DCLK1

DCLK1 is a microtubule-associated protein which catalyses the polymerisation of tubulin dimers. This process is critical in the formation of microtubules, a major component of the cellular cytoskeleton, and also important in many cellular functions such as cell division and migration. DCLK1 expression is excessively upregulated in various types of cancer and, pertinently, high DCLK1 expression is significantly correlated with poorly differentiated cancers, lymph node metastasis, advanced clinical stage, and poorer overall patient survival, suggesting that the overexpression of DCLK1 may accelerate cancer development.

Tuft cells

A structurally unique cell type, best characterised by striking microvilli which form an apical tuft. These cells represent approximately 0.5% of tissue epithelial cells depending on location. Tuft cells act as luminal sensors, linking the luminal microbiome to the host immune system, which may make them a potent clinical target for modulating host response to a variety of acute or chronic immune-driven conditions.

Our lab is using powerful single-cell sequencing approaches and has developed experimentally tractable tools in order to interrogate this rare cell population, with the aim of unravelling its physiological importance in inflammation-driven gastrointestinal diseases, such as colon and gastric cancers.

Innate lymphoid cells

These cells are a newly discovered type of innate immune cell which resemble lymphocytes but lack a T cell receptor. They are predominantly found in mucosal surfaces associated with epithelial tissues, such as the gut, lung and skin, and have important roles in immunity, infection and homeostasis. Our lab is investigating the interplay between Tuft cells and ILC2 cells during gastric homeostasis and cancer.
