Prof. Dr. Sarina Ravens participates in RESIST research projects B3 and B5.

My Research Interest in RESIST

We are interested in how the immune cells are shaped by environmental factors (e.g. microbiota, infections) during early childhood and how this can be linked to the susceptibility towards infections during life. 

We have recently developed a high-throughput sequencing technology and applied bioinformatics methods to analyze human T cell receptor repertoires in relevant patient cohorts. Within RESIST we will take advantage of the PRIMAL cohort (coordinated by D. Viemann) to understand how a defined microbiota, but also infections may influence the postnatal maturation, individual responsiveness and antigen receptor repertoire of T cells and B cells in preterm babies. We further aim at identifying new biomarkers to predict the susceptibility of individual patients against infectious diseases, which may finally improve current therapeutic strategies.
