Research group - Lennart Hammarström

Denna sida på svenska

We focus on two main areas of immunological research - Immunogenetics and Immunotheraphy.

Genetic basis of immunodeficiency diseases

Hyper IgM syndrome (HIGM)
Common variable immunodeficiency (CVID)
IgA deficiency (IgAD)

Expression of antibody encoding genes in

Lactobacilli (Rotavirus, Clostridium difficile, HIV)
Cytokines (IL-10, IL-21)
Ligands (CD40L)
