c-Met Agonists: Use for the Treatment of Tissue Damages
Referenznummer TO 02-00263
The Challenge
Approximately eight million surgical procedures are performed annually only in the U.S. to treat tissue damage resulting from accidents, birth defects, hereditary disorders, and other diseases. As traditional tissue repair procedures are inefficient, potentially painful to the patient, and costly to perform, there is a continued demand for alternative efficient approaches to treat the damage of internal organs or skin.
Technology
The tyrosine kinase Met, the product of the c-met proto-oncogene and the receptor for hepatocyte growth factor/scatter factor (HGF/SF), mediates signals
critical for cell survival and migration. The human pathogen Listeria
monocytogenes exploits Met signaling for invasion of host cells via its surface
protein internalin B (InlB). The present technology discloses an isolated recombinant dimer derived from internalin B that binds to c-Met with very high specificity and activates the c-Met dependent signalling pathway. The dimer acts as an agonist of c-Met signalling and could support the development of a pharmaceutical composition useful for wound healing or tissue regeneration after tissue damage, in particular, skin or mucosal tissue damages but
also damages or injuries of liver, lung or heart muscle, which may occur e.g. in the course of progressing diabetes. Additionally, the dimer could be developed as a proliferating agent stimulating or enhancing cell proliferation in particular for tissue engineering techniques.
Commercial Opportunity
The technology is offered for co-development of various tissue regeneration approaches or in-licensing.
Developmental Status
The status of the development is still research. The scattering potency and the induction of cell proliferation could be shown in different cell culture assay formats.
Patent Situation
European application filed in June 2008 (EP08011562.9), international application (PCT) filed June 2009.
