An anonymous San Diego resident has become a fascinating example of how the human immune system fights SARS-CoV-2.
LA JOLLA, CA—Getting sick with a common cold doesn’t make you immune to COVID-19, but a COVID-19 infection might, at least temporarily, boost the number of antibodies you have against common cold-causing coronaviruses and the SARS-CoV-1 and MERS-CoV viruses, all of which are closely related.
million ($2 million) to develop its artificial intelligence-based platform for discovering therapeutic antibodies. The Cardiff, Wales startup is combining machine learning and phage display techniques to model antibody-antigen binding and says it can cut the time it takes to develop a drug candidate.
Scientists now use cutting-edge techniques, including biological therapies that target specific immune system components and precision medicine approaches that personalize treatment plans based on a patient’s genetic profile.
Boehringer Ingelheim’s latecomer antibody therapy for COVID-19 has been side-lined, as the company focuses its attention on its thrombolytic drug alteplase, heading into a phase 3 programme later this year. The hope was that an inhaled antibody would reach higher levels in the lung, where it is most needed, than systemic antibodies.
Scientists now use cutting-edge techniques, including biological therapies that target specific immune system components and precision medicine approaches that personalize treatment plans based on a patient’s genetic profile.
As the world continues to learn how to live with Covid-19 in the long run, scientists are testing ways to quickly tell people how well-protected they are against the virus, and whether they need another booster.
Findings point the way to developing a broad-spectrum flu drug Credit: Yanan Dai Researchers have identified two antibodies that protect mice against lethal infections of influenza B virus, report scientists at Washington University School of Medicine in St. Together with an antibody that targets the other […].
LA JOLLA, CA—Scientists at La Jolla Institute for Immunology (LJI) have published the first analysis of how four types of COVID-19 vaccines prepare the body to fight SARS-CoV-2.
” The antibody, which is partnered with Eisai, made second-quarter sales of $1.6 As Vounatsos was updating investors and analysts on progress, a group of scientists at Beth Israel Deaconess Medical Center (BIDMC) published a letter in the Journal of the American Medical Association (JAMA) taking issue with the revised label for Aduhelm.
A study conducted by a consortium of Brazilian researchers has demonstrated that a hyperimmune serum consisting of purified antibody fragments produced in horses may be an efficient approach to combat covid-19. The neutralizing activity of the sera developed by the scientists has been proved to be […].
Centuries later, scientists now know this to be a circadian rhythm, a 24-hour cycle that readjusts in response to environmental cues such as sunlight. Studies show that wounds heal faster during the day, and patients over 65 produce more antibodies if they get a flu shot in the morning. Read the rest…
The patent battle between Amgen and Sanofi over their cholesterol-lowering antibodies has divided big pharma in the past months. Both drugs are monoclonal antibodies that inhibit the protein PCSK9. To an extent, the challenge here lies in the nature of antibodies, says Contreras. Amgen’s Repatha was greenlit a month later.
A second study by scientists in the United States, published alongside the Imperial-led one in the journal Nature, estimated that lockdowns in China, South Korea, Italy, Iran, France and the United States had prevented or delayed around 530 million COVID-19 cases.
Researchers have found that a natural molecule can effectively block the binding of a subset of human antibodies to SARS-CoV-2. The discovery may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus.
WHAT: A booster dose of the mRNA-1273 COVID-19 vaccine given to rhesus macaques about six months after their primary vaccine series significantly increased levels of neutralizing antibodies against all known SARS-CoV-2 variants of concern, according to a new study from National Institutes of Health scientists and colleagues.

Credit: Rayne Zaayman-Gallant/EMBL The ability of SARS-CoV-2 to infect cells depends on interactions between the viral spike protein and the human cell surface protein ACE2. To enable the virus to hook onto the cell surface, the spike protein binds ACE2 using three finger-like protrusions, called the receptor binding domains (RBDs).
