An individual-based model to explore the impact of psychological stress on immune infiltration into tumour spheroids

no code implementations24 Jul 2023 Emma Leschiera, Gheed Al-Hity, Melanie S. Flint, Chandrasekhar Venkataraman, Tommaso Lorenzi, Luis Almeida, Chloe Audebert

In recent in vitro experiments on co-culture between breast tumour spheroids and activated immune cells, it was observed that the introduction of the stress hormone cortisol resulted in a decreased immune cell infiltration into the spheroids.

A mathematical model to study the impact of intra-tumour heterogeneity on anti-tumour CD8+ T cell immune response

no code implementations12 Jul 2021 Emma Leschiera, Tommaso Lorenzi, Shensi Shen, Luis Almeida, Chloe Audebert

First, the results of numerical simulations of this model indicate that the presence of a larger number of sub-populations of tumour cells that express different antigens is associated with a reduced ability of CD8+ T cells to mount an effective anti-tumour immune response.
