[Human infection immunology. Basic scientific findings and clinical consequences].
During the last years studies on human immune responses to specific micro-organisms have contributed to an increased understanding of the structure and function of the immune system. T lymphocytes with a special antigen receptor (gamma/delta cells) are thus probably important in some infectious diseases such as malaria and tuberculosis. The discovery of T-cell responses to protein-free fractions of mycobacteria and Leishmania parasites has lead to the identification of non-protein T-cell antigens. T-cells that express the CD4 receptor on their surface and are capable of lysing infected target cells have been found in viral infections. It has furthermore been found, that the composition of the signal mediators (cytokines) secreted by activated T-cells can determine the outcome of a number of infections. In the future it may be possible to include enhancement of protective immune reactions in the treatment of infectious diseases to a higher extent than now.
