Corneal and Ocular Immunology Unit


Research Overview


Our research is aimed at understanding how corneal epithelial cells, immune cells and sensory nerves interact to achieve homeostasis and rapid recovery following injury, exposure to noxious stimuli and during normal ageing. Our laboratory is based in the Melbourne Brain Centre, where we have access to a suite of state-of-the-art instruments to enable in vivo clinical imaging of the mouse eye, along with ex vivo imaging of corneas, tissue culture and molecular biology techniques.

Corneal immune cells

The mouse and human cornea contains populations of resident immune cells such as macrophages and dendritic cells. These cells play an important role in generating innate inflammatory responses against microbial pathogens and sterile injurious stimuli, as well as interacting with the dense population of sensory nerves that supply the corneal epithelium.

Neuroimmune interactions

Recent studies suggest that corneal dendritic cells are closely associated with corneal sensory nerves. The nature of this relationship is thought to be spatial (i.e. the two entities are physically in contact), physiological (dendritic cells are thought to promote nerve homeostasis) and immunological (i.e. nerve stimulation affects dendritic cell activation). We have a range of active projects in the lab investigating the interplay of corneal sensory nerves and the effect that tissue injury and exposure to noxious stimuli has on the activation state of the resident immune cells.

Major techniques

  • In vivo clinical imaging of corneal inflammation using spectral domain optical coherence tomography
  • Ex vivo confocal imaging of immunostained tissues, 3D reconstruction and image analysis
  • Analysis of chemokine, cytokine and neuropeptide gene expression and production (qPCR and ELISA
