Used acyclovir or valacyclovir during study follow-up.HSV-2 prevalenceOf the 2,499 participants, 1383 (55.3 ) tested negative for HSV-2 at baseline, 892 (35.7 ) tested positive, 223 (8.9 ) had indeterminate tests, and one test was not done. Of the 223 with indeterminate tests at baseline, 114 (51.1 ) tested positive for HSV-2 infection at some point during follow-up. Factors associated with testin

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

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
