    摘要: The present invention discloses novel antibodies that specifically bind to the human platelet membrane protein Glycoprotein VI (GPVI) and their monovalent fragments or derivatives. The antibodies of the invention are antibodies from hybridoma clone 390 and antibodies that bind to an epitope which is similar to the conformational epitope recognized by antibody from hybridoma clone 390. These antibodies and Fab fragments are able to block collagen binding and thus preventing platelet activation by collagen. The invention also relates to hybridoma clones and expression plasmids for the production of disclosed antibodies and Fab fragments. The present invention further refers to the uses of monovalent antibody fragments to manufacture research, diagnostic and immunotherapeutic agents for the treatment of thrombosis and other vascular diseases.

    摘要: The present invention concerns Plac8, a new target involved in adipogenesis modulation. Using a siRNA approach, the inventors demonstrated that decrease in Plac8 activity in preadipocytes and adipose tissue induces a decrease in adipogenesis. Thus, the present invention relates to modulators of Plac8 activity as well as screening test for identification of modulators of the activity of this target, and their use, especially in pharmaceutical composition, to modulate adipogenesis and thus treat obesity and related disorders.
