be secreted, they do not have a typical signal peptide required for classical secretion. The mechanism and reason for this non-classical secretion pathway is unknown.

Drugs containing galectin 9

Galectin 9 exerts various functions depending on its localizations. On the other hand, galectin 9 is expected as participating in various biological functions. Thus, it has been required to clarify the detailed biological activities of galectin 9 and develop galectin 9-related techniques including development of drugs. Human galectin 9 shows a cytotoxic activity and an apoptosis-inducing activity on tumor cells but shows neither cytotoxic activity nor apoptosis-inducing activity on normal cells. Therefore, it is possible to employ galectin 9 proteins, galectin 9 agonists, galectin 9 antagonists, anti-galectin 9 binding protein antibodies, anti-galectin 9 binding sugar chain antibodies, galectin 9-producing, releasing or inducing substances, etc. as antitumor, antiallergic, immunosuppressive agents, drugs for autoimmune diseases, anti-inflammatory agents and active ingredients for adrenocortical steroid hormone alternatives.
