News at a glance: New gene therapy, Europe ’s drought, and a black hole’s photon ring
ARCHAEOLOGY Drought exposes ‘Spanish Stonehenge’ for study Scientists are rushing to examine a 7000-year-old stone circle in central Spain that had been drowned by a reservoir for decades and was uncovered after the drought plaguing Europe lowered water levels. Nicknamed the “Spanish Stonehenge”—although 2000 years older than the U.K. stone circle—the Dolmen of Guadalperal (above) was described by archaeologists in the 1920s. The approximately 100 standing stones, up to 1.8 meters tall and arranged around an oval open space, were submerged in the Valdecañas reservoir after the construction of a ...

What We Learned About Genetic Sequencing During COVID-19 Could Revolutionize Public Health
You don’t want to be a virus in Dr. David Ho’s lab. Pretty much every day since the COVID-19 pandemic began, Ho and his team have done nothing but find ways to stress SARS-CoV-2, the virus that causes the disease. His goal: pressure the virus relentlessly enough that it mutates to survive, so drug developers can understand how the virus might respond to new treatments. As a virologist with decades of experience learning about another obstinate virus, HIV, Ho knows just how to apply that mutation-generating stress, whether by starving the virus, bathing it in antibodies that disrupt its ability to infect cells, ...

mRNA Technology Gave Us the First COVID-19 Vaccines. It Could Also Upend the Drug Industry
“No!” The doctor snapped. “Look at me!” I had been staring her in the eyes, as she had ordered, but when a doctor on my other side began jabbing me with a needle, I started to turn my head. “Don’t look at it,” the first doctor said. I obeyed. This was in early August in New Orleans, where I had signed up to be a participant in the clinical trial for the Pfizer-BioNTech COVID-19 vaccine. It was a blind study, which meant I was not supposed to know whether I had gotten the placebo or the real vaccine. I asked the doctor if I would really been able to tell by looking at the syringe. &...

The Great Vaccine Race: Inside the Unprecedented Scramble to Immunize the World Against COVID-19
The cleverest of enemies thrive on surprise attacks. Viruses—and coronaviruses in particular—know this well. Remaining hidden in animal hosts for decades, they mutate steadily, sometimes serendipitously morphing into more effective and efficient infectious agents. When a strain with just the right combination of genetic codes that spell trouble for people makes the leap from animal to human, the ambush begins. Such was the case with SARS-CoV-2, the coronavirus behind COVID-19, and the attack was mostly silent and insidious at first. Many people infected with SARS-CoV-2 remained oblivious as they served as the v...

Use of Google Trends to investigate loss ‐of‐smell‒related searches during the COVID‐19 outbreak
ConclusionThere is a strong correlation between the frequency of searches for smell ‐related information and the onset of COVID‐19 infection in Italy, Spain, UK, USA, Germany, France, Iran, and The Netherlands. We hypothesize this may relate to a previously underrecognized symptom.

Human, Nonhuman Primate, and Bat Cells Are Broadly Susceptible to Tibrovirus Particle Cell Entry
Discussion Tibroviruses are highly undercharacterized rhabdoviruses with unknown pathogenic potential. All isolated tibroviruses (BAV, BHV, CPV, SWBV, and TIBV) have only been found in biting midge vectors or in various, apparently healthy non-human mammals (Cybinski et al., 1980; Standfast et al., 1984; Cybinski and Gard, 1986; Gibbs et al., 1989). The discovery of BASV, EKV-1, and EKV-2 genomes in human sera (Grard et al., 2012; Stremlau et al., 2015) suggests that at least some tibroviruses could infect humans. Because BASV was discovered in the serum of a severely ill individual, tibroviruses should be considered pote...

Innate Lymphoid Cells: Expression of PD-1 and Other Checkpoints in Normal and Pathological Conditions
Conclusions and Future Perspectives It is now evident that NK/ILC family plays a pivotal role in the immune defenses. Recent studies in murine and human settings demonstrated that the expression of several inhibitory checkpoints, that may be detrimental in the tumor context, is not restricted to T lymphocytes, revealing an important, yet poorly appreciated, contribution of their expression on innate immune cells. Thus, in the recent years different immunotherapy approaches, based on the blockade of inhibitory NK cell receptors, have been developed in order to unleash NK cell cytotoxicity. This is particularly important in...

Surface (S) Layer Proteins of Lactobacillus acidophilus Block Virus Infection via DC-SIGN Interaction
We describe the unexpected binding of S-layer to cells devoid of DC-SIGN but also confirm that the presence of DC-SIGN was essential for S-layer’s antiviral activity. S-layer protein exerted its antiviral effect with different kinetics than mannan, a known viral inhibitor that also acts on DC-SIGN (Yu et al., 2017). Together our results suggest that inhibition of viral entry by S-layer occurs via a novel S-layer/DC-SIGN interaction. Materials and Methods Isolation of S-Layer Proteins S-layer proteins were extracted from overnight cultures of L. acidophilus ATCC 4356 cells grown in MRS medium at 37°C by usi...

The Human Upper Respiratory Tract Epithelium Is Susceptible to Flaviviruses
In this study, we exposed apically well-differentiated human NECs cultured at the ALI to the related flaviviruses ZIKV, JEV, WNV, and Usutu virus (USUV). We selected these viruses due to the recent increasing evidences of potential threat to humans (Cadar et al., 2017; Simonin et al., 2018). We show that NECs are particularly susceptible to JEV and WNV infection and to other flaviviruses included in this study. Infection with each virus led to shedding of infectious virus particles through the apical and basolateral surfaces and triggered host mechanisms at the level of inflammatory and antiviral mediators....

Group 2 Innate Lymphoid Cells Are Redundant in Experimental Renal Ischemia-Reperfusion Injury
In this study, we sought to further characterize ILC2s in the kidney, their location within this organ and determine their functional role in IRI using a loss-of-function approach. Here, we found that kidney ILC2s constitutively express IL-5 and are primarily located in close proximity to the renal vasculature, within the adventitia. Additionally, we demonstrate that a reduction, deficiency or depletion of ILC2s had minimal impact on the severity of IRI. Whilst activation of ILC2s and the associated amplification of local type 2 immunity has been previously shown to reduce the deleterious consequences of AKI, our results r...
