Peroxisome proliferator-activated receptor-gamma (PPARg) is one of the most intensively studied nuclear receptors of the last two decades. The receptor owe its popularity to pleiotropic actions on many important physiologic processes of single cells and whole organisms such as energy homeodynamic regulation, control of glucose and lipid metabolism, proliferation, differentiation, apoptosis, inflammation or angiogenesis. Beside natural ligands some synthetic agonists, antagonists and modulators of PPARg are already known.

Focal Adhesion Kinase - FAK ( focal adhesion kinase) belongs to the group of non-receptor protein tyrosine kinases . It occurs in the cytoplasm of most cells , including osteoblasts. At the time of its activation , the interaction of integrin associated protein extracellular matrix call is incorporated into platelet adhesion . FAK kinase in the presence of these structures is closely related to a function that plays in cellular processes such as adhesion, migration, proliferation . FAK -deficient cells show a much slower growth and reduced mobility.

The effector cells of the immune system are able to recognize the infected cells , transformed , and how recently found , cells of various types of stressors . One way is to recognize the identification of the latter, stress-induced cell surface molecules . The best known receptor involved in this type of reaction is the C -type lectin receptor called NKG2D on NK cells present , TGD lymphocytes , CD8 + lymphocytes and macrophages Tab . Described 4 NKG2D ligand family . These are human molecules MIC A and B ( sometimes also referred to as MICA and MICB ) and ULBP and the mouse RAE -1 and H60 .
