About

Vaccines and immunotherapies against viral infections and cancer depend upon effective T cell responses, the promotion of antibody-producing B cells, and the establishment of immunological memory.

The VISION of the Groom lab is to understand lymphoid positioning and cellular interactions as key leverage points that direct the outcomes of immune responses. Our aim is to continuously apply these fundamental insights to drive the generation of new therapies for the prevention and treatment of immunological and infectious disease and cancer. In achieving these impacts, the Groom lab will continue to build rich collaborative networks and mentor the next generation of curious, creative immunologists to take on new challenges to improve human health.

Our lab uses a multi-disciplinary approach to dissect the cellular interactions that underpin immune protection and disease. Our major interests are:

  • identifying factors that promote cell migration, and determining how this influences responses to acute and chronic infections, cancer and successful vaccination.
  • determining the spatial niches where cell differentiation decisions occur and long-term memory resides.
  • transcriptionally dissecting the cellular conversations that mediate flexible immune responses and understanding how these are altered during vaccination and infection, in immunodeficiency, asthma, autoimmunity and during immune-related adverse immunotherapy events.
  • determining how to promote immune cell interactions, for example within the tumour microenvironment.
    identifying pathways to target these processes to strategise vaccine design for long-lived protection, and for the development of treatments for inflammatory diseases and cancer.

Systems we use include:

  • advanced imaging methods including whole 3D organ imaging and time-lapse imaging of cell location and migration decisions.
  • diverse vaccination platforms (mRNA-LNP, DC-targeting, Ferritin nanoparticles), infection models (viral, bacterial, helminth and fungal) and cancer models (breast, colon, melanoma) and healthy and patient tissue samples to study flexible immune responses in health and disease.
  • development and analysis of reporter and conditional knockout models to identify how new factors regulate immune protection and memory responses.
  • gene expression profiling of cells based on cellular interactions and spatial distribution.
