Conceptual Biology & Medicine
The goal of our interdisciplinary group is to offer an enriched conceptualization, explanation, and modelling of biological processes, particularly through our ERC-funded IDEM project. We reach this aim through what we call « Philosophy in biology », an innovative way to combine the contributions of philosophy of biology, experimental biology, and medical biology. We are focused first and foremost on immunology, but also work on conceptual issues related to microbiology, evolutionary biology, ecology, developmental biology, physiology, cancer biology, and the medical sciences.
Our group currently works on four main projects:
Within Thomas Pradeu’s ERC Starting Grant project (2015-2020), entitled “IDEM” (for “Immunology, Development, and the Microbiota: Understanding the Continuous Construction of the Organism”), we aim at understanding how the microbiota is involved in the construction and maintenance of the host organism.
IDEM consists of four areas:
In total, 5 to 6 postdocs will be hired in this project. For further information, please visit the ERC IDEM’s webpage.
In collaboration with medical doctors of the Pellegrin Hospital, we formed two teams working on the microbiota: one works on immune-microbiota interactions; the other organizes meetings with internal and external speakers.
We attempt to propose a refined definition of the notion of tumor microenvironment, at the interface between cancer biology, developmental biology, immunology, and studies on angiogenesis.
We also explore the concept of cancer as a process of decohesion of the multicellular individual, an idea that combines cancer biology, immunology, developmental biology, evolutionary biology, and ecology. We investigate the role of the immune system as a system that maintains the cohesion of the biological individual, and how this process is disturbed in cancer.
With Maël Lemoine, we are interested in the connection between aging and cancer.
People from other labs involved: Andreas Bikfalvi (Inserm), Lucie Laplane (IHPST & IGR).
Philosophers of medicine have investigated the broader framework of concepts of health and disease, with very general terms such as ‘function’ and ‘dysfunction’, ‘reference class’, ’norms’, ‘risk factor’, and the like. They have not investigated so much the more specific concepts of the biological sciences of health and disease, such as ‘homeostasis’, ‘robustness’ or ‘regulation’.
More specifically, we focus on the strong association, at the population level, of the process of aging and the incidence of diseases. To do that, we investigate concepts such as ‘antagonistic pleiotropy’, ’senescence’, ‘intrinsic factor of death’, and explanatory hypotheses, models and theories of aging.
Cancer is one of the diseases that come with aging. At the epidemiological level, age is the most ‘explanatory’ factor of most cancers. However, this remains vague and elusive at the biological level. Which processes are associated with an increasing risk of cancer? We look for a conceptually precise theory of aging that would help understand the patterns of incidence of cancer.
Beyond that, we hope this theory to be able to also account for patterns of incidence of other diseases.
This project is coordinated by Maël Lemoine, Professor at the University of Bordeaux.
Participants are Jean-François Moreau, Simon Okholm
Our group is a pillar of the Institute for Philosophy in Biology and Medicine (PhilInBioMed), an interdisciplinary institute located at the University of Bordeaux, France, and a national and international network of interdisciplinary institutes. PhilInBioMed aims at promoting philosophy in the biological and medical sciences.
