Goal: Advance our understanding of how host physiology and disease pathophysiology are affected by the gut microbiota; define research needs and opportunities for interrogating host-microbiota interactions and their role in modulating disease processes within NIDDK’s mission.

Format: Retreat-style format designed to (1) highlight the clinical perspective of how diseases are affected by the gut microbiota; (2) provide case studies for studying host-microbiota interactions in the context of inflammation and epithelial barrier function, nutrient metabolism and energy balance, and communication with distant organs; and (3) introduce novel frameworks for understanding the factors that regulate host-microbiota interactions and stasis. Sessions will have facilitated panel discussions to address the major scientific questions that will advance our understanding of host-microbiota interactions and how physiology and disease pathophysiology are affected by the gut microbiota.

Output: Planning group will develop a workshop summary to highlight the research needs and opportunities identified by workshop participants.

Abstract/Poster Information: The abstract submission deadline is August 22nd, 2014. The poster board dimensions are 4' (H) x 6' (W).

Meeting Location:
Natcher Conference Center
Building 45, Conference Room E1E2
National Institutes of Health
Bethesda, MD

NIH Visitor Information:
The Natcher Conference Center is located on the NIH Campus in building 45. For a map, general information, and directions to and around the NIH Campus, visit: http://parking.nih.gov/visitor_access_map.htm.

NIH Security:
The NIH, like all federal government facilities, has instituted security measures to ensure the safety of NIH employees, patients, and visitors. The national threat advisory level, determined by the Department of Homeland Security (http://www.whitehouse.gov/homeland), currently is yellow (elevated).

Perimeter Security: All visitor vehicles, including taxicabs, hotel and airport shuttles, delivery trucks, and vans will be inspected before being allowed on campus. Visitors will be asked to show one (1) form of identification (a government-issued photo ID: driver’s license, passport, green card, etc.) and to state the purpose of their visit. Be sure to allow at least 15-20 minutes for this vehicle inspection procedure.

Building Security:
Due to the checking of IDs at the perimeter, employees and visitors will not be required to show their ID again to gain access to the majority of buildings on the NIH Campus during the normal business day.
Employees and visitors should continue to wear their identification prominently at all times while on campus.
Guards will remain at certain buildings to address specific program requirements, such as sensitive research and safety concerns. At building entrances where guards are posted:

  • Employees must show a DHHS-issued photo ID (for example, your NIH-issued ID badge).
  • Visitors may be required to log-in, wear a visitor’s pass, and be escorted by an employee through the building.
  • Visitors may be required to pass through a metal detector and have bags, backpacks, or purses inspected or x-rayed as they enter buildings.
  • Security staff will confiscate any suspicious or potentially dangerous materials. U.S. code prohibits bringing any dangerous weapons onto federal property, including anything with a blade longer than 2½ inches. Meeting participants may want to leave extra bags or personal materials at their hotel to minimize the time needed for inspection.

Weekday Pedestrian Campus Access:
All visitors must enter through the NIH Gateway Center at Metro or the West Gateway Center (see the Visitor Map at http://parking.nih.gov/visitor_access_map.htm).

  • Gateway Center
    Wisconsin Avenue at Gateway Drive (near the Metro)
    Open 24 hours, 7 days per week

  • West Gateway Center
