The clinical implication or pathogenic consequences of brain amyloid deposition are still controversia
Molecules including major histocompatibility complex (MHC) II and CD40 [15]. Microglia expressing MHC II induce CD4+ T cells to generate IFN-g and TNF-a [16]. In the case of both HAD and AD, this response is considered harmful to the brain and in both diseases TNFa is elevated to neurotoxic levels while only in HAD is IFN-g is prominently elevated [14]. In HIV associated dementia (HAD; also known
Owed a direct correlation between microglial activation/infection and cognitive decline [19]. Studies have found microglial HIV infection as central in exacerbating HIV dementia [20,21]. Importantly, neuronal dysfunction and death in HIV infection results from cytokine stimulation, but especially several cytokine-mediated apoptotic mechanisms emanating from microglia. Thus microglial cytokine prod
Ctedwomen who used NVP-based highly active ART with CD4 counts higher than 350 cells/ .19 ART interruption exposes the HIV patient to risk of developing drug resistance. Proper use of antiretroviral therapy in HIV-1 infection enhances treatment outcomes and immunological recovery.LimitationsThe small sample size of pharmacies which were stocking ARVs is a limitation of this study.

Pectively, correspond to the type ii or iii microglial states described in the preceding paragraph. Further, the factors which cause polarization to M1 or M2, reinforce the maintenance of that phenotype in a cycle-like manner [8,9] (Figure 1). Increased M1 polarization is consistent with increased TNF-a observed in plasma and brain specimens in HAD and AD, and may play a role in the pathophysiolog
