antibodies stay in the blood for at least 8 months, study finds

published on Tuesday, May 11, 2021 at 6:02 p.m.

Antibodies neutralizing Covid remain in the blood for at least eight months after infection, according to an Italian study published on Tuesday.

This observation is valid “regardless of the severity of the disease, the age of the patients or the presence of other pathologies”, according to this study carried out by the prestigious San Raffaele Hospital in Milan in collaboration with the Higher Institute of Santé (ISS), the body advising the government on public health matters.

“The presence of antibodies, although it decreases over time, is very persistent: eight months after the diagnosis, only three patients” out of the 162 follow-ups (29 of whom died) were no longer positive for the blood test. detection of these antibodies, explained in a joint statement the San Raffaele and the ISS.

In addition, the early presence of these antibodies is “fundamental to successfully fight infection: those who fail to produce them in the first two weeks after contagion are at greater risk of developing severe forms of Covid-19”.

This study was carried out by the Viral Evolution and Transmission Unit of San Raffaele Hospital, in collaboration with researchers from the Diabetes Research Institute of the same establishment, who developed a specific test for antibodies. by using techniques already used to study the antibodies involved in the autoimmune response underlying type 1 diabetes.

Using techniques already used for the study of anti-HIV vaccines, researchers at San Raffaelle and the ISS have also developed a new method for evaluating antibodies neutralizing SARS-CoV-2.

The study, published Tuesday in Nature Communications, made it possible to “map in an almost exhaustive way the evolution over time of the antibody response to Covid-19”, estimate the ISS and the San Raffaele.

The study was carried out by following 162 SARS-CoV-2 positive patients (67% male, mean age: 63) who presented to the emergency room at San Raffaele during the first wave of the pandemic in Italy. The first blood samples were collected at the time of diagnosis in March-April 2020, the last ones at the end of November 2020.

57% suffered from a pathology other than Covid at the time of diagnosis. The most common were hypertension (44%) and diabetes (24%).

Pfizer tests pill against coronavirus – Coronavirus Vienna


The corona pill could appear this year.

A pill against the coronavirus could hit the market later this year. The Pfizer company is currently working on it, and tests on adults are already underway.

In the fight against the coronavirus, everything currently revolves around vaccination. Research into other methods to defeat the virus has long been underway. Pfizer, for example, wants to have a pill on the market by the end of the year, as the company has now revealed.

There have been reports that tests are already being carried out on adults in the United States and Belgium. It is a pill that is taken orally and one that is inserted intravenously. However, the focus is on the pill for various reasons, as it eliminates the need for an appointment at the hospital or the doctor.

After ingestion, the agent is intended to ensure that the virus cannot reproduce any further as soon as someone is infected with it. Allegedly, the pill should also work with all mutations. Further details should be available in summer, so the corona pill could be launched on the market this year.

Alzheimer’s: Four types of diseases discovered – better treatment possible – guide

Better knowledge of the course and better treatment options: this discovery could significantly improve the treatment of Alzheimer’s disease. Researchers at McGill University in Montreal have found that there are four subtypes of the disease.

This creates a new picture: instead of just one, there are several similarly common subtypes of Alzheimer’s disease. With this knowledge, it could be possible to better recognize, classify and treat typical failures and symptoms, according to the researchers led by study director Jacob Vogel in the specialist journal “Nature Medicine”.

According to the scientists, these four subtypes are reflected in the distribution of so-called tau proteins in the brain and are associated with different symptoms and prognoses. So far, the causes and neurophysiological circumstances of the disease are not sufficiently known. Apparently, the accumulation of the tau proteins in the brain cells can accelerate their breakdown.

When examining these tau proteins, the experts scanned the distribution of the tau proteins in the brain of 1612 test persons using positron emission tomography (PET). Using an algorithm, they then looked for conspicuous patterns. The surprising result: the distribution in the brains of Alzheimer’s patients did not follow the expected pattern, but four different patterns. “Alzheimer’s is more heterogeneous than expected. We have to reassess the concept of ‘typical’ Alzheimer’s disease, ”says study director Jacob Vogel.

This is how the four different types differ

– In subtype 1, the tau proteins mainly spread in the temporal lobe. It leads to severe memory problems, other brain functions are less affected. This type occurred in 33 percent of the Alzheimer’s patients examined.

– Subtype 2, on the other hand, shows tau proteins distributed throughout the cerebral cortex, but they accumulate in the right hemisphere. 18 percent are affected by this variant. They have fewer memory problems, but lose the ability to plan and implement actions.

– 30 percent of Alzheimer’s patients have subtype 3. Here’s it Processing of impressions disturbed. Those affected find it difficult to orientate themselves, have difficulty distinguishing between shapes and assessing distances.

– Subtype 4 shows tau proteins mainly in the left hemisphere. Here is the one general mental degradation strongly pronounced, language problems also occur. 19 percent of the cases are due to this type.

Art mission for kids: the best picture will adorn the Jupiter rocket


ESA wants to inspire the younger generations with a new campaign for space. Children up to the age of twelve can submit their works of art to the space agency. The winning picture will then adorn an Ariane 5 rocket on its launch to Jupiter next year.

ESA makes children part of an exciting space mission

It is a good custom that each space mission is accompanied by its own illustration, which can often be found on the rocket. In this regard, the European Space Agency ESA is now calling on children up to the age of twelve to become part of the upcoming “JUpiter ICy moons Explorer” mission, or JUICE for short, with creative works. “The Juice Up Your Rocket! Art competition calls on all children ages 3 to 12 to help ESA create an illustration to decorate the giant Ariane 5 rocket that will take the spacecraft on its long journey to the planet Jupiter will start. ”
ESA calls on kids: Juice Up Your Rocket!
As the agency writes on the JUICE art competition website, the little artists should be inspired by the mission and the planet Jupiter and its large moons. A jury of experts, “led by Paxi”, the official ESA children’s mascot, will then select the “most inspiring work of art”. In the next step, a sticker measuring around 4 x 3.4 m will be made from the winning illustration, which will then adorn the payload fairing – that is, the “nose” of the Ariane 5 rocket – at the planned launch in 2022. The image is also used in connection with all other parts of the JUICE campaign.

Not only the winner wins

But there are also rewards for all other participants. ESA is putting together a gift package for the twelve best works of art – including a Lego model of the JUICE space probe on a scale of 1:60. In addition, these images will be immortalized in a JUICE calendar for 2022, which will be freely available online. Last but not least, all participants will receive a certificate of participation and the contributions will be available in a separate picture gallery on the ESA Kids website. All other conditions of participation for the Juice Up Your Rocket! You can find the art competition in the guidelines PDF.
