PhD project description

Plasmacytoid dendritic cells (pDCs) are hematopoietic cells characterized by their unique ability to rapidly produce very large amounts of type I and III interferons in response to viral-type stimuli (Reizis, 2019). The identity of pDCs is ambiguous, as they possess a specific molecular identity card conserved between mouse and human, while sharing characteristics with both classical DCs (cDCs) on the one hand and lymphocytes on the other hand (Reizis, 2019). The balance between these three identity components varies according to the activation state of pDCs (Abbas et al., 2020). There is also controversy about the physiological functions of pDCs, including whether they play a beneficial role in the immune control of viral infections or a deleterious role in the development of certain autoimmune diseases.

Aims of this project

The global objective of the thesis project will be to perform bioinformatics analyses of genomic data to elucidate the ambiguous identity of pDCs and to infer hypotheses on their physiological role.

  • Specific Aim 1: Determine the positioning of pDCs within an immune cell atlas.
    • Specific Aim 2: Elucidate the molecular mechanisms of regulation of pDC identity.
    • Specific Aim 3: Elucidate the molecular mechanisms of pDC activation from virus-like stimuli.
    • Specific Aim 4: Analyze human genetic polymorphisms in the pDC genome and to look for a link with pathologies.
