Science medicine, and the future .3. Role of molecular cell biology in understanding disease

Abstract

Molecular techniques have revolutionised our knowledge of cell and tissue function in both health and disease. We already have new and powerful treatments based on an understanding of communication between cells by messenger molecules called cytokines. Furthermore, there is great therapeutic promise in defining molecules which regulate cell adhesion, motility, proliferation, survival, and death. Rational manipulation of cell and tissue function for therapeutic ends may be much closer than you think.
