Allege

A Toxicologist’s View of Immunotoxicology in their eagerness to test as many chemicals as possible, scientists often do not spend sufficient time studying the theoretical basis and medical relevance of their experimental models. Moreover, classical concepts of toxicology, e.g. the compulsory use of excessively high doses, are uncritically applied in the newly developed tests.

Mechanisms of Autoimmunityhat potentially autoreactive lymphocytes do exist in the intact, healthy immune system. Normally, however, these cells are controlled by mechanisms precluding their reactivity or, at least, precluding the development of harmful autoimmunity.

Primary Immunodeficienciesed to rapid advances. The finding of new defects has more than once revealed the existence of a particular cell, or a particular differentiation stage or a particular molecule. Animal models have been developed, lending themselves to more complete investigations and wider therapeutic trials.

Immunological Abnormalities in the Acquired Immunodeficiency Syndromehe District of Columbia, had been reported to the CDC (CDC weekly surveillance report on AIDS). Moreover, at least 700 cases had been documented in at least 33 countries outside of the United States (CDC, unpublished statistics).

The Role of Histopathology in Assessment of Immunotoxicityrent sites, e.g. the bone marrow or as suggested by Hall in this volume, in the lower gut) The secondary lymphoid tissue, in which the complex cellular interactions take place which form the basis of the immune response, includes the spleen, lymph nodes and the mucosa associated lymphoid tissues in the alimentary and respiratory tracts.

Experience with Validation of Methodology for Immunotoxicity Assessment in Rodentsindications for data transformation, a quality control program; correlations between altered immune function and susceptibility to bacterial or tumor cell challenge; the concept of a functional immune reserve and its estimation; and, the need for an international interlaboratory validation of methods.

Relationship Between the Immune System and Cancered rodent tumors to human cancer remains unresolved. This is principally because of the lack of appropriate methods for defining human tumour antigens and detecting specific immune responses to them in cancer patients. Contemporary studies on tumor cell-lymphocyte interactions will probbably provide a more acceptable approach to this problem.
