SEREX, Proteomex, AMIDA, and beyond: Serological screening technologies for target identification.
Despite the great body of knowledge about the aetiology, pathogenesis, risk factors, and associated molecular processes, cancer remains a prime health concern. Over the past decades scientific and medical research focused on the identification of biomarkers and target molecules for the diagnosis and therapy of cancer. Such markers may allow for improved and early diagnosis, as well as for immunotherapeutic approaches for cancer treatment. A plethora of technologies dedicated to the identification of target molecules was developed including those relying on a humoral response against tumour-associated antigens (TAA) in diseased individuals. As for other diseases, cancers elicit immune responses that result in the induction of T and B lymphocytes specific for tumour-associated proteins, largely self-antigens, but also those comprising viral and bacterial proteins. Cancer-specific serum antibodies are of great use for the isolation and subsequent identification of their cognate antigens. The present review will concentrate on three major serological target identification methods, i.e. SEREX, Proteomex, and AMIDA, concluding with a summary of the milestones in the clinical advancement and applications of serological TAA.
