Immunological Aspects of Endocrine Disease

Other potential cytotoxic mechanisms include the deposition of immune complexes of appropriate size in the stroma of the thyroid, followed by complement fixation and nonspecific inflammation; and the activation of macrophages in response to specific macrophage arming factor (Evans & Alexander 1970, Evans et al. 1972). In view of the number of interrelating ways whereby the immune system may exert an aggressive effect on a given tissue, it is perhaps not surprising that attempts to correlate one (e.g. antibody titres in the serum) or two (e.g.the release of lymphokines by T cells when incubated with appropriate antigen) immunological mechanisms with the severity or course of the disease in question have not met so far with conspicuous success. Perhaps we will only achieve this when we understand and can quantitate all or most of the immune mechanisms involved in a particular disease process and unravel their relative importance by correlating their presence with the natural history of the disease initially in its subclinical form.
