Tests, in mice, of a drug developed by the researchers showed that regulatory T cells can be attracted to specific body parts, boosted in number, and activated to suppress immuneresponse and rebuild tissue.
Scientists have discovered a molecular defect that promotes the pathologic immuneresponse in systemic lupus erythematosus (known as lupus) and show that reversing this defect may potentially reverse the disease.
Their findings uncover detailed information that could help overcome the limitations of today's immunotherapies and identify new drug targets for a wide range of diseases, including autoimmune diseases and cancer.
The immune system can carry out many biological processes, from killing viruses to fighting cancer, thanks in large part to approximately 100 key cell-signaling proteins called cytokines, which instruct immune cells what to do. The reference, called the Immune Dictionary , appears today in Nature.
A switch of just two weeks from a traditional African diet to a Western diet causes inflammation, reduces the immuneresponse to pathogens, and activates processes associated with lifestyle diseases. This study highlights the significant impact of diet on the immune system and metabolism.
A strain of the bacterium harbored in the children's gut microbial communities possessed a previously unknown gene capable of producing and metabolizing key molecules involved in regulating many important functions ranging from appetite, immuneresponses, neuronal function, and the ability of pathogenic bacteria to produce disease.
Researchers have demonstrated that a transplant surgical procedure (called 'needle trauma') triggers a profound immuneresponse and causes the death of most grafted dopamine neurons.

By Ari Navetta October 15, 2024 Credit: Allison Colorado, Broad Communications Eric Brown is studying the links between the microbiome and disease. The Xavier Lab looks at interactions between microbes in your gut and your immune system, and diseases such as arthritis and inflammatory bowel disease (IBD).
Approximately three percent of the global population — 240 million people — experience autoantibody diseases, which occur when one’s own body attacks critical organs and tissues. Antibodies protect us by attaching to molecules on those invaders (known as antigens) and triggering our body’s natural immuneresponse to destroy them.
The first peer-reviewed study in North America examining the timing between the first and second doses of COVID-19 mRNA vaccines shows that a longer dose interval leads to a stronger immuneresponse. The study is funded by the Government of Canada through its COVID-19 Immunity Task Force (CITF).
By examining the genomes of bacteria collected from hundreds of people with persistent Salmonella infections, they discovered genetic mutations that both reduce the bacteria’s “virulence,” or ability to infect, and dampen the host’s immuneresponses, creating a kind of molecular camouflage that shields the bacteria from the immune system’s gaze.
In April 2023, we saw the first randomised data applying an individualised vaccine in combination with checkpoint inhibition for resectable melanoma, demonstrating benefit in terms of time to disease recurrence. Espen integrates clinical and research expertise as Director of Medical Affairs.

The grant will enable her to investigate the interaction of nanoparticles with the immune system and cancer, supporting the development of new drug delivery systems.
He also read everything he could about her disease, including emerging evidence that suggested that the immune system could recognize and kill Merkel cell carcinoma. His mother had a presentation of the disease that suggested her immune system was already on the job. We’re deeply grateful for that.”
Adjuvanted recombinant COVID-19 vaccine candidate triggered strong neutralizing antibody responses in all adult age groups. High immuneresponse after a single dose in patients with prior infection shows strong booster potential. For media and investors only. Issued: London UK. About the Phase 2 study. Sanofi, Empowering Life.
The molecular tools of CRISPR were borrowed and developed from the natural immuneresponse of bacteria to viruses – bacteriophages – that infect them. CRISPR may make sense for replacing a single mutant gene, like the one behind sickle cell disease, for which a CRISPR-based gene therapy was recently approved.
This interaction inhibits inflammation and immune activation, and in particular prevents macrophages from phagocytosing and destroying cancer cells. By blocking CD24 with an antibody drug, our goal is to powerfully reactivate the anti-cancer immuneresponse and drive therapeutic efficacy.
Their research centres around a remarkable immune protein called IL-31, which not only induces itching but also plays a crucial role in regulating inflammation. It’s the first time they have seen the nervous system directly tamp down an allergic response.
Researchers from the Nara Institute of Science and Technology (NAIST) have used the reverse-blastocyst complementation (rBC) method to understand the conditions required to form lungs in rat-mouse chimeric models. Chronic obstructive pulmonary disease Chronic obstructive pulmonary disease (COPD) is the third leading cause of global deaths.
Laboratory professionals in all areas of science have experienced significant changes in recent years, and 2022 was no exception. Additionally, chronic disease, cancer and neurodegenerative disorders like Alzheimer’s were top of mind last year for diagnostics and drug R&D teams alike.
These factors are converging to enable both identification of novel infectious diseases as well as microbial resistance, before these threats can impact public health, write a team from the European Society for Clinical Microbiology and Infectious Diseases in Frontiers in Science. COVID clearly caught us off guard.
Advances in disease understanding and combination strategies in haematology We now know that blood cancers are characterised by molecular and phenotypic heterogeneity. 2 It is this complexity that necessitates powerful, targeted combination therapies.
Lead Pharma has entered into a collaboration and license agreement with Roche , hoping to lead the way in the development of oral small molecules for immune-mediated diseases like rheumatoid arthritis, psoriasis and inflammatory bowel diseases. . The agreement encompasses Lead Pharma’s entire pipeline.
Last summer, we published a first signal of efficacy in humans in the LANCET Infectious Diseases for our lead broad-spectrum influenza candidate, OVX836. DGG: Resilience: In science, we can’t predict and control everything. Sometimes science “speaks” and sometimes it doesn’t.
This method was more about serendipity than science. Today, we're able to identify and target specific molecules involved in disease processes—a method that's much more like using a sniper rifle than throwing darts blindfolded. But as molecular biology has advanced, so too has our approach to finding new drugs.
Last week DNA Science covered a setback in a clinical trial of a gene therapy for Duchenne muscular dystrophy (DMD). Also recently, FDA’s Cellular, Tissue, and Gene Therapies Advisory Committe turned down a stem cell treatment for amyotrophic lateral sclerosis, aka ALS, Lou Gehrig’s disease, or motor neuron disease.
In the final chapter of my 2012 book The Forever Fix: Gene Therapy and the Boy Who Saved It , I predicted that the technology would soon expand well beyond the rare disease world. Gene therapy clearly hasn’t had a major impact on health care, offering extremely expensive treatments for a few individuals with rare diseases.
Antibody-drug conjugates (ADCs) have been a groundbreaking approach to cancer treatment with their ability to deliver cytotoxic drugs directly to diseased cells while sparing healthy tissues. 15 ISACs use small immuno-agonist molecules conjugated to the antibody to boost the immuneresponse while minimising toxicity.
