Regenerative Immunology and Aging

Our work area is focusing on alterations of the immune system caused by the natural aging process, infections or diseases. We are interested in the cellular and molecular changes that cause the immune system to age. During aging, natural changes take place in the immune system making it vulnerable to infections or cancer and reducing vaccination efficiency. The mechanisms responsible for this reduced immunocompetence have not yet been identified - this is where our multidisciplinary research comes in. Our current and future projects focus primarily on clinical immunology, immune monitoring, immune-cell therapies and diagnostics.

The junior research group "T-Cell Immunity" from Dr. Marco Frentsch is assigned to our work area.

Research Focus

Age-related Changes in the Immune System

Despite intensive research, it is still unclear why immunocompetence is reduced in older people. It can most likely be ascribed to systemic causes which can vary from patient to patient. Together with systems biologists, we evaluate large volumes of data and examine the correlations. Taking this as a basis, we study the fundamental mechanisms of altered immunity in older people. Our goal is to allow people to age with dignity and in good health.

T-Cell Immunity

Organ transplant patients rely on long-term immunosuppression (i.e. permanent suppression of the immune response) to prevent organ rejection. These immunosuppressants inhibit efficient T-cell-mediated immunity against pathogens, such as viruses. In such cases, adoptive cell therapy with virus-specific T-cells from seropositive donors can be an effective treatment option in the clinical setting. Our aim is to selectively isolate antigen-specific T-cells according to activation-marker signatures with the help of recently developed methods. Magnetic-activated cell sorting (MACS) is a common technique for separating cells according to their surface markers. We were able to demonstrate that two surface markers (CD154 and CD137) are required for efficient targeted isolation of antigen-specific naïve T-cells.

Regenerative Therapies / Adoptive T-Cell Therapies

Regulatory T-cells (Tregs) can inhibit the activity of the immune system and are therefore the focus of adoptive T-cell therapies aimed to suppress unwanted immune responses, e.g. in autoimmune diseases. Hence, the isolation and enrichment of antigen-specific regulatory T-cells makes a valuable contribution to adoptive T-cell therapies. Our group's latest findings have shown that antigen-specific Tregs and conventional T-cells can be analyzed simultaneously, thus raising the possibility of new cellular therapies with antigen-specific Tregs.

CD8 Helper T-Cells

Furthermore, we work on a newly defined cell subtype: CD8 helper T-cells. Here, we are concentrating on CD8 T-cells that express CD40L, a main molecule for T-cell help. CD40L+ CD8+ T cells provide potent helper functions, such as APC activation and expression patterns which are similar to CD4 T-cells. This new CD8 T-cell subtype is a promising candidate for cellular immunotherapies, especially for treating tumors.

Flow Cytometry

We use classical flow cytometry – one of the key technologies used in conventional clinical diagnostics – in all our projects. The Core Unit "Flow Cytometry", led by Dr. Désirée Kunkel, has been integrated into our group since the BCRT was established.

Quantitative and qualitative immune analyses and the diagnostic techniques derived from these are at the heart of all our research interests. Our aim is to conduct basic research that can be easily translated to human diseases and applied in diagnostic and prognostic studies.
