Interaction between immune factors triggers cancer-promoting chronic inflammation

A Massachusetts General Hospital (MGH) research team has identified interaction between two elements of the immune system as critical for the transformation of a protective immune response into chronic, cancer-promoting inflammation. In their report published in PNAS, the investigators demonstrate that elevated levels of the immune factor IL-33 and regulatory T cells (Tregs), which suppress the action of tumor-fighting immune […]

Interaction between two immune cell types could be key to better dengue vaccines, study shows

Researchers at Duke-NUS Medical School have demonstrated for the first time a physical interaction between two types of immune cells that plays an important role in the early fight against dengue virus infection. Dengue virus is widespread in the tropics and is transmitted by mosquitos. Dengue virus infection incidence has grown dramatically in recent years, with estimates suggesting 390 million […]

Engineered immune cells target broad range of pediatric solid tumors in mice

Immune cells engineered to attack childhood cancers were able to eradicate different types of pediatric tumors in mice, according to a new study from the Stanford University School of Medicine. The study, which will be published online Jan. 17 in Clinical Cancer Research, provides evidence that these engineered cells can target many types of pediatric solid tumors, including brain tumors. […]

Immune cells trigger OCD-like behaviour in multiple sclerosis, study finds

A class of cells that defends the body against invaders also triggers obsessive-compulsive behaviour that appears in autoimmune disorders such as multiple sclerosis (MS), a new study from the Indian Institute of Science (IISc) has found. Autoimmune disorders, in which the body’s immune system goes rogue and attacks healthy cells, are difficult to treat. MS, for example, is a debilitating […]

Doctors issue caution over missed cancer diagnoses tied to immune disorder

Physicians who specialize in a devastating and aggressive immune disorder called hemophagocytic lymphohistiocytosis (HLH) report in a new study that extra care should be taken to ensure an HLH diagnosis doesn’t obscure possible underlying cancers. Because HLH is dangerously aggressive in its progression and attack on vital organs—often causing death—doctors frequently pursue immediate treatment for the immune disorder after a […]

Scientists engineer way to prevent immune response to gene therapy in mice

Stanford University School of Medicine researchers have demonstrated that gene therapy can be effective without causing a dangerous side effect common to all gene therapy: an autoimmune reaction to the normal protein, which the patient’s immune system is encountering for the first time. The researchers showed this in a mouse model that accurately recapitulates Duchenne muscular dystrophy. One in every […]

Maternal depression may alter stress and immune markers in children

New research suggests that depression in women may affect their children’s stress and physical well-being throughout life. For the Depression & Anxiety study, researchers followed 125 children from birth to 10 years. At 10 years, mothers’ and children’s cortisol (CT) and secretory immunoglobulin (s-IgA)—markers of stress and the immune system—were measured, mother-child interaction were observed, mothers and children underwent psychiatric […]

Older melanoma patients have better response to immune checkpoint blockade therapy

Patient age correlates with response to immunotherapy in melanoma and depleting regulatory T cells in young patients may have a therapeutic potential to enhance response in younger patients, according to research from The Wistar Institute. Study results were published online in Clinical Cancer Research. Immune checkpoint blockade therapy has been recently approved for treatment of melanoma based on its ability […]
