Immunology explores the molecular and cellular networks that enable organisms to distinguish self from non-self, neutralize pathogens, and maintain tissue homeostasis. The immune system comprises innate and adaptive branches, each with specialized roles. Innate immunity provides immediate, nonspecific defense via phagocytes, complement proteins, and cytokines, while adaptive immunity delivers antigen-specific responses mediated by T and B lymphocytes. Central to this duality is antigen presentation, wherein dendritic cells process and display foreign peptides to activate T cells, initiating targeted effector functions such as antibody production or cytotoxic killing.
When immune regulation fails, pathologies emerge. Autoimmune disorders arise from aberrant self-antigen recognition, as seen in rheumatoid arthritis or lupus. Allergic hypersensitivity involves excessive IgE-mediated responses to innocuous antigens, while immunodeficiencies compromise host defense, increasing susceptibility to infections. Chronic inflammation, driven by unresolved immune activation, underpins conditions like inflammatory bowel disease and atherosclerosis. Key molecular mediators—cytokines (e.g., IL-6, TNF-α), chemokines, and immune checkpoints (e.g., PD-1, CTLA-4)—orchestrate these processes, making them pivotal therapeutic targets.
Advancing immunology research hinges on dissecting signaling pathways and cellular interactions at high resolution. Technologies such as single-cell sequencing has illuminated mechanisms of immune evasion in cancer and infection. Novel modalities like monoclonal antibodies, CAR-T cells, and checkpoint inhibitors exemplify translational successes derived from foundational discoveries.
