Tissue Immunity

We analyse tissue immunity from disease sites to view the responses providing frontline defence and/or driving damage. Our aim is to develop biomarkers and immunotherapies targeted to disease sites.

British Society for Immunology member Dr Laura Pallett shares her experience as an IUIS Rising Star at the inaugural programme in IUIS 2023.

New immunotherapy 'highly effective' against hep B virus

乱伦秀 scientists聽have identified a new immunotherapy to combat the hepatitis B virus (HBV), the most common cause of liver cancer in the world.

Our work

At the IIT, we are fortunate to receive surplus samples from various organs from the surgeons working at the adjacent Royal Free Hospital. This allows us to study immune responses directly isolated from the site of disease, rather than just the fraction that is circulating in the blood.

Many immune cells are compartmentalised within tissues, with specialised adaptations to these sites, and these cannot be sampled from blood. Analysing tissue immunity therefore provides vital insights into the responses providing frontline defence and/or driving damage.聽

Our work aims to use this research to develop biomarkers and immunotherapies targeted to the disease site.

Projects

Liver-resident T cells: adaptation & function

We are investigating how the landscape of the liver influences the phenotypic, metabolic and functional profile of liver-infiltrating and liver-resident T cells using primary human tissue samples. We are also examining cellular interactions occurring within the liver that further shape the effector function of T cells in the context of chronic liver diseases.

Cellular-cross talk in liver fibrosis

We are examining the interplay between liver-resident T cells and the stromal cell niche in the human liver. We are specifically interested in understanding how liver-resident T cells interact and communicate with hepatic stellate cells to cross-regulate cell distribution, survival, function and fibrogenic potential to exacerbate (or limit) the development of liver fibrosis.

Interplay between T cells, myeloid cells and microbial products in liver disease

We have defined a novel mechanism of myeloid instruction of tissue T cells and are studying how this calibrates liver-resident T cell homeostatic, TCR and LPS-dependent effector function in different disease settings and could be harnessed in immunotherapy.

Adapting to life in the liver: An immune cell perspective

We are continually influenced by our location, environment, the people we meet, and even how hungry we are at any moment. Immune cells are no different. For World Liver Day,聽Dr Laura Pallett聽discusses how the identity and function of immune cells is influenced by such factors.
