Immune System - JSON

The immune system is a complex biological defense system that protects the body from pathogens such as viruses and bacteria. It consists of two main mechanisms: innate immunity and adaptive immunity. Innate immunity is an immediate defense mechanism present from birth, with neutrophils, macrophages, and NK cells playing major roles. Adaptive immunity is an antigen-specific immune response acquired after birth, characterized by antibody production by B cells and cellular immunity by T cells. B cells mediate humoral immunity, producing antigen-specific antibodies that neutralize pathogens. T cells mediate cellular immunity, with CD4+ helper T cells coordinating immune responses and CD8+ cytotoxic T cells directly eliminating infected or cancerous cells. These immune cells work in coordination, forming immunological memory to enable rapid and effective defense upon re-exposure to pathogens.
