COVID-19, the novel coronavirus disease caused by SARS-CoV-2 and outbroken at the end of 2019 in Wuhan, China, becomes a worldwide pandemic. SARS-CoV-2 belongs to the betacoronavirus genus and has 79.5% identity to SARS-CoV. SARS-CoV-2 uses angiotensin-converting enzyme 2 (ACE2) as its host entry receptor.

Researchers led by Kyoto University have reconstituted the human ‘segmentation clock’ — a key focus of embryonic development research — using induced pluripotent stem cells, iPSCs.

No vaccines exist that protect people against infections by coronaviruses, including SARS-CoV-2, which causes COVID-19, or the ones that cause SARS and MERS. As COVID-19 continues to wreak havoc, many labs around the world have developed a laser-like focus on understanding the virus and finding the best strategy for stopping it.

This week in mBio, a journal of the American Society of Microbiology, a team of interdisciplinary researchers describes a promising vaccine candidate against the MERS virus. Since the MERS (Middle East Respiratory Syndrome) outbreak began in 2012, more than 850 people have died, and studies suggest the virus has a case fatality rate of more than 30%.

In the new paper, the researchers suggest that the approach they took for a MERS virus vaccine may also work against SARS-CoV-2. The vaccine’s delivery method is an RNA virus called parainfluenza virus 5 (PIV5), which is believed to cause a condition known as kennel cough in dogs but appears harmless to people. The researchers added an extra gene to the virus so that infected cells would produce the S, or spike, glycoprotein known to be involved in MERS infections.

Presence and location of gray matter in the brain may indicate whether acupuncture is an effective method of treating migraine without aura, according to a study published in Frontiers in Neurology.

Presence and location of gray matter (GM) in the brain may indicate whether acupuncture is an effective method of treating migraine without aura (MwoA), according to a study published in Frontiers in Neurology.

In many countries acupuncture is used as a treatment for migraine, but there is insufficient evidence to claim it is effective for all migraineurs. According to researchers, “about 50% of patients do not achieve substantial improvement after acupuncture.” However, determining which patients may benefit from acupuncture will prevent nonresponders from undergoing time-consuming and unsuccessful treatment.

Japan has earmarked $2.2 billion of its record economic stimulus package to help its manufacturers shift production out of China as the coronavirus disrupts supply chains between the major trading partners.

The extra budget, compiled to try to offset the devastating effects of the pandemic, includes 220 billion yen ($2 billion) for companies shifting production back to Japan and 23.5 billion yen for those seeking to move production to other countries, according to details of the plan posted online.

An ongoing long-term trial suggests high levels of amyloid proteins in the brain do serve as an early sign of Alzheimer’s disease before cognitive decline becomes apparent.

A new study presenting the first data from a long-running US government trial is suggesting high levels of amyloid proteins in the brains of cognitively normal older adults can be an effective presymptomatic sign of early stage Alzheimer’s disease.

Over the last few decades, the amyloid hypothesis has guided the majority of research into an Alzheimer’s disease treatment. The idea is that a build up of toxic amyloid proteins in the brain, called plaques, is the primary degenerative driver behind the disease.

Researchers at Lund University in Sweden have succeeded in restoring mobility and sensation of touch in stroke-afflicted rats by reprogramming human skin cells to become nerve cells, which were then transplanted into the rats’ brains. The study has now been published in the research journal PNAS.

“Six months after the transplantation, we could see how the new cells had repaired the damage that a stroke had caused in the rats’ brains,” says Professor Zaal Kokaia, who together with senior professor Olle Lindvall and researcher Sara Palma-Tortosa at the Division of Neurology is behind the study.

Several previous studies from the Lund team and others have shown that it is possible to transplant nerve cells derived from human stem cells or from reprogrammed cells into brains of rats afflicted by stroke. However, it was not known whether the transplanted cells can form connections correctly in the rat brain in a way that restores normal movement and feeling.
