Gut and respiratory infections are among the leading causes of illness and death worldwide. Yet it is still unclear why some people get sicker than others and what drives infection at the level of cells and molecules.

Grants

What they work on

  1. Determine how human rotavirus and norovirus replication and immune responses in human intestinal organoids change with co-culture of the donor's own immune and nerve cells, co-infection with other pathogens, and commensal bacteria.
  2. Characterize immune responses to respiratory syncytial virus (RSV) and coronavirus in human nose and lung organoids co-cultured with the donor's own immune cells, to build preclinical models that mimic human disease.
  3. Investigate the lung-gut axis of respiratory virus disease by infecting human intestinal organoids with respiratory viruses and examining the underlying mechanisms.
  4. Identify molecular drivers of susceptibility to enteroaggregative E. coli using immune co-culture, flow and stiffness cues, and an integrated organoid system with all four intestinal segments.
  5. Use organoid lines from many human donors to examine how host genetics shapes responses to gut and respiratory infections.

More about the research

One reason is that cell lines and animals often fail to mimic human disease well. This multi-institution center at Baylor College of Medicine, Rice University and MD Anderson Cancer Center takes a different approach. It uses human organoids, small 3D tissues grown from human stem cells that resemble real organs, to study infections of mucosal surfaces, the moist linings of the gut and airways. The center renews an earlier program that produced 42 publications.

Why it matters

Diarrheal and respiratory infections such as rotavirus, norovirus, RSV, coronavirus and pathogenic E. coli sicken and kill large numbers of people worldwide. Human organoid models that better reproduce human tissue could reveal why some people are more susceptible than others. They could also serve as preclinical platforms for testing whether new treatments for these infections are safe and effective.
