Cell Biology

We usually get “childhood diseases” only once and thereafter, we are protected from them by an “immunological memory” for the rest of our lives. In inflammatory rheumatic diseases the immunological memory is directed against the patient’s own body. Our group is investigating how memory lymphocytes control chronic inflammation, how they contribute to therapy refractoriness, and how we can target them, at best selectively.

In the past, we have identified memory plasma cells secreting pathogenic autoantibodies as a critical driver of chronic rheumatic, antibody-mediated inflammation, and as an unmet therapeutic target, a cell that is refractory to conventional therapies. Memory plasma cells secrete copious amounts of (auto-) antibodies and persist in dedicated niches organised by stromal cells in the bone marrow and inflamed tissues. We have now analysed how stromal cells maintain plasma cells in more detail. Direct contact between stromal cell and plasma cell activates the PI3 kinase signalling pathway in memory plasma cells, inactivating Foxo1/3, and preventing apoptosis induced by mitochondrial (metabolic) stress, i.e. activation of caspases 3 and 7. A second signal, provided by the cytokine APRIL, and mediated by the NFkB signaling pathway, is required to prevent apoptosis induced by stress of the endoplasmic reticulum, i.e.  activation of caspase 12. The cell-contact dependency of plasma cell persistence raises the question whether protective and pathogenic plasma cells may differ in the molecular composition of the contact, as already indicated by the work of the Tokoyoda group at the DRFZ, offering therapeutic options for the selective ablation of pathogenic plasma cells.

Memory B lymphocytes are the precursors of memory plasma cells and an essential component of the reactive immunological memory. Surprisingly little is known about them. We have now determined that switched memory B cells survive in spleen and bone marrow, and at least in the bone marrow, they are docked on to stromal cells similar to memory plasma cells. Single cell transcriptome and antibody repertoire analyses identified six different switched memory B cell populations. The functional roles of these populations and their relation to pathogenic memory B lymphocytes of rheumatic inflammation remains to be clarified.

A third type of memory lymphocyte is the memory T lymphocyte. These cells essentially control immune reactions, e.g. they are required for the generation of memory plasma cells. Again, a substantial fraction of protective memory T lymphocytes is maintained in the bone marrow, individually docked on to stromal cells. Pathogenic memory T lymphocytes, on the other hand, are found primarily in inflamed tissues of patients with rheumatic diseases. They secrete cytokines and chemokines, which stimulate inflammatory reactions and attract and activate granulocytes and phagocytes, inducing and maintaining chronicity of inflammation. In order to survive in the hostile environment of an inflamed tissue, pathogenic memory T lymphocytes have to adapt to the milieu. One such critical adaptation is the expression of  the transcription factor Twist1. Twist1 promotes the survival by inducing expression of the microRNA miR-148a which downregulates the pro-apoptotic factor Bim. In children with Juvenile Idiopathic Arthritis, in particular PD1+ T helper cells isolated from the synovial fluid express TWIST1. And here we can show that Twist1 also regulates the energy metabolism of pathogenic Th cells, making them entirely dependent on fatty acid oxidation. Molecular adaptations of pathogenic memory T lymphocytes thus qualify as unique targets for their selective therapeutic ablation.
