    ABSTRACT: The sequencing of the complete genome for many organisms, including man, has opened the door to the systematic understanding of how complex structures such as the brain integrate and function, not only in health but also in disease. This blueprint, however, means that the piecemeal analysis regimes of the past are being rapidly superseded by new methods that analyse not just tens of genes or proteins at any one time, but thousands, if not the entire repertoire of a cell population or tissue under investigation. Using the most appropriate method of analysis to maximise the available data therefore becomes vital if a complete picture is to be obtained of how a system or individual cell is affected by a treatment or disease. This review examines what methods are currently available for the large scale analysis of gene and protein expression, and what are their limitations.

    ABSTRACT: Several lines of evidence indicate that there may be an inflammatory component to the pathology of Alzheimer's disease (AD), the major form of degenerative dementia in the elderly. Activity of inflammatory cells, and the elaboration of toxic molecules by such cells may be a significant factor in disease progression. In peripheral inflammatory states, the increased activity of matrix metalloproteinase (MMP) enzymes are a major cause of tissue breakdown and secondary damage in diseases such as rheumatoid arthritis. The activity of such enzymes in the normal or diseased central nervous system is, however, not well characterized. We have therefore determined the levels of MMP 1 (collagenase) in the normal human brain and in AD. MMP1 levels were relatively low though were significantly elevated by approximately 50% in AD in all cortical areas examined. Given the activity towards collagen of MMP1, it is possible that enhanced MMP1 activity in AD, may contribute to the blood-brain barrier dysfunction seen in AD.
