But new research asks the question: What if immune cells could be turned back into good guys, and actually help save tissue damaged by autoimmune disease? Lupus is complicated because it wields the body’s own defenses against itself, generating a continuous immune misfire. Read the rest…
Vertex Pharmaceuticals will buy Alpine Immune Sciences, a maker of protein-based medicines that harness the immune system, for $4.9 billion, the companies announced Wednesday. It is the largest acquisition in Vertex’s history.
As elite hunters of the immune system, T cells are constantly prowling our bodies for diseased cells to attack. New research shows that some cancer cells can fire a long nanotube projection into the T cell that, like a vampire’s fang, sucks energy-creating mitochondria from the immune cell, turning the predator into prey.
The study , published Wednesday in Nature, underscores the importance of never lighting up that first cigarette, based on its conclusion that smoking has much longer harmful effects on immune responses than previously understood. Read the rest…
Researchers studying the ways these systems change with age refer to them collectively as “immunosenescence,” or, more poetically, the “ twilight of immunity. ” But even as scientific understanding of the phenomenon has grown over the past decade, the forces driving it remain murky.
Moderna announced Monday that, in a Phase 3 clinical trial, its combination Covid-19 and influenza vaccine generated stronger immune responses in older adults than individual vaccines that target those viruses.
The ads, which tell parents to contact their general practitioners if they’ve missed getting their kids immunized, are designed to capture parents’ desires to keep kids safe. Read the rest…
And while the meeting took place two days after a report that the department had tapped vaccine critic David Geier to conduct a study looking for a link between immunizations and autism, the Louisiana senator said that issue did not come up. Read the rest…
New research published Thursday in Science has identified proteins present in the blood of people with long Covid that could point the way to a much-needed diagnostic test and possibly to future therapeutic targets.
The evidence presented to the WHO team pointed to what’s sometimes called an immunity gap that was created by the pandemic. But a rapidly organized meeting Thursday between the World Health Organization and health officials in China assuaged much of that concern.
Immune checkpoint inhibitors, drugs that can help make the immune system recognize and destroy cancer more aggressively, are one of the most important medicines in cancer treatment today.
This “summer of discovery,” as McKenna called it, brought him back to the immune system. McKenna discussed possibilities with his teenagers and Prometheus’ chief scientific officer.
That’s the premise behind Normunity, which launched Tuesday with $65 million from investors to develop a suite of drugs that it dubs “immune normalizers” to help restore the natural ability of the immune system’s T cells to infiltrate and destroy tumors.
The Food and Drug Administration on Friday authorized a new antibody to protect immunocompromised individuals against Covid-19. The drug, known as Pemgarda and marketed by the biotech Invivyd, is the first such drug to become available since the agency pulled AstraZeneca’s Evusheld off the market in January 2023.
Prior research has shown that people with obesity have deficiencies in their “natural killer” cells, or NK cells — immune cells that help in combating cancer. A new small study suggests they may also be useful in fighting cancer.
Today, we see insulin-producing cells survive in a human body without triggering an immune rejection, and have some big news from CMS. Hope those of you who were in San Francisco for J.P. Morgan are resting, recovering, and not coping with any quad-emic strains. Read the rest…
LONDON — In this case, it was neither the chicken nor the egg that came first. Rather, it started with some specially engineered cells in a lab. The chicken cells had had their genomes edited, not to correct a faulty mutation, but in an effort to blunt the bird flu virus.
Alison Buttenheim was floored by a sign she saw in her doctor’s office when she went to get the first jab of the two-dose shingles vaccine to protect her against painful flare-ups of varicella zoster. “Medicare patients cannot receive Tdap or zoster vaccines here. They need to obtain [them] at their pharmacy.
This time around, we note that Immuneering hired Igor Matushansky as chief medical officer. Don’t be shy. Everyone wants to know who is coming and going. And here is our regular feature in which we highlight a different person each week.
After dropping its neuroscience program earlier this year, the clinical-stage oncology company is doubling down on a candidate targeting the MAPK pathway.
Pfizer and BioNTech said Friday that their combined mRNA vaccine candidate against influenza and Covid-19 showed a lower immune response against one type of influenza, influenza B, in a Phase 3 trial, a setback for the vaccine. ” Continue to STAT+ to read the full story…
Alison Sbrana was in the belly of an opera when her life changed. Down in the pit, surrounded by fellow orchestra members, she’d been straining to play her flute for half the show. As performers overhead enveloped the audience in arias, Sbrana felt like the Hulk was pulling on the tendons in the right side of her neck.
This happens to people whose immune systems are compromised, whether through disease or treatment, leaving them vulnerable to infections that last weeks, months, or, in one known case, a year.
Tolerance is the holy grail in calming autoimmune disease, a truce in the immune system’s faulty battle against the body’s own fabric. In type 1 diabetes, immune fighters attack beta cells in the pancreas that produce insulin, the hormone that controls glucose levels in the blood.
There’s symptom management, hopeful periods of remission often followed by relapses, but rarely a lasting fix for the way their immune system attacks healthy cells. If the immune system is an army, then those with conditions like lupus, multiple sclerosis, or rheumatoid arthritis are often fighting a never-ending war of friendly fire.
Rheumatology — the study of immune-system-driven diseases of the bones, joints, muscles, and in-betweens — has inherited plenty of hand-me-downs from cancer research. For example, there are ways of squelching an immune system in order to shrink certain kinds of cancerous tumors.
Companies that are developing new medicines for autoimmune conditions, as well as other immune system disorders, have brought in more money and closed more deals so far this year than most other areas, including the cardiometabolic field, data from investment bank Oppenheimer show.
Biogen is joining the industry’s fervor over immune and inflammatory disease drug development with a new acquisition. HI-Bio, which is based in San Francisco, is developing therapies for immune-mediated diseases like primary membranous nephropathy and IgA nephropathy, both of which impact kidney function. The Cambridge, Mass.,
New research shows that certain bacteria can alter antibodies so much that they’re unrecognizable to the body’s defenses — potentially leading to immune friendly fire. The bacteria, called Akkermansia muciniphila, can strip the sugar coating from IgA antibodies, immune proteins abundant in the gut.
Supreme Court rejected a controversial bankruptcy deal in which the owners of Purdue Pharma sought to contribute up to $6 billion in exchange for immunity from further lawsuits. The immunity had been a huge sticking point and prevented the settlement, which was first approved by a bankruptcy judge three years ago, from being finalized.
The Food and Drug Administration on Monday approved a Pfizer vaccine that aims to protect newborns against RSV by vaccinating pregnant people in the latter part of pregnancy. The vaccine, Abrysvo, has also been approved for use in adults 60 and older to protect them against respiratory syncytial virus. Read the rest…
Dupixent is already a blockbuster therapy for a range of immune-mediated diseases, but the Food and Drug Administration’s approval of the drug for chronic obstructive pulmonary disease greatly expands its reach — and could give it an edge over rival treatments in development. There are 300,000 such people in the U.S.,
Many of the effects of climate change play out at a very large scale: Heatwaves that grip entire continents. Flooding that submerges vast swaths of island nations and continental coastal areas. Other effects are far less visible because they’re taking place inside people’s bodies. That doesn’t make them any less dangerous.
The rationale for that urgency is this: An unexplained H5 infection raises the possibility of person-to-person spread of a flu virus that has never before circulated in humans, and to which people would not have immunity. And this with a dangerous flu virus that scientists have long feared could someday trigger a pandemic.
When tumors like melanoma form, the immune system mobilizes for war. White blood cells called lymphocytes rush to assault the tumor — but cancer has ways of disabling the immune system. But those immune cells still have the potential to kill cancer cells. It’s called TIL, or tumor infiltrating lymphocyte therapy.
This is precisely because vaccination requirements ensure that virtually every child’s immune system has been prepared to recognize and resist these diseases. Troubling stories about outbreaks of previously eradicated diseases like measles notwithstanding, most schools are free of vaccine-preventable diseases. Read the rest…
They should also be paying attention to adults as a new, first-of-its-kind report quantifying the economic impact of adult immunizations makes clear. The number of children who received their routine vaccinations declined during the pandemic, so public health officials have been focusing on getting kids back up to date.
However, federal officials watered down one of the auditing policies by giving insurers seven years of immunity from having the samples of their diagnosis coding errors extrapolated to their broader Medicare Advantage membership. Continue to STAT+ to read the full story…
It’s still not clear why so many positions were left unfilled on the Advisory Committee on Immunization Practices. STAT reported on the vacancies , which had flummoxed public health experts in the country, last week. Read the rest…
Early hypotheses as to what was driving the heart inflammation, called myocarditis , included an allergic response to the vaccine, vaccine-induced antibodies, or an autoimmune response in which the immune system attacks the body’s own healthy tissue by mistake.
