Nasal antibody spray shields mice from pollen-triggered allergies and asthma

Intranasal delivery of a monoclonal IgG1 antibody targeting mugwort pollen protected mice from allergic rhinitis and asthma symptoms, without lowering systemic IgE levels. This localized, non-invasive approach dampened Th2 inflammation and preserved healthy airway tissue in sensitized mice.

Monoclonal antibody delivered through the nose blocks hay fever in mice

Approximately 40% of the European population are allergic to pollen, and their symptoms cause an estimated loss of 100 million school- and workdays every year.

UCLA researchers discover new way to prevent immunotherapy-induced type 1 diabetes

A team of researchers at the UCLA Health Jonsson Comprehensive Cancer Center has identified a potential new strategy to prevent, and even reverse, immune checkpoint inhibitor–induced type 1 diabetes, a rare but life-threatening side effect of cancer immunotherapy, using an existing class of autoimmune drugs.

Early exposure to plastics raises young children’s asthma risk

A large international study found that early-life exposure to phthalates, common chemicals in plastics, is modestly associated with increased risks of asthma, wheeze, and rhinitis in children under five. No consistent associations were found for bisphenols, and effects were generally small.

Mature dendritic cell vesicles enhance influenza vaccine effectiveness

Influenza hemagglutinin subunit vaccines are more effective and offer better cross protection against various influenza virus challenges when combined with a mucosal adjuvant that enhances the body's immune response, according to a study by researchers in the Institute for Biomedical Sciences at Georgia State University.

Is lactose intolerance secretly stealing your restful sleep?

Researchers surveyed over 1,000 university students and found that lactose intolerance, especially when accompanied by gastrointestinal symptoms, is linked to more frequent nightmares and poor sleep. Only a small minority reported that food affected their dreams, highlighting a specific risk for those with food sensitivities.

Fire smoke exposure found to alter immune system at the cellular level

Exposure to fire smoke-which can be composed of particulate matter, gases, materials from buildings such as perfluoroalkyl and polyfluoroalkyl substances (PFAS), toxic metals, and carcinogenic compounds-may alter the immune system on a cellular level, according to a new study led by researchers at Harvard T.H. Chan School of Public Health.

Inflammatory cells may persist despite biologic therapy in severe asthma

Biological drugs have improved the lives of many people with severe asthma. However, a new study from Karolinska Institutet in Sweden shows that some immune cells with high inflammatory potential are not completely eradicated after treatment.

Missing gut bacteria in US babies triples allergy and eczema risk

US infants lacking Bifidobacterium in their gut microbiome face significant changes in microbial composition, metabolic function, and immune-related health risks. This large, nationally representative study links early-life Bifidobacterium deficits to a three-fold increase in eczema, allergy, or asthma by age two.

Are we ready for bugs at dinner, or is the world just not that hungry for change?

Insect-based foods face major barriers, including taste, cost, and cultural acceptance, that limit their potential to replace meat in Western diets. The review finds that plant-based alternatives remain more promising for reducing environmental impacts.
