Human innate lymphoid cell lab – Jenny Mjösberg group

The research conducted in the Jenny Mjösberg group aims to characterize the role for innate lymphoid cells (ILCs) in intestinal inflammation, cancer and athma. Our research objective is ultimately to increase the understanding of disease mechanisms, discovering novel treatment targets and strategies for patient stratification in biologics treatment.

The group is part of the Center for Infectious Medicine (CIM).

About our research

Innate lymphoid cells (ILCs) serve as first-line tissue sentinels, integrating stromal- and immune-cell derived signals to monitor homeostasis, respond to infections and contribute to tissue repair at barrier surfaces such as the lung and gut. More and more data indicate that they might also be involved in disease, such as inflammatory bowel disease (IBD) and cancer in the gut, as well as inflammation in the airways (asthma). We perform internationally leading clinical and translational lung and allergy research in the Clinical Lung and Allergy Research Unit (CLARU).

We are trying to gain insight into basic ILC biology; how these cells are differentiated, regulated and interact with other cells in the immune system. We perform these studies in the context of gut and lung inflammation and gut cancer with the ultimate aim of increasing the understanding of disease mechanisms, discovering novel treatment targets and strategies for patient stratification in biologics treatment.

Translational research

Our research is set up in a truly translational fashion, where we address complex immunological questions in unique tissue material from patients with inflammation or tumors. For this, we use advanced single-cell based techniques such as flow cytometric analysis and sorting, in vitro cell assays as well as several molecular techniques including single-cell RNA-sequencing and ATAC-seq.

Single-cell analysis of intestinal lymphocytes reveals targets for treatment of inflammatory bowel disease

Inflammatory bowel disease (IBD) constitutes an increasing global health burden, yet effective treatments are lacking. Here we use single-cell RNA-sequencing and functional assays to dissect the human intestinal lymphocyte compartments in IBD. With this approach, we will determine parallels between known and novel subsets of tissue-resident, inflammation-associated, innate and adaptive lymphocytes to reveal therapy targets. Building on this characterization, we will perform longitudinal assessments of intestinal lymphocytes from IBD patients on biological treatments to unveil immunological signatures of treatment response and unfold critical disease mechanisms.

Single-cell proteomics and transcriptomics characterization of innate and adaptive lymphocytes in colorectal cancer and peritoneal carcinomatosis

Every year about 6000 Swedes are diagnosed with colorectal cancer (CRC) of which around 30% develop peritoneal carcinomatosis (PC). We have previously reported disturbances in the composition of ILCs in IBD and CRC. However, the role of intratumoral ILCs and the functional parallels between ILCs and T cells in PC is unknown. To this end we are performing multidimensional single-cell analysis of proteins and transcripts in ILCs and T cells to reveal the characteristics, heterogeneity and functional parallels between ILCs and T cells which will advance our understanding of anti-tumor immunity.

Tissue-specific regulation of human ILC2 in allergy and asthma

Asthma affects over 300 million people globally and causes approximately 150 deaths in Sweden every year. We recently demonstrated a rapid accumulation of activated innate lymphoid cells type 2 (ILC2) in bronchioalveolar fluid following allergen-provocation in humans. The overall aim of this project is to determine the role for ILC2 in asthma with particular focus on how the microenvironment regulates ILC2 function and plasticity and the effect of novel biological treatments on ILC2.

Defining the metabolic signatures of tissue- and tumor-resident ILCs

Induction of any immune response requires metabolic changes. While a number of genes and pathways have been evaluated in T cells, the factors that link activation to alterations in metabolic state remains to be profiled in depth for human ILCs. Using the latest techniques in metabolic profiling and single cell mutli-omics we aim to map the metabolic profiles of human ILCs across a range of tissues and inflammatory conditions and assess whether biological therapies can impact upon cell intrinsic metabolism. We are also seeking to determine how host metabolic state (e.g. obesity) can alter the ILC phenotypes during asthma. PI: Chris Tibbitt.
