  Evaluation Summary:

  The manuscript by Lee and co-workers describes the development of 21 unique transgenic mouse lines that express optogenetic sensors and effectors in a cell lineage-specific fashion. The knock-in approach allows the sensors and effectors to be rapidly combined or moved to different backgrounds, such as genetic disease models. Such manipulations are often impractical when using a Cre-based system. This constitutes a vital advantage for many studies. The new mice described here will be very powerful tools to study physiology and alteration in disease models.

  Evaluation Summary:

  This is a rigorous and clearly written paper that provides quantitative data for the scope of intracellular signalling by ASIC channels. These channels are involved in pain signalling and other processes, and apparently can couple to intracellular pathways independent of ion flow. Here the authors measure the movements of the unstructured intracellular parts of ASIC using fluorescence spectroscopy coupled to functional measurements.

  Evaluation Summary:

  This paper is of interest to a broad audience in the blood coagulation and fibrinolysis field. Previously undescribed roles in a range of blood clot properties are attributed to a region of the clotting protein fibrinogen, using state-of-the-art methodology. The data support the main conclusions of the paper, open new avenues of investigation for understanding clot properties, and have clinical implications.

  Evaluation Summary:

  This is a well conducted study that examines the potential role of senescent cells in fracture healing. Furthermore, the authors have used senolytic agents to examine if targeting cellular senescence will have a significant impact on fracture healing phenotype. The manuscript is succinctly written, and the methods and results are well described. These data provide the first demonstration for a potential role for cellular senescence in regulating fracture healing. The authors’ conclusions are largely supported by the experimental data.

  Evaluation Summary:

  This study is of interest to the broad malaria research community and especially those who work on drug resistance. The authors provide a summary of their surveys of African and Southeast Asian Plasmodium falciparum parasites for the Kelch 13 gene, a marker of artemisinin resistance. The contribution of several K13 mutations to artemisinin resistance is investigated in different genetic backgrounds and confirms the lack of a barrier for the potential emergence of artemisinin resistance in African parasites. These findings are of prime importance in the context of public health perspective on managing the risk of resistance appearing in Africa.

  Evaluation Summary:

  Mosquito saliva can enhance transmission of arboviruses. Here, authors demonstrated that the anti-immune non-coding RNA from Dengue virus, known as the subgenomic flavivirus RNA (sfRNA), is secreted into mosquito saliva within the extracellular vesicles and can facilitate infection of the acceptor human cells when delivered together with infectious virus in mosquito saliva. The study potentially expands our understanding of flavivirus transmission.
