An immunogenetic view of delayed type hypersensitivity.
This review, the third in the series on cellular immune reactivity to tubercle bacilli in the centenary year of Koch's classical paper describing this phenomenon and its possible implications, represents an immunogenetic point of view. In fact this will be quite a broad point of view by an immunogeneticist who is not hampered by specific knowledge on therapy or prevention of tuberculosis. In this respect I probably do not differ very much from Robert Koch 100 years ago! An important difference, however, is that we think we now understand a great deal of the cellular and molecular basis of the immunological phenomena observed by Koch. Immunogenetics has contributed considerably to our current understanding and I will try to review that contribution here. Because thus far my main research interest has been in another mycobacterium, namely Mycobacterium leprae, I will use M. leprae and leprosy as an example to illustrate some ideas. The message of this review is that there is a reason for optimism: the knowledge recently gained by cellular and molecular immunologists as well as immunogeneticists has straightforward implications for the rational development of subunit vaccines and immunotherapeutic strategies.
