Historically neurodegenerative diseases, Alzheimer's disease (AD) in particular, have been viewed to be primarily caused and driven by neuronal mechanisms. Very recently, due to experimental, genetic, and epidemiologic evidence, immune mechanisms have entered the central stage and are now believed to contribute significantly to risk, onset, and disease progression of this class of disorders. Although immune activation of microglial cells may over time engage various signal transduction pathways, inflammasome activation, which represents a canonical and initiating pathway, seems to be one of the first responses to extracellular β-amyloid (Aβ) accumulation. Here we review the current understanding of inflammasome activation in AD.-Venegas, C., Heneka, M. T. Inflammasome-mediated innate immunity in Alzheimer's disease.

Little is known about the inflammasome beyond its function in innate immune response. In this issue of Immunity, Tyrkalska et al. report that the inflammasome regulates the balance between erythroid ...
Neurological disorders occur in the central and peripheral nervous system and include Alzheimer's disease, stroke, and spinal cord injury. Activation of the innate immune system inevitably occurs in a...
Autophagy is a major intracellular digestion system that delivers cytoplasmic components for degradation and recycling. In this capacity, autophagy plays an important role in maintaining cellular home...
Alzheimer's disease (AD) is the most common form of dementia in the elderly and, despite the tremendous efforts researchers have put into AD research, there are no effective options for prevention and...
Alternatively activated macrophages are essential effector cells during type 2 immunity and tissue repair following helminth infections. We previously showed that Ym1, an alternative activation marker...

A secretory proteinase inhibitory protein that was initially purified from human SKIN. It is found in a variety mucosal secretions and is present at high levels in SPUTUM. Elafin may play a role in the innate immunity (IMMUNITY, INNATE) response of the LUNG.
Peptides and proteins found in BODILY SECRETIONS and BODY FLUIDS that are PROTEASE INHIBITORS. They play a role in INFLAMMATION, tissue repair and innate immunity (IMMUNITY, INNATE) by inhibiting endogenous proteinases such as those produced by LEUKOCYTES and exogenous proteases such as those produced by invading microorganisms.
Protection from an infectious disease agent that is mediated by B- and T- LYMPHOCYTES following exposure to specific antigen, and characterized by IMMUNOLOGIC MEMORY. It can result from either previous infection with that agent or vaccination (IMMUNITY, ACTIVE), or transfer of antibody or lymphocytes from an immune donor (IMMUNIZATION, PASSIVE).
A tripartite motif protein that consists of an N-terminal pyrin domain, a central coiled-coil region and B-box type ZINC FINGER, and C-terminal regions that mediate homotrimerization and interactions with other proteins (the B30.2/SPRY DOMAIN). It is expressed primarily by mature GRANULOCYTES and associates with the cytoskeleton in the perinuclear area as well as AUTOPHAGOSOMES, where it co-ordinates the assembly of AUTOPHAGY-RELATED PROTEINS and degradation of INFLAMMASOME components. It functions in INNATE IMMUNITY and INFLAMMATION; mutations in the Pyrin protein (MEFV) gene are associated with FAMILIAL MEDITERRANEAN FEVER.
The capacity of an organism to defend itself against pathological processes or the agents of those processes. This most often involves innate immunity whereby the organism responds to pathogens in a generic way. The term disease resistance is used most frequently when referring to plants.

Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
