These cells shut down inflammation and repair the collateral damage to cells caused after our immune system has responded to injury or illness. Current anti-inflammatory drugs used for this purpose suppress the body's whole immune system, making patients more vulnerable to infection. Clinical trials in humans are now planned.
Researchers discovered potentially far-reaching effects of a particular gut bacterium that was linked to better growth in Bangladeshi children receiving a therapeutic food designed to nurture healthy gut microbes.
Cytokines are also targeted by drugs for many diseases such as rheumatoid arthritis, COVID-19, and cancer, but until now, scientists haven’t had a comprehensive view of how different immune cells respond to different cytokines because the immune system is so complex. What makes this study significant?

Autoimmune diseases and bone health conditions are not just medical challenges – they’re personal battles that millions of people fight every day. Fortunately, advances in clinical research are providing hope for better treatments and outcomes.
By employing a mouse model of Parkinson’s disease, the researchers have illuminated a surprising revelation: it’s the border-associated macrophages (BAMs), not the microglia, that steer the neuroinflammatory response within the brain. However, identifying the precise cells presenting the antigens remained elusive.
Manguso, who’d recently graduated from college and was conducting research at the University of Copenhagen as a Fulbright scholar, moved back to the Boston area to be with his mother as she underwent treatment.

Pharmacologic intervention has the opportunity to impact disease progression in the SARS-CoV-2 / COVID-19 crisis. Finally, I describe additional research that is required to understand the biology of SARS-CoV-2 / COVID-19, and how such research (e.g.,… The views expressed here are my own.]
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.
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.
1 The study reveals a novel bioinformatic approach and tool that holds the potential to empower researchers in designing vaccines capable of inducing a stronger immuneresponse. By selecting specific segments of proteins that elicit robust immune reactions, these vaccines could offer enhanced protection against diseases.
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.
Physicians working in the early 20th century had little choice but to treat the world’s most rampant infectious disease with methods such as these. Even after microbiologists discovered the bacterium that causes the illness in 1882, it wasn’t until the 1920s that researchers were able to develop a vaccine for TB.
gget consists of a collection of modules, each enabling researchers to perform common tasks in genomics, transcriptomics, and proteomics data analysis in just one line of code without exceeding the computational capabilities of a laptop. Was there anything particularly difficult or unexpected in the process of creating gget?
Vaccines have consistently demonstrated their efficacy in protecting people from infectious diseases. This led to the eradication of smallpox and polio – two debilitating diseases that historically caused global epidemics. Adjuvants are substances added to vaccines to enhance the immuneresponse.
Monoclonal antibody drugs are popular therapeutics for a plethora of disease conditions, from cancer to autoimmune disorders. Antibodies administered as drugs are still immunogenic, meaning that they elicit an immuneresponse from the body.
functions to reset the immune system and potentially provide remission for allergic diseases? 1104 acts upstream in the inflammatory response, targeting one of the first key players: antigen-presenting cells (APCs). In allergic diseases, APCs identify and present unknown antigens to the immune system.
New researched published in the journal Immunity , T cells exhibit an unusual, yet vital behaviour in their battle against pathogens and cancer cells, involving a nuclear receptor. This receptor, referred to as retinoic acid receptor alpha (RARα), is recognised for its regulation of gene expression within the nucleus.
In a related article, discover the cutting-edge breakthroughs in T cell research that are revolutionising our understanding of the immune system and paving the way for new therapies and treatments.
Researchers have explored systems that can deliver drugs directly to tumours in hope to reduce chemotherapy side effects. 2 Previously, La-Beck’s research has shown that liposomes made of phospholipids and cholesterol, like those used in patients, doubled tumour size in mice by suppressing their immuneresponse in some tumours.
In research published in Scientific Reports , 1 investigators focused on mesenchymal stem cells (MSCs), known for their potential in treating cell defects and regulating immuneresponses. We are studying the placement of organelles within cells and how they communicate to help better treat disease,” said Coskun.
These peptides are a vital part of the immune system’s display-recognition mechanism that enables T cells to distinguish between self and non-self-antigens, recognizing intruders to initiate immuneresponses. 3 Figure 1.
Additionally, ADSCs possess immunomodulatory properties, enabling them to modulate immuneresponses and promote tissue healing. These characteristics position ADSCs as promising candidates for addressing a wide range of medical conditions, from degenerative diseases to traumatic injuries.

Leishmania research has advanced significantly during the past three decades in a few different avenues.
Combinatorial analytics approaches identify combinations of features that together are associated with the disease phenotype in patient sub-groups, capturing the non-linear effects of interactions between multiple genes. The combinatorial approach is considerably more sensitive than GWAS and requires much smaller patient populations.
Canadian biopharmaceutical company Medicago has announced that its investigational COVID-19 vaccine generated “significant antibody and cellular immuneresponses” after two doses in all subjects in an early-stage clinical trial. Based on the promising phase 1 data, the company plans to proceed with a phase 2/3 clinical trial. “We
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. The question of how the body knows when to stop itching has intrigued researchers for years. The results were both surprising and enlightening.
