Neurocognitive impact of Zika virus infection in adult rhesus macaques.

Background: Zika virus (ZIKV) is a mosquito-transmitted flavivirus that affects many regions of the world. Infection, in utero, causes microcephaly and later developmental and neurologic impairments. The impact of ZIKV infection on neurocognition in adults has not been well described.

TLR7 agonist, N6-LS and PGT121 delayed viral rebound in SHIV-infected macaques after antiretroviral therapy interruption.

Toll-like receptor 7 (TLR7) agonist and PGT121 (broadly neutralizing antibody, bnAb) administration previously delayed viral rebound and induced SHIV remission. We evaluated the impact of GS-986 (TLR7 agonist) and dual bnAbs on viral rebound after antiretroviral therapy (ART) interruption. Rhesus macaques inoculated with SHIV-1157ipd3N4 were initiated on daily suppressive ART from Day 14 post SHIV inoculation.

Pinostrobin suppresses the Ca2+-signal-dependent growth arrest in yeast by inhibiting the Swe1-mediated G2 cell-cycle regulation.

Pinostrobin, a flavonoid compound known for its diverse pharmacological actions, including anti-leukemic and anti-inflammatory activities, has been repeatedly isolated by various screenings, but its action mechanism is still obscure. Previously, pinostrobin was rediscovered in our laboratory using a yeast-based assay procedure devised specifically for the inhibitory effect on the activated Ca2+ signaling that leads the cells to severe growth retardation in the G2 phase. Here, we attempted to identify target of pinostrobin employing the genetic techniques available in the yeast.

Impact of analytical treatment interruption on the central nervous system in a simian-HIV model.

Objective(s): Analytical treatment interruption (ATI) studies are often used to evaluate potential HIV cure strategies. This study was conducted to determine the impact of ATI on simian-HIV (SHIV) infection in the central nervous system.

Design: Animal study.
