Abstract:
The innate immune system plays diverse roles in health and disease. It represents the first line of defense against infection and is involved in tissue repair, wound healing, and clearance of apoptotic cells and cellular debris. Excessive or nonresolving innate immune activation can lead to systemic or local inflammatory complications and cause or contribute to the development of inflammatory diseases. In the brain, microglia represent the key innate immune cells, which are involved in brain development, brain maturation, and homeostasis. Impaired microglial function, either through aberrant activation or decreased functionality, can occur during aging and during neurodegeneration, and the resulting inflammation is thought to contribute to neurodegenerative diseases. This review highlights recent advances in our understanding of the influence of innate immunity on neurodegenerative disorders such as Alzheimer's disease, amyotrophic lateral sclerosis, Parkinson's disease, and Huntington's disease.

Introduction to Innate and Adaptive Immunity
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...
