Joachim Winter begin by stating a set of criteria which, if fulfilled, would satisfy us that a particular virus was the causative agent of a particular malignancy. These requirements will form the framework around which the topic will be developed. Of course, we do not wish to imply that these criteria are origin

Udo Schneidere by those of the future. Studies on the morphology, structure and biochemical properties of bacteria have provided us with much useful information, but even with the advent of computer-aided taxonomy, there is no satisfactory natural classification for bacteria. Although the number of characteristi

Melanie Lührmanns macrophages, T and B populations which may interact in performance of a response, and suppressor cells interfering with it. Accordingly, a lack of response may not necessarily indicate absence of immunocompetent cells, but rather nonexpression of competence. Thus, one should consider two possible

Konrad Zoz,Jens K?keof the immunogen. If the immunogen possesses different determinants the corresponding antibody species are synthesized, thus in the case of complex immunogens the response is made up of a mixture of several antibody populations with different specificities. These antibody populations appear simultan

Isabel G?ddelly, the concentration of a number of metabolites, a function of the amounts of enzymes involved in their synthesis or degradation, in turn retroacts on the rate of synthesis of these enzymes. The genetic bases for this regulation were established by JACOB and MONOD (1961). These authors also showed
