Long-term impact of congenital Zika virus infection on the rat hippocampus: Neuroinflammatory, glial alterations and sex-specific effects.

Congenital Zika Syndrome (CZS) is a condition that arises when a neonate presents with abnormalities resulting from Zika virus infection during gestation. While microcephaly is a prominent feature of the syndrome, other forms of brain damage are also observed, often accompanied by significant neurological complications. It is therefore essential to investigate the long-term effects of CZS, with special attention to sex differences, particularly concerning hippocampal function, given its vulnerability to viral infections.

Development and validation of an all-in-one rabies virus Bat-Clade genomic sequencing and host identification protocol.

Rabies virus (RABV), remains a significant public health concern, with bat-maintained lineages accounting for all currently documented cases in Brazil. Despite the availability of pharmacological prophylaxis for humans and animals, the high genetic diversity of RABV in diverse natural bat hosts and continued circulation in multiple animals pose challenges for effective surveillance. Here, we developed and validated a novel, rapidly deployable amplicon-based sequencing approach for RABV genomic surveillance.

High glucose potentiates Zika virus induced-astroglial dysfunctions.

Zika virus (ZIKV) is a neurotropic flavivirus that induces congenital Zika syndrome and neurodevelopmental disorders. Given that ZIKV can infect and replicate in neural cells, neurological complications in adult brain are also observed. Glial cells may emerge to delay and/or prevent the development of ZIKV-induced neurodegeneration.
