Timetable

Tuesday 10 May

09:45 – 10:00 Welcome

10:00 – 10:40 Grant Lythe, University of Leeds, “Stochastic modelling”
Abstract: We model the cells and molecules of the immune system and its bacterial and viral foes by defining simple rules at the level of individual cells. In principle, stochastic models are better than ODEs because they respect the facts that different outcomes are possible with a single initial condition, and that the number of cells is an integer. ODEs may describe the mean behaviour, but do not yield the probability of, or time to, extinction.

10:40 – 11:20 Tom Mann, Salk Institute for Biological Sciences, “Lessons learned from counting antigen-specific T cells responding to infection”

Wednesday 11 May

09:45 – 10:00 Welcome

10:00 – 10:40 Jessica Gaevert, St Jude Children’s Research Hospital, “How Do Cross-Reactive T Cells Work?”
Abstract: Cross-reactive TCRs may play a key role in allowing the immune system to adapt to rapidly evolving pathogens, such as influenza A virus (IAV). This project focuses on how cross-reactive TCRS shape the repertoire during repeated IAV challenges, and how previous infections inform future responses via selected cross-reactive T cell pools.

ESR 7 Carina Bruckmaier, UMC Utrecht, “Tissue resident memory T cells in human tissue and the question about their lifespan”

Symposium on "Quantitative methods and modelling in T cell immunology", 12 May

On 12 May there will be a Symposium on “Quantitative methods and modelling in T cell immunology”. This will consist of research talks for a wider audience and external participants are welcome to attend. Download the poster

The symposium will be held from 09:00 CEST at Salle Dussane, 45 rue d’Ulm, ENS, 75005 Paris.

Timetable

09:00 – 09:15 Welcome

09:15 – 09:55 Philippe Bousso, Institut Pasteur
“Decoding the mode of action of tumour immunotherapies using intravital imaging”
Abstract: Understanding complex interactions between the immune system and the tumor microenvironment is an essential step towards the rational development and optimization of immunotherapies. Several experimental approaches are available to tackle this complexity but most are not designed to address the dynamic features of immune reactions, including cell migration, cellular interactions, and transient signaling events. By providing a unique means to access these precious parameters, intravital imaging offers a fresh look at intratumoral immune responses at the single-cell level. We will illustrate how in vivo imaging sheds light on fundamental aspects of tumor immunity and helps elucidate modes of action of immunotherapies such as CAR T cell therapy.

09:55 – 10:35 Aleksandra Walczak, Ecole Normale Supérieure
“How personalised is your immune system?”

10:35 – 11:00 Break

11:00 – 11:40 Leïla Perié, Institut Curie
“A quantitative gaze at blood cell production”
Abstract: Hematopoiesis is the process by which hematopoietic stem and progenitor cells give rise to all blood cells. Hematopoietic cells can be divided into at least 13 cell types, corresponding to approximately tens of trillions of cells distributed among most tissues of the body.
As most hematopoietic cells are short-lived, hematopoiesis is a constantly regenerating process. Moreover, hematopoiesis flux can vary in response to changing demands for blood cells in peripheral tissues, for example during bleeding or infection. Hematopoiesis starts from a few hematopoietic stem and progenitor cells (HSPC) to finally produce many mature cells. Understanding the mechanisms that allow the small pool of HSPCs to meet changing requirements for such large blood cell numbers remains a challenge. In this talk, I will present some general quantitative consideration of hematopoiesis and recent results on quantifying cell dynamics in hematopoiesis.

11:40 – 12:20 Ken Duffy, Maynooth University
“Inferring division counts in vivo, and what they tell us about T cell memory”

12:20 – 14:00 Lunch

14:00 – 14:40 Grégoire Altan-Bonnet, NIH
“Robotic mapping and machine learning of cancer immunotherapy”

14:40 – 15:20 Tom Mann, Salk Institute for Biological Sciences

15:20 – 16:00 Break

16:00 – 16:40 Thomas Finnie, Public Health England
“In-host modelling of SARS-CoV-2 with information relevant to disease control”
Abstract: In this talk I will show how modelling of the disease process within human tissues, using human challenge trial data, may inform a wider picture of disease control and how that can be used in assisting policy development.
