Developments in systems biology: implications for health and biochemical security

Biological processes occur within complex, vital physiological systems. Systems biology seeks to understand how physiological systems function as a whole, integrating information about interactions in a biological system through computer-assisted modeling, aiming to identify relationships not found within individual biological units. Coupled with advances in the life sciences and computing power, this research is yielding an enormous amount of information about specific targets of vital physiological processes, and enabling predictions about how these targets may respond to a disturbance or change in signaling. This information can be greatly beneficial in treating complex diseases. It also has extended the spectrum of potential threat agents to include bioregulators, which to a great extent regulate the functioning of the nervous, endocrine, and immune systems. There is potential for misuse of the knowledge gained from these studies, and improved methods of targeted delivery of biochemicals make them more feasible weapons agents. Moreover, biochemical security concerns in systems biology are embedded within the larger domain of cyberbiosecurity. There remains a need for proactive approaches to the formulation of biochemical-security-oversight policy that would encompass developments at this interface of the life sciences and information technology.
