Immune mechanisms

Immune mechanisms refer to the vast and integrated biological processes and cellular pathways through which an organism identifies and neutralizes foreign pathogens, abnormal cells, and toxins (Janeway et al., 2001). These mechanisms are broadly categorized into innate immunity, providing immediate and non-specific protection, and adaptive immunity, which involves antigen-specific recognition and the development of long-term memory (Abbas et al., 2021). Key components of these mechanisms include the activation of specialized cells such as T-lymphocytes and B-lymphocytes, the production of signaling molecules like cytokines, and the deployment of the complement system (NIH, 2023). While these pathways are the functional basis for therapies like checkpoint inhibitors, monoclonal antibodies, and vaccines, 'Immune mechanisms' itself is a broad biological concept rather than a specific molecular target like a single receptor or enzyme (StatPearls, 2023). Consequently, this entry is considered a high-level physiological category that encompasses thousands of individual therapeutic targets across various disease states, including oncology and immunology.
