Healthy mouse cornea showing the distribution of macrophages throughout the eye.
In the centre of the cornea, macrophages are a few and spaced out while the edges of the cornea (Limbus)听contain many more macrophages. Stained for cell nuclei by DAPI (Blue) and for macrophages by F4/80 (Green)听and CD11b (Magenta). Imaged using a spinning disk confocal, Nikon CSU-X1

Intestinal helminth infection is a neglected tropical disease affecting over 2 billion people worldwide. These macroscopic worms migrate and cause inflammation to host tissue during听their life cycle. However, most infections are well-tolerated due to activation of host pathways that limit tissue damage and stimulate repair. Our preliminary results suggest that microbes play a role in this tissue healing response, as this image depicts persistent inflammation (jellyfish head) above villi of the small intestine (jellyfish legs) in infected mice that lack a gut microbiota. We are exploring the effect of the gut microbiota, a vast community of microorganisms, during this tissue repair process by imaging different types of cells in the small intestine at localized sites of damage. The goal of this research is to inform clinical approaches to enhance protection from infectious diseases.
