Marieke van Ham

Anja ten Brinke

The research group of Marieke van Ham and Anja ten Brinke has studied antigen-specific immune responses for more than 2 decades. The group specializes in fundamental and translational research studying both desired antibody responses against pathogens/vaccines as well as undesired immunogenicity against biological and self-antigens.

Key interests of the group are regulation of plasma cell differentiation through antigen-driven interactions between activated B cells and follicular Thelper (Tfh) cells. The group investigates regulation of antigen uptake and MHC-mediated antigen presentation and the differential regulation between proinflammatory (IgG1, IgE) and anti-inflammatory (IgG4) antibodies.

Studies on safety and efficacy of anti-tetanus hyperimmunisation programs of voluntary donors and alloimmunisation upon transfusion or red blood cells or platelets belong to current areas of research.

Finally, the group specialises in general and antigen-specific B and CD4 T cell immunomonitoring for therapy efficacy of immunomodulating drugs/biologics in national and international consortia (HORIZON2020).
