Microglial Depletion with Clodronate Liposomes Increases Proinflammato... Mol Neurobiol., 2019

Abstract   Investigators are increasingly interested in using microglial depletion to study the role of microglia under pathologic conditions. Liposome-encapsulated clodronate is commonly used to eliminate macrophage populations because it causes functionally irreversible inhibition and apoptosis once phagocytized by macrophages. Recent studies have shown that microglia can be depleted in disease models by injecting clodronate liposomes into the brain parenchyma. However, it is unclear whether intracerebral administration of...

Human-IgG-Neutralizing Monoclonal Antibodies Block the SARS-CoV-2 Infe... Cell Reports, 2020

A team of scientists, including researchers from Active Motif China, developed recombinant antibodies targeting SARS-CoV-2 and their work was recently published in the journal Cell Reports. Several of these antibodies were strong binders to the SARS-CoV-2 Spike S1 protein and were able to effectively neutralize infectivity of the virus, suggesting that they could be further developed and used as therapeutics against COVID-19. Learn in the following article how Wan et al. identified 11 potent neutralizingantibodies against COVID-19 from 11con...

Prostaglandin F2α influences pre-ovulatory follicle characteristics an... Theriogenology, 2020

Highlights Treatment of anovular cows with a second dose of 25 mg of prostaglandin F2α increased pregnancy per AI in normothermic cows. Treatment with prostaglandin F2α had minor impacts on LH pulsatility, but increased the size and estradiol content in the pre-ovulatory follicle. Prostaglandin has a role in fertility of anovular cows that is unrelated to its luteolytic effect. In a recent

Heightened Innate Immune Responses in theRespiratory Tract of COVID-19... Cell Host & Microbe

SUMMARY The outbreaks of 2019 novel coronavirus disease (COVID-19) caused by SARS-CoV-2 infection have posed asevere threat to global public health. It is unclear how the human immune system responds to this infection.Here, we used metatranscriptomic sequencing to profile immune signatures in the bronchoalveolar lavage fluidof eight COVID-19 cases. The expression of proinflammatory genes, especially chemokines, was markedlyelevated in COVID-19 cases compared to community-acquired pneumonia patients and healthy controls, sug-gesting that SARS...

A CRISPR-Cas9-based reporter system forsingle-cell detection of extrac... Nature Communications, 2020

Abstract Extracellular vesicles (EVs) form an endogenous transport system for intercellular transfer ofbiological cargo, including RNA, that plays a pivotal role in physiological and pathologicalprocesses. Unfortunately, whereas biological effects of EV-mediated RNA transfer areabundantly studied, regulatory pathways and mechanisms remain poorly defined due to alack of suitable readout systems. Here, we describe a highly-sensitive CRISPR-Cas9-basedreporter system that allows direct functional study of EV-mediated transfer of...

Porcine Hemagglutinating Encephalomyelitis Virus Activation of the Int... Journal of Virology, 2019

PHEV, a member of the Coronaviridae family, is a typical neurotropic virus that primarily affects the nervous system of piglets to produce typical neurological symptoms. However, the mechanism of nerve damage caused by the virus has not been fully elucidated. Actin is an important component of the cytoskeleton of eukaryotic cells and serves as the first obstacle to the entry of pathogens into host cells. Additionally, the morphological structure and function of nerve cells depend on the dynamic regulation of the actin skeleton. Therefore, exp...

The SARS-CoV-2 pandemic affecting the human respiratory system severely challenges public health and urgently demands for increasing our understanding of COVID-19 pathogenesis, especially host factors facilitating virus infection and replication. SARS-CoV-2 was reported to enter cells via binding to ACE2, followed by its priming by TMPRSS2. Here, we investigate ACE2 and TMPRSS2 expression levels and their distribution across cell types in lung tissue (twelve donors, 39,778 cells) and in cells derived fr...
