New blood test can distinguish between similar mosquito-borne viruses, thus contributing to better surveillance of how these infections spread #dengue #Zika #chikungunya @vyman.bsky.social @mtwhite.bsky.social

dlvr.itNew blood test may improve mapping of mosquito-borne virusesMosquito-borne viral diseases such as dengue, Zika and chikungunya are spreading to new regions as the climate becomes warmer. A new study from Karolinska Institutet and Institut Pasteur, published in Nature Communications, shows that a newly developed blood test can distinguish between similar viruses and thereby contribute to better surveillance of how these infections spread.

Proud co‑author on @cp-immunity.bsky.social study by Julius Lautenbach, @chrissundling.bsky.social & Team Färnert w/ HPA & @scilifelab.se. We integrate plasma proteome dynamics (1500 proteins) + scRNA-seq in acute malaria, identifying severity markers & exploring immune-cell communication.

cell.comSystems analysis of clinical malaria reveals proteomic perturbation and innate-adaptive crosstalk linked to disease severityWhile the immune response to Plasmodium falciparum malaria has been studied extensively, the circulating proteome and its cellular origins remain poorly characterized. Lautenbach et al. address this b...

ICYMI: New online! Chikungunya virus and other emerging arthritogenic alphaviruses

nature.comChikungunya virus and other emerging arthritogenic alphavirusesNature Reviews Microbiology, Published online: 07 May 2025; doi:10.1038/s41579-025-01177-8In this Review, Weaver and colleagues discuss the transmission cycles of arthritogenic alphaviruses, their vectors, epidemiology, transmission dynamics, evolution, pathophysiology and immune responses. They also outline strategies and countermeasures to anticipate and mitigate the impact of arthritogenic alphaviruses on human health.
