4.3Immune system Theimmune systemis a highly complex network of organs, cells, and molecules that defend the body against pathogens and cancer cells. It comprises innate and adaptive immunity. Dysfunctional immunity can lead to diseases like allergies, rheumatoid arthritis, and inflammatory bowel diseas...
The human immune system is a complex and fascinating network of cells, tissues, and organs that work together to defend the body against harmful invaders. It plays a crucial role in maintaining our health and well-being. The immune system consists of two main parts: the innate immune system ...

Interactions between the immune system and the nervous system have been described mostly in the context of diseases. More recent studies have begun to reveal how certain immune cell-derived soluble effectors, the cytokines, can influence host behaviour even in the absence of infection. In this Revi...
These different aspects of immune function are served by distinct kinds of secondary lymphoid organs and are shaped by factors in the local environment, such as dietary components and bacterial metabolites. Elucidating the factors that determine the anatomical compartmentalization of the intestinal immune ...
