Petter Brodin is Professor of pediatric immunology at Imperial College London and at Karolinska Institutet in Stockholm, Sweden. The Brodin lab (https://brodinlab.com/) develops and applies novel experimental and computational methods to describe human immune system variation with a particular interest in the immune systems of children, its development early in life, and its role in health and disease during childhood.
After completing a MD/PhD program at the Karolinska Institutet, Brodin joined the Mark M Davis’s laboratory at HHMI, Stanford University School of Medicine as a postdoctoral fellow, investigating the contribution of heritable and non-heritable sources of variation in immune systems of twins (Brodin et al, Cell, 2015). Following this, Brodin returned to Sweden to establish a national facility for immunomonitoring at the Swedish infrastructure hub, Science for Life Laboratory. He also established his own research program applying systems-immunology methods to the study of immune system development early in life. The Brodin lab established a birth cohort and showed differences in early life adaptation between preterm and term infants (Olin et al, Cell, 2018), the global repertoire of maternal antiviral antibodies (Pou et al, Nat. Med, 2019) as well as the imprinting effect of select colonizing microbes such as bifidobacterial early in life (Henrick et al, Cell, 2021). The Brodin lab has also applied its technologies for systems-level immune system analysis during the COVID-19 pandemic to understand COVID-19 in children (Brodin, P, Immunity 2022), the immunology of MIS-C (Consiglio et al, Cell, 2020), LongCOVID (Brodin et al, Nature Medicine, 2022), and severe COVID-19 (Rodriguez et al, Cell Reports Med, 2020) and are active members of the global COVID-Human Genetic Effort (https://www.covidhge.com/).
Petter will be speaking on immune system regulation and dysregulation in Covid-19

HLH Symposium Presenters
Ulf Anderson has served as a pediatrician in Stockholm since 1974, mainly as a pediatric rheumatologist. In parallel he performed basic studies in inflammation and immunology at Stockholm University and the Karolinska Institute. His PhD project, defended in 1982, dealt with ontogeny studies of human lymphocyte functions. He then focused on cytokines, alarmins and interactions between the central nervous system and the immune system. His major scientific contributions: a) inventor of globally used cellular methods enabling quantification of individual cytokine/ chemokine-producing cells by flow cytometry or imaging technology (Immunol Rev 119:65, 1991); b) co-discoverer with Kevin Tracey in New York of the central role of extracellular HMGB1 as the prototypical alarmin molecule (Science 285:248, 1999); spent 25 years on studies of HMGB1 biology aiming to identify means to target HMGB1 in pathological inflammation; identifying HMGB1 as a neurotransmitter released from nociceptors directing inflammation (PNAS 118:e2102034118, 2021); c) explorative studies together with Kevin Tracey during the latest two decades on the the cholinergic anti-inflammatory pathway (Annu Rev Immunol 30:313, 2012). Extracellular HMGB1 promotes inflammation, while acetylcholine prevents HMGB1 release and inhibits inflammation. Vagus nerve stimulation, via invasive or non-invasive methods, thus offers exciting novel clinical opportunities to control challenging inflammatory diseases (J Intensive Med. doi.org/10.1016/j.jointm.2022.02.001, 2022).
Ulf will be presenting a talk entitled, "THE OUTCOME OF MACROPHAGE ACTIVATION SYNDROME IS DETERMINED BY AN INTERPLAY BETWEEN CELL DEATH MODE, HMGB1, AND ACETYLCHOLINE"

Dr. Sabrin Albeituni graduated in Biology from Birzeit University, Palestine and earned her PhD in Microbiology and Immunology in 2015 from the University of Louisville, KY. She then pursed her postdoctoral training in the laboratory of Dr. Kim Nichols at St. Jude Children’s Research Hospital in Memphis, TN. During her training she studied the mechanisms of JAK1/2 inhibition either alone or in combination with dexamethasone as a novel therapy for the treatment of HLH. She performed preclinical studies in murine models of HLH and found that the JAK1/2 inhibitor, ruxolitinib, ameliorates the clinical manifestations of disease in HLH through IFN-gamma dependent and independent mechanisms. Her work set the ground for a clinical trial that is being sponsored by St. Jude to use ruxolitinib for the treatment of HLH. Currently she is a Scientist in Dr. Nichols’ laboratory, and her main research focus is to investigate the cellular and molecular mechanisms governing the pathogenesis of HLH. In addition, she is working on finding novel targets to dampen inflammation in HLH.

C. Matthias Wilk
Matthias Wilk graduated from the University of Duesseldorf School of Medicine (Germany). Throughout his residency and clinical fellowships at the University Hospitals in Duesseldorf (Germany) and Zurich (Switzerland), Matthias was dedicated to experimental research in Hematology in addition to his clinical curriculum. Amongst others, Matthias studied the impact of Clonal Hematopoiesis on Long-Term-Survivors of Allogeneic Hematopoietic Stem Cell Transplantation and approaches to repurpose TPO agonists as chemosensitizers in Hematopoietic Stem Cell Transplantation. He also co-developed a humanized mouse model for Langerhans Cell Histiocytosis (LCH) that allows studying human LCH in a murine model suitable for drug testing. Fascinated by histiocytic disorders, Matthias then joined the laboratory of Miriam Merad at the Icahn School of Medicine at Mount Sinai in New York. In collaboration with the team of Carl E. Allen at the Texas Children’s Hospital in Houston, he is studying Neurodegenerative Disorders in LCH. Therefore, he developed different mouse models for histiocytic disorders that recapitulate key features of human neurodegenerative LCH. The models he developed do not only permit studies on the pathogenesis of neurodegenerative LCH but also allow testing therapeutic approaches for this condition.

John Pritchard Lecture on the Nikolas Symposium Speaker
Astrid van Halteren
Dr. Astrid van Halteren completed her master degree in Biomedical Sciences at the University of Amsterdam in 1991. After defending her PhD thesis in 1996 (Vrije Universiteit Amsterdam), she moved to the Leiden University Medical Center (LUMC), where she started to work in the hemato-oncology field before being introduced into the histiocytosis field in 2008. As a certified specialist in immunology, she became intrigued by the inflammatory component of histiocytosis lesions. Her research team has investigated characteristics of lesional T-cells, co-published on newly identified driver mutations, studied intracellular processing of neoantigens encoded by the most prevalent molecular alteration (BRAFV600E) and recently completed a multi-centre study addressing associations between the three most common mutations and clinical presentation of pediatric LCH. Two abstracts presenting the results of these studies have been nominated by the Histiocyte Society for the Nezelof Prize for best Basic Science (2015) and the Nesbit Prize for Best Clinical Science (2019). As off August 2022, she will be affiliated with the Centre for Histiocytic Disorders established at the Erasmus University Medical Center in Rotterdam, which is acknowledged by the ECD Global Alliance and the Dutch Federation of University Medical Centers. In this new position, she will implement molecular monitoring and central biobanking in conjunction to the diagnosis and treatment of adult histiocytosis patients. In addition, she will continue her research on the hematopoietic ‘cell-of-origin’, which is performed in close collaboration with the Princess Máxima Centre for Pediatric Oncology where she is appointed as co-PI. Her research aims at finding alternative ways to eradicate neoplastic stem/progenitor cells beyond conventional chemotherapy.
Astrid will be presenting an update on the proceedings from the 2022 Nikolas Symposium.

Dr. Julien Haroche is a professor in internal medicine, at Pitié-Salpêtrière hospital, Paris, France. Since 2003, his main research field is Erdheim-Chester disease (ECD) upon which he has acquired a word-renowned experience. To date, he has seen more than 380 patients followed at his institution. His other research fields are the other histiocytoses, such as Langerhans cell histiocytosis, mixed histiocytoses (LCH & ECD) and Rosai-Dorfman disease. He is also interested in vasculitis, systemic lupus and antiphospholipid syndrome.
During the past 15 years, he has described most relevant clinical and radiological aspects and increased the awareness of ECD; he has showed that interferon α was a first line efficient therapy. His team was the first to used targeted therapies in adult patients with histiocytoses in 2012. Since then more than 175 patients have received BRAF and/or MEK inhibitors at his institution.
