About

Introduction

The Pulmonary Medicine Research Laboratory focuses on fundamental, translational and clinical research concerning the immunopathology of a range of respiratory disorders. In this context, there is a strong interest in the differentiation program of lymphoid cells in health and disease. One of the main aims is to characterize signal transduction pathways and specific transcription factors that induce lymphocyte activation and implement cell fate decisions at specific checkpoints. We explore the involvement of innate lymphoid cells and  various T cell subsets in type II immunity, particularly in allergic asthma in human and mouse models. T cell subsets are also studied in a range of other pulmonary disorders, including sarcoidosis, interstitial lung disease and respiratory infection. Furthermore, there is a specific emphasis on signal transduction pathways, in particular B cell receptor signaling, in B cell differentiation, autoimmune inflammation and interstitial lung disease (ILD). In our research, we use state-of-the art technology, including multi-color flow cytometry, multi-omics, imaging mass cytometry, as well as animal models.

Education and career

Rudi W. Hendriks studied Biology at the University of Utrecht, the Netherlands, and performed his PhD studies on X chromosome inactivation patterns in human X-linked immunodeficiency diseases in the Department of Immunohaematology at the Leiden University Medical Center (Prof. J.J. van Rood; Dr. R.K.B. Schuurman) in 1991. Next, he did a post-doctoral training in the Genetics Laboratory of the University of Oxford, UK, studying genetic aspects of X-chromosome inactivation. In 1993 he started his own line of research within the Department of Cell Biology and Genetics of the Erasmus MC (Head: Prof. Frank Grosveld) focusing on the developmental program of B and T lymphocytes in relation to immunodeficiency diseases, cellular activation and leukemia. This research line was continued in the Department of Immunology (Head: Prof. Rob Benner) from 1999 to 2007. After moving to the Department of Pulmonary Medicine in 2007, his research is mainly focused on unraveling the role of lymphocyte populations in chronic airway inflammation.   

 

Recent findings 

Both T helper 2 (Th2) cells and group 2 innate lymphoid cells (ILC2s) have been implicated in allergic asthma. Using animal models of house-dust mite (HDM)-induced allergic airway inflammation, we found that Notch-deficient Th2 cells do not accumulate in the lung, but are retained in the lung-draining lymph nodes. Transcriptome analysis revealed that Notch signaling licenses allergic airway inflammation by promoting Th2 cell lymph node egress via the KLF2/S1PR1 axis. In HDM-mediated airway inflammation in mice, ILC2s do not provide an early innate source of the pro-inflammatory cytokines IL-5/IL-13, but their activation is dependent on T cells. We observed that T cells and ILC2s are major effectors in influenza-induced exacerbation of HDM-induced allergic airway inflammation in mice. Upon virus clearance, ILC2s regained an activated phenotype and were major contributors to the type 2 cytokine milieu. Recently, we identified type 2 cytokine producing CD8+ T cells as well as an inflammatory CD45RO+ ILC2 subset as major effectors in severe, corticosteroid insensitive, asthma and during asthma exacerbation. Concerning our B cell work, we found that B cell receptor (BCR) signaling is aberrant in a range of systemic autoimmune disorders, pulmonary hypertension as well as pulmonary fibrosis. In particular, protein levels and phosphorylation status of the critical BCR signalling molecule Bruton’s tyrosine kinase (BTK) were increased in B cells. We observed that Btk inhibition – which has impressive efficacy in various B-cell malignancies and autoimmune disorders - induces unexpected.

In house-dust-mite-induced allergic airway inflammation, we found that ILC2 activation required T cells. Thus, in HDM-mediated airway inflammation in mice ILC2s do not provide an early innate source of IL-5/IL-13. Furthermore, the activation status of ILC2s was increased following influenza virus infection in mice, thereby likely contributing to inflammation-induced asthma exacerbation. Epigenetic analyses indicated that in circulating ILC2s ~80% of asthma-associated genes from GWAS were active, supporting a role for ILC2 in human asthma. In acute and chronic mouse models of HDM-mediated allergic asthma, we found that expression of Notch and its nuclear effector RBPJκ in T cells is essential for disease development. Mice lacking Jagged1/2 on DCs, T cells or lymph node stromal cells still developed HDM-driven airway inflammation. Importantly, hallmarks of asthma could be suppressed by the Notch inhibitory peptide SAHM1, which interferes with RBPJκ function. We also observed an increase in surface Notch1 and Notch2 positive TH2 cells in peripheral blood of asthma patients. Concerning our B cell work, we recently found that BTK protein levels and phosphorylation were increased in B cells from anti-citrullinated protein antibody (ACPA)-positive patients with rheumatoid arthritis, in Sjögren’s syndrome and in idiopathic pulmonary arterial hypertension.
