Reorganization and Remodelling
of immune cells

to communicate an effective immune response

Immune cells have a short period of time to orchestrate an adequate immune response upon infection. To ensure rapid and efficient communication, antigen-presenting cells and T cells (white blood cells) have developed a unique interface that supports rapid and efficient delivery of messages upon cell-cell interaction.

We use multifarious state-of-the-art microscopy techniques to study molecular mechanisms behind this effective cell-cell communication and discovered that cognate immune cell-cell interaction drives remodelling and reorganisation of:

(1) the 3D endocytic network (transport system of cells) - Figure 1.

(2) mitochondria (energy factory inside cells) - Figure 2.

(3) the nanoscaled organization of T cell receptors ('on'-button of T cells) - Figure 3.

(4) the plasmamembrane lipid and protein composition and 3D structure at the cell-cell interface.

Currently, we are targeting the various molecular mechanisms responsible for this T cell remodelling with the aim to be able to shape the response of

(a) regulatory T cell during transplantation, and

(b) boost helper T cell function during vaccination of elderly.
