Alzheimer's disease (AD) is a neurodegenerative disease with major clinical hallmarks of memory loss, dementia, and cognitive impairment. Neuroinflammation is involved in the onset of several neurodegenerative disorders. Astrocyte is the most abundant type of glial cells in the central nervous system (CNS) and appears to be involved in the induction of neuroinflammation. Under stress and injury...

osteopontin also known as bone sialoprotein (bsp). osteopontin role as a linking protein. it is an extracellular structural protein and therefore an organic component of bone. osteoprontin (opn) binds to several integrin receptors containing α4β1, α9β1, and α9β4 expressed by leukocytes. these receptors have been well-stable to function in cell adhesion, migration, and survival in these cells. i...

Parkinson’s disease (PD) is characterized by the loss of dopaminergic neurons in the substantia nigra, which progressively manifests into in a movement disorder. We propose a mechanism that describes the role that aggregated α-synuclein and neuroinflammation play in perpetuating a vicious cycle of neurodegeneration. A system of autonomous Ordinary Differential Equations (ODEs) is derived. Given...

Inflammation is the innate immune response to infection or tissue damage. Initiation of proinflammatory cascades in the central nervous system (CNS) occurs through recognition of danger associated molecular patterns by cognate immune receptors expressed on inflammatory cells and leads to rapid responses to remove the danger stimulus. The presence of activated microglia and astrocytes in the vic...

With as many as 300,000 United States troops in Iraq and Afghanistan having suffered head injuries (Miller, 2012), traumatic brain injury (TBI) has garnered much recent attention. While the cause and severity of these injuries is variable, severe cases can lead to lifelong disability or even death. While aging is the greatest risk factor for Alzheimer's disease (AD), it is now becoming clear th...
