Overview

Antigens are molecular structures, typically proteins, polysaccharides, lipids, or nucleic-acid complexes, that are recognized by the adaptive immune system and capable of eliciting a specific immune response. The precise region bound by an antibody or a T-cell receptor is the epitope, while the broader molecule may carry many distinct epitopes. Antigens are classified by origin and context: self-antigens normally tolerated by the host; non-self microbial and vaccine antigens; tumor-associated and oncofoetal antigens such as alpha-fetoprotein that re-emerge in malignancy; and alloantigens, notably the human leukocyte antigen (HLA) system, which governs transplant compatibility and donor-specific antibody responses. T cells recognize peptide antigens only when processed and displayed on major histocompatibility complex (MHC) molecules, whereas B cells can bind native conformational antigens and, with helper signals, differentiate to secrete antibodies. This recognition underpins protective immunity and is harnessed in vaccination, where defined antigens, often combined with adjuvants, prime durable responses. Antigens also drive immunodiagnostics and immunomonitoring, including assays of immune responses to vaccination and infection, and inform cancer immunotherapy and transplantation immunology. The journal publishes peer-reviewed research spanning vaccine and tumor antigens, antibody generation including single-domain and monoclonal antibodies, and HLA and donor-specific antibody responses in transplantation.
