Clinical proteomics is engaged in research on the interface of chemistry , biochemistry and medicine , using modern research tools , such as , among others, microextraction and separation of complex biological samples , methods for the identification of proteins by mass spectrometry and bioinformatics . In modern proteomics includes both basic research as well as clinical research . Between these disciplines there is a continuous exchange of information ( translation) , contributing to the continued progress of knowledge about specific diseases .

Since the early nineties , research is the interactions between the nervous system and the immune system. Substances that may affect these processes include glucocorticosteroids , opioid peptides , polypeptides , hormones, pituitary and catecholamines . Catecholamines inhibits the activity of T lymphocytes and B and produce anti-tumor immune response . Proving in 1994, the presence and biosynthesis of catecholamines in cells of the immune system has become an important step in the research links between the nervous system and the immune system.
