14) Host Response
Abstract
How do we know if an individual has been exposed? What symptoms will develop? How soon? How can the effects of various attack agents be differentiated? How much time do we have to initiate medical intervention? Host Response provides the tools and data to understand what the body’s response will be after exposure to Chemical-Biological (CB) threat agents under a variety of realistic concentrations and routes of entering the body (e.g., lungs, skin, mouth, etc.) and looking at sudden versus long-term/low exposure. Data from host response studies are also used to develop exposure limits acceptable for continued utilization of decontaminated equipment in a combat environment to inform mission planning, requirements generation, capability development and model development for the larger Chemical and Biological Defense Program (CBDP) Enterprise, Intelligence and other government stakeholders. Host Response also includes developing the ability to rapidly predict the human response to chemical and biological threat agents, especially new/emerging threats. While these capabilities also work to close knowledge gaps associated with “traditional” threats, they are key to having an ability to explore effects associated with exposure to mixed threat agents, assesses bioavailability of threat agents that have been ‘coated’ to increase viability and/or decrease the detectability of a threat agent. Understand how the body’s response to such ‘coated’ agents is different versus un-coated threats is a vital part of our Threat Agent Science mission.
