Magdalini Lourda team – Innate immune system in cancer, inflammation and infection

Our team studies the role of the innate immune system in acute and chronic inflammatory diseases in children and adults, with focus on Langerhans cell histiocytosis (LCH), psoriasis, inflammatory bowel disease and COVID-19.

The Magdalini Lourda team is connected to the Anna Norrby-Teglund and Mattias Svensson research groups at the Center for Infectious Medicine (CIM).

The team's focus

In our team, we integrate various advanced experimental approaches to identify disease-specific subpopulations of granulocytes in blood and tissues of patients and understand how the granulocytes interact with other immune and stroma cells contributing to disease pathology.

Granulocytes constitute the first line of defense against pathogens and their role was long considered to be restricted to the initial, acute phase of the inflammatory responses. Although inflammation is necessary to confer protection to the host from exogenous pathogens and initiate repair mechanisms of the damaged tissue, granulocytes can also generate enormous collateral damage in the process of pathogen elimination, which may lead to chronic pathologies. Despite their importance in modulating adaptive immune responses, the specific phenotype and function of granulocyte subpopulations in different human tissues and diseases is not well understood.

Team leader

Magdalini Lourda

PhD, Senior Researcher

Magdalini completed her PhD in the National and Kapodistrian University of Athens (Greece) and then moved to Sweden to work as a post-doc at the Center for Infectious Medicine, in collaboration with the Department of Women’s and Children’s health, KI.

During her post-doc, she studied the involvement of myeloid cells in the pathogenesis of granuloma diseases, such as Langerhans cell histiocytosis (LCH) and Crohn’s disease. Her research resulted in the identification of several disease-associated deregulated molecular and cellular processes and contributed to new tools for diagnosis, monitoring and treatment of patients with LCH.

Magdalini became an Assistant Professor in 2015.

Team members

Avinash Padhi

PhD, Postdoc

Avinash obtained his PhD from Kalinga University (India) in 2019 on host pathogen interaction in tuberculosis, focusing primarily on macrophages. He then moved to Sweden to pursue post-doctoral training, studying the role of neutrophils and keratinocytes in skin inflammation.
