Y and also visibly damaged subcortical areas [45,46]. Amyloid plaques in AD result from the deposition of amyloid beta (Ab) which is a putative pathogenic molecule in AD. Ab is the cleavage product of the amyloid precursor protein (APP) and APP mutations are associated with inherited forms of AD. The clinical implication or pathogenic consequences of brain amyloid deposition are still controversia
Ignificantly longer lives. While HAART has been increasing the lifespan of those infected with HIV, it has also led to an increased prevalence of HAD [32-38]. As the pathology of HAD, like Alzheimer's Disease (AD), is commonly characterized by an increase in the amount of amyloid-beta (Ab) peptide in the brain [39], evidence suggesting microglia modulate the clearance of potentially neurotoxic Ab
Vioral complications [66-69]. Microglia, as a major target of HIV-1 infection in the CNS, are typically a viral reservoir [70-72] and are also key in HIV-1 neuroinvasiveness-penetration into the CNS by the virus [72,73]. Most importantly, a discrepancy between the localization of HIV-infected cells and the severity of neurocognitive symptoms has been described [74-76]. Thus, other mechanisms secon
