Sistema inmunitario (Immune system) (None)

The immune system is a complex, dynamic network of cells (e.g., T cells, B cells, NK cells, neutrophils, macrophages), molecules (antibodies, cytokines, complement proteins), and tissues (bone marrow, lymph nodes, spleen, thymus) that work together to identify and destroy pathogens, provide surveillance against cancer, and regulate inflammation and tissue repair[7][8][4][1]. It is divided into innate and adaptive branches, each consisting of specific cell types and molecular mediators that ensure effective defense against infection and disease[7][4][8]. The system includes numerous distinct therapeutic targets, but the system as a whole cannot be treated as a single molecular entity for drug development.
