Today, more than 80 specific autoimmune diseases are recognised, likely affecting over 5% of the Australian population.1 In terms of the economic burden they place on society, autoimmune diseases rank closely behind cancer, cardiovascular disease and respiratory disease.2 Fifty years ago, however, things were rather different. The concept of autoimmunity was still very much in its infancy, with many highly regarded clinicians and scientists dismissing the proposition out of hand.3

The seminal monograph Autoimmune diseases: pathogenesis, chemistry and therapy, written in 1961 by Australians Ian Reay Mackay and Sir Frank Macfarlane Burnet,4 has had an important influence on the recognition, acceptance and understanding of autoimmune disorders and was the first publication solely on the topic of autoimmunity. It was commissioned by American publisher Charles Thomas and first published in late 1962. Spanish and Japanese translations appeared in 1965 and 1967, respectively. The monograph was aimed at practising clinicians rather than at bench scientists and was written shortly after the publication of Burnet’s classic monograph The clonal selection theory of acquired immunity,5 which also provided a sound theoretical background for the existence of autoimmunity.

Sir Macfarlane Burnet, OM, AK, KBE, the senior author, was arguably one of the greatest medical scientists of the 20th century. He was born in Victoria in 1899, graduated MB BS from the University of Melbourne, and served as Director of the Walter and Eliza Hall Institute (WEHI) from 1944 to 1965. WEHI, established in 1915, is one of Australia’s leading research facilities, particularly in the fields of immunology, cancer and molecular biology. In 1960, Burnet was a co-recipient of the Nobel Prize in Physiology or Medicine. He died in 1985. The first author, Ian Mackay, AM, was born in Victoria in 1922 and also graduated MB BS from the University of Melbourne. He became head of the Clinical Research Unit of WEHI in 1963 and initiated a comprehensive study into autoimmunity.

In their 1962 monograph, Mackay and Burnet were able to define autoimmune disease “as a condition in which structural or functional damage is produced by the action of immunologically competent cells or antibodies against normal components of the body” and which arose by “the emergence of forbidden clones” of lymphocytes.4 The first three chapters were written by Burnet and provided definitions of immunological terms (a new language at that time), the theoretical background for normal immune responsiveness through clonal selection, and the mechanism for loss of immunological tolerance through the emergence of “forbidden” (autoreactive) clones. The next eight chapters were written by Mackay and detailed diseases that, in his opinion, were likely to be autoimmune. These diseases all had characteristic clinical or pathological markers of autoimmunity, including the presence of an autoantibody, hypergammaglobulinaemia, tissue deposition of immune complexes, lymphocytic and plasma cell accumulation in affected tissues, therapeutic benefit from corticosteroids, and overlap of differing autoimmune manifestations in the same patient (page 16).

Mackay and Burnet observed that autoimmunity may manifest in single organs or in a diffuse pattern, frequently shows a female predominance, and has a fluctuating course. They noted that genetic factors are also commonly seen, and initiating or triggering processes (eg, sunburn, viral and bacterial infections, chronic sepsis, pregnancy or drugs) could be identified in some patients (pages 19 and 263). The final two chapters included an analysis of therapeutic options — corticosteroids, cytotoxic drugs, antimalarial and other drugs, ionising radiation and surgical excision of lymphoid tissue.

Following the monograph’s publication, many reviews appeared in medical journals. Most praised the work, but not all — one in the Journal of the American Medical Association even questioned the timing, relevance and targeted audience for a book on “so-called ‘autoimmune’ diseases”.6 However, with the benefit of hindsight, we can now reflect on Mackay and Burnet’s insightful observations in this pioneering monograph and how they have influenced the progress made in the field in the 50 years since its publication.

Given the significance of diagnostic testing for autoantibodies that followed the publication of Autoimmune diseases, it is of some interest that this monograph was itself published more than 50 years after Donath and Landsteiner’s seminal description of the antibody-mediated autoimmune nature of paroxysmal cold haemoglobinuria.7 This observation and perhaps the serological investigations into the nature of the Wassermann and Forssman reactions8 were most likely to have contributed to Mackay and Burnet’s thinking on the pathogenesis of autoimmunity. Their singular insight was to implicate both the humoral and cellular immune systems in causing tissue damage, as was subsequently so clearly demonstrated through the newly emerging techniques of direct and indirect immunofluorescence.

Many common autoimmune disorders acknowledged today, such as systemic lupus erythematosus (SLE), rheumatoid arthritis and hyperthyroidism, were listed in the monograph. However, there were some notable exceptions, including type I diabetes mellitus, coeliac disease, autoimmune skin disorders (pemphigus, alopecia and vitiligo), antiphospholipid syndrome and the antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (Wegener’s granulomatosis and pauci-immune glomerulonephritis). Several diseases (eg, ankylosing spondylitis, inflammatory bowel disease and psoriasis) were listed as possibly immune — issues that can be considered unresolved today.

Mackay wrote prophetically (page 104):

Fifty years later, based on exhaustive experimental evidence from murine models of lupus, together with improved techniques for autoantibody recognition, our understanding of the genetic, environmental and stochastic factors operative in human lupus (and other autoimmune disorders) is indeed much enhanced.

Mackay also described what is now known as apoptosis, long before it was formally described by the Australian John Kerr and his colleagues in 1972,9 as well as the important role of apoptosis in the pathogenesis of SLE (page 100):

Mackay went on to write (page 101):

This appears to be early recognition of antigenic intermolecular spreading well before the concept was described.10

Burnet wrote, in relationship to the development of a forbidden clone (page 39):

Over subsequent decades, the existence of forbidden clones has become problematic, with research concentrating on disturbed homeostasis/immunoregulation (ie, a “release of a repression” in the Burnet parlance). Hence, in 1983, Sir Gustav Nossal (Burnet’s successor at WEHI) concluded:11

Later that year, even Mackay admitted that the emergence of a forbidden clone arising from somatic mutations in the repertoire of antibody-producing cells is “unlikely as a general explanation for autoimmunity”.12 However, a recent publication provides likely evidence of a clonotypic origin for a specific anti-Ro epitope in Sjögren’s syndrome/SLE.13 Perhaps Mackay and Burnet got it right after all.

Mackay and Burnet’s 1962 monograph is seen as a founding text and marked the beginning of autoimmunity as a clinical science. Its insightful concepts and novel ideas inspired a generation of clinical and basic immunological researchers. We salute Ian Mackay and Sir Macfarlane Burnet on the 50th anniversary of this seminal publication.
