The Nold Laboratory follows the innovation value chain from basic science to product development; with our main focus in harnessing our expertise in immunology to explore the molecular mechanisms of several poorly understood and currently largely untreatable diseases that affect our tiniest patients, namely babies born prematurely. These diseases include bronchopulmonary dysplasia (BPD) that severely compromises lung function and entails pulmonary arterial hypertension (PAH), which in turn often causes right heart failure; intracranial haemorrhage (ICH) whose survivors commonly require extensive special education; and necrotising enterocolitis (NEC), a disease of the intestine that carries up to 70 per cent mortality (see review #8). Our aim is rapid translation of our findings into clinical medicine, as best exemplified by a planned clinical trial that is based on one of our discoveries (see paper #1 & 2 below) and that may establish the first safe and effective treatment for BPD.

Our laboratory’s second major focus lies on the new interleukin (IL-)1 family cytokines IL-37 and IL 38. Our revelation of the powerful anti-inflammatory properties of IL-37 (see paper #3 below), its signalling mechanisms, cell surface receptor (see paper #4 below) and discovery that homodimerization limits the anti-inflammatory effect of IL-37 (see paper # 5 below) has led to a surge of international interest in these previously largely obscure cytokines and revealed IL-37’s translational potential. Examples of our current work include exploration of the therapeutic potential of IL-37 in NEC (see paper #6 below), and the characterisation of IL-38 in health and disease, including in systemic lupus erythematosus (SLE) (see paper #7 below), an incurable autoimmune disease that affects women during their childbearing age and their unborn children.
