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 volume, 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...

SARS-CoV-2 receptor ACE2 and TMPRSS2 are primarily expressed in bronch... The EMBO Journal, 2020
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...

As described in their recent Cell study, Hoffmann et al. identified the serine protease TMPRSS2 as a critical factor in the priming of the SARS-CoV-2 spike protein with its receptor ACE2, and demonstrated that a clinically proven protease inhibitor, camostat mesylate, is able to interfere with SARS-CoV-2 infection of lung cells. Featured Products: SARS-CoV / SARS-CoV-2 (COVID-19) spike antibody [1A9] (GTX632604) SARS-CoV / SARS-CoV-2 (COV...

TBC1D9 regulates TBK1 activation through Ca2+ signaling in selective a... Nature Communications , 11
Abstract Invading microbial pathogens can be eliminated selectively by xenophagy. Ubiquitin-mediated autophagy receptors are phosphorylated by TANK-binding kinase 1 (TBK1) and recruited to ubiquitinated bacteria to facilitate autophagosome formation during xenophagy, but the molecular mechanism underlying TBK1 activation in response to microbial infection is not clear. Here, we show that bacterial infection increases Ca2+ levels to activate TBK1 for xenophagy via the Ca2+-binding protein TBC1 domain family member 9 (TBC1D9). Mechanisticall...
