| Open AccessHIV-1 RNA in extracellular vesicles is associated with neurocognitive outcomes
Despite effective antiviral drugs, HIV-1 transcripts can be found in extracellular vesicles (EVs) in people living with HIV-1. Comparing EVs from serum and cerebrospinal fluid (CSF), the authors show compartmentalized defective viral transcripts that are enriched in the CSF and corelate with cognitive dysfunction.

| Open AccessPost-resolution macrophages shape long-term tissue immunity and integrity in a mouse model of pneumococcal pneumonia
The post-resolution phase of inflammation is not simply a linear path towards cessation of immune response but rather a regulated process involving fluctuating immune activity. Here authors show a pivotal role for post-resolution macrophages in driving a wave of T cell recruitment and activation via prostaglandin E2 and α-integrin signalling during the resolution phase of murine pneumococcal pneumonia.

| Open AccessThe sterol C-24 methyltransferase encoding gene, erg6, is essential for viability of Aspergillus species
Antifungal triazoles inhibit biosynthesis of ergosterol, a crucial component of the fungal plasma membrane. Here, Xie et al. show that Erg6, the enzyme that catalyzes a previous step in ergosterol biosynthesis, is essential for the viability of Aspergillus fumigatus, and its repression reduces the virulence of this fungal pathogen in an animal model of infection.

| Open AccessPopulation pharmacokinetic modelling of primaquine exposures in lactating women and breastfed infants
Primaquine treatment for breastfeeding mothers is currently not recommended. Here, the authors develop a pharmacokinetic model to predict drug exposure of infants and show that ingesting breastmilk from mothers treated with primaquine results in <1% of maternal drug exposure. This suggests that primaquine should not be restricted in post-neonatal breastfeeding women as standard doses are unlikely to cause adverse events in infants.
