🦟🌳 Déforestation et santé : en forêt atlantique, les #moustiques de + en + attirés par l’humain à mesure que les habitats naturels se fragmentent.
Une évolution discrète, mais majeure quant au risque d’arboviroses comme la #dengue ou #Zika.

Discovery of a potent anti-#zika virus benzamide series targeting the viral protein NS4B by Donghoon Chung, Yuka Otsuka, Eunjung Kim, Sultan Ullah, Nicole M. Kennedy, Khac Huy Ngo, Jinjoo Kang, Reece Tomlinson, Brian Alejandro, Koji Barnaby, Jeffrey Miller, Justin Shumate, Chwee Fang Teo, Yaw Bia Tan, Che Shin Chew, CongBao Kang, Dahai Luo, Louis Scampavia, Timothy P. Spicer, Thomas D. Bannister Zika virus (ZIKV), a member of the Flaviviridae family, causes significant public health concerns through congenital Zika syndrome and Guillain-Barré syndrome, yet no effective anti-ZIKV drugs or vaccines are available. To address this critical need, we conducted phenotypic, cytopathic effect-based high-throughput screening followed by medicinal chemistry optimization and discovered novel benzamide anti-ZIKV leads. Current best compounds demonstrated superior potency (EC50 values 40–400 nM, CC50 > 50 µM) compared to NITD-008, the most potent known anti-ZIKV agent. Time-of-addition assays, resistant virus selection studies, and biophysical binding experiments confirmed that NS4B interference constitutes the primary antiviral mechanism. Notably, resistance mutations mapped to the C-terminus of NS4B, distinct from other flavivirus NS4B inhibitors targeting dengue or yellow fever viruses, revealing novel insights into a critical function of the region. These findings establish NS4B as an Achilles’ heel for flaviviruses and support the development of pan-flavivirus therapeutics targeting this essential viral protein.

Immune mechanisms of congenital Zika syndrome This Review discusses both fetal and maternal immune responses that influence the development of congenital Zika syndrome.

Prenatal Zika virus exposure disrupts social-emotional development and cortical visual function in infant macaques - Nature Communications Prenatal Zika virus (ZIKV) exposure can lead to a spectrum of developmental issues, but the mechanisms remain unclear. Here the authors show that prenatal ZIKV exposure in macaques disrupts neurodevelopment, causing prolonged maternal attachment and visual deficits at 3 months that normalize by 12 months, independent of sensory function.

Remember Zika? It didn't vanish. It's still affecting lives in Africa, So, we're demanding it get the attention it deserves. Join our #ZikaStillLivesHere campaign. Let's break the silence and make a difference. #Zika #GlobalHealth #WHO #MicrocephalyInAfrica

Forest loss is driving mosquitoes’ thirst for human blood In the rapidly disappearing Atlantic Forest, mosquitoes are adapting to a human-dominated landscape. Scientists found that many species now prefer feeding on people rather than the forest’s diverse wildlife. This behavior dramatically raises the risk of spreading dangerous viruses such as dengue and Zika. The findings reveal how deforestation can quietly reshape disease dynamics.
