Leendertz: "Human health cannot be viewed in isolation"
Contact between humans and animals is becoming increasingly closer. This is due to the growing world population, the ever deeper intrusion of humans into natural habitats, the hunting of wildlife, and intensive livestock farming and agriculture. Combined with…
New vector vaccine against COVID-19 provides long-term protection
In 2022, researchers from the department “Viral Immunology” headed by Prof. Luka Cicin-Sain at the Helmholtz Centre for Infection Research reported on the novel vector vaccine for the first time. The promising immunogenic profile of the MCMV-based vaccine has now been…
Tuberculosis
Tuberculosis – a silent pandemic © HZI/Manfred Rohde Tuberculosis Tuberculosis is one of the „big three“ infectious diseases, together with AIDS and Malaria. In Europe, tuberculosis is almost forgotten, the times of the “The Lady of the Camellias” and…
Experimental Immunology
Immune cell populations are characterized by a high degree of heterogeneity to enable efficient and specialized responses to the diverse set of pathogens. This is particularly true for cells of the adaptive immune system, but also innate immune cell populations are heterogeneous and can adapt to different environmental conditions. Adaptation of immune cells is often associated with epigenetic alterations that lead to the fixation of gene expression patterns, finally resulting in cells with highly specialized fates, phenotypes and functional properties.
Innovative Organoid Research
Organoids are miniature models of human organs cultivated from stem cells in laboratory settings. These delicate tissue structures mimic the three-dimensional architecture and function of real organs, offering researchers a unique opportunity to enhance their understanding of biological processes. Our aim is to advance the development of highly complex organoids incorporating immune cells and vessels. By doing so, we establish a platform, especially for investigating infections, conducting vaccine tests, and innovating therapeutic approaches.
LncRNA and Infection Biology
RNA is a truly remarkable molecule with functions and activities far beyond that of an intermediate information carrier. The abundant class of long non-coding RNAs (lncRNAs) contains highly specialized RNA with structural or regulatory functions that range from assembling large protein complexes to localizing, sequestering, or allosterically modifying proteins and other interaction partners. Our genome contains thousands of lncRNAs, many of which are specifically regulated during bacterial or viral infections. However, their contribution to launching and sustaining an effective host response remains elusive. Our group combines a cutting-edge suite of technologies from the fields of biochemistry, genomics, molecular biology, and computational biology to decode how lncRNA work mechanistically and how they contribute to host defense mechanisms. This group is located at the Helmholtz Institute for RNA-based Infection Research (HIRI).

Computational Biology for Infection Research
The Department of “Computational Biology for Infection Research” studies the human microbiome, viral and bacterial pathogens, and human cell lineages within individual patients by analysis of large-scale biological and epidemiological data sets with computational techniques. Focusing on high throughput meta’omics, population genomic and single cell sequencing data, we produce testable hypotheses, such as sets of key sites or relevant genes associated with the presence of a disease, of antibiotic resistance or pathogenic evasion of immune defense. We interact with experimental collaborators to verify our findings and to promote their translation into medical treatment or diagnosis procedures. To achieve its research goals, the department also develops novel algorithms and software.
