About me

Professor of Viral Immunology at the Department of Medicine, Huddinge since 2013.

Research description

Innate and adaptive immune mechanisms work together to contain viral infections including human immunodeficiency virus 1 (HIV-1) and hepatitis C virus (HCV). We investigate basic aspects of cell-mediated immunity as well as the immunopathogenesis of these infections. We do this with a basis in our solid understanding of fundamental immunology that we apply towards patient-based research and develop into translational approaches. The majority of T lymphocytes carry diverse T cell receptors (TCRs) that display classical MHC-restriction. However, the T cell compartment also includes invariant T cell subsets that recognize antigens presented by non-classical MHC-like molecules. Several of these invariant T cell subsets are evolutionarily conserved, display innate-like characteristics, and play important roles in immune control of pathogens. The group is particularly interested in the role of adaptive T cell responses mediated by CD8 T cells, and in the role that innate-like T cells such as the invariant natural killer T (iNKT) cells and mucosa-associated invariant T (MAIT) cells play in host defense.
