Other successes of immunological research
- Development of therapeutic antibodies for the neutralization of pro-
inflammatory cytokines/cells to treat e.g. Rheumatoid Arthritis,
Multiple Sclerosis
- Treatment of cancer by using CAR-T-cells
- Immunodiagnostic for diagnosis of several diseases such as AIDS,
Leukemia, Borreliosis
- Deeper understanding of disease pathomechanisms
