Article Synopsis
  • - Monocytes may contribute to HIV-associated neurocognitive disorder (HAND) by transporting HIV to the brain and releasing inflammatory cytokines, impacting cognitive function.
  • - A study found that levels of interleukin-8 and monocyte chemoattractant protein-1 were significantly higher in HAND patients compared to those with normal cognition, both at the start and after one year of antiretroviral therapy.
  • - Higher cytokine levels correlated with the amount of HIV DNA in monocytes, indicating that both the size of HIV reservoirs and monocyte inflammatory responses play a role in the persistence of HAND.

Since the 1940s, the large animal model to assess novel causal prophylactic antimalarial agents has been the Plasmodium cynomolgi sporozoite-infected Indian-origin rhesus monkey. In 2009 the model was reassessed with 3 clinical standards: primaquine (PQ), tafenoquine (TQ), and atovaquone-proguanil. Both control monkeys were parasitemic on day 8 post-sporozoite inoculation on day 0.

Immune sera from volunteers vaccinated in a blinded Phase 3 clinical trial with JE-VAX(®) and a new Japanese encephalitis virus (JEV) vaccine (IC51 or IXIARO), were tested for the ability to protect mice against lethal JEV challenge. Sera from IXIARO vaccinated subjects were pooled into four batches based on neutralizing antibody measured by plaque reduction neutralization test (PRNT(50) titer): high (∼200), medium (∼40-50), low (∼20) and negative (<10). Pooled sera from JE-VAX(®) vaccinated subjects (PRNT(50) titer∼55) and pooled JEV antibody negative pre-vaccination sera were used as controls.
