New Tfr cell model uncovers molecular switches that restrain antibody responses

For the immune system to effectively combat pathogens, antibody responses must be precisely controlled. So-called follicular regulatory T cells (Tfr cells) play a key role in this process by limiting excessive immune responses and helping to maintain immune tolerance. Researchers

New therapeutic target for cancer identified by revealing how cancer 'hijacks' blueprint f

Anti-angiogenic therapies targeting VEGF have been widely used in cancer treatment, yet their long-term efficacy remains limited. Tumor vascular endothelial cells (TECs) exhibit high adaptive plasticity, enabling them to resist treatment and sustain tumor growth, but the molecula

Antibiotics reverse damage caused to blood stem cells by chronic Salmonella, study suggest

A new study from Ben-Gurion University of the Negev (BGU) has revealed that long-term Salmonella infections severely damage blood stem cells—the essential factory cells in bone marrow that produce all the body's blood and immune cells. However, the research, published in Cell Rep

Newfound biomarkers may someday help clinicians better detect—and possibly cure—Lyme disea

Lyme disease can be easiest to treat in its earliest stages, but current tests often miss infections during that critical window and cannot tell whether bacteria are still present or were cleared years ago. New research led by Tufts University School of Medicine suggests that a g

Repurposed epilepsy drug could be used to boost vaccine protection among elderly

A drug commonly used to treat epilepsy could be repurposed to significantly boost the response to vaccines in humans, helping protect those for whom the vaccine is less effective, such as older adults or immunocompromised people. A Cambridge-led team showed that the drug more tha

Acute respiratory distress syndrome patients improve with experimental monoclonal antibody

Doctors have few options for patients who develop a life-threatening lung condition called acute respiratory distress syndrome, or ARDS. A frequent cause of death during the COVID-19 pandemic, ARDS occurs when an inflammatory cascade triggered by infection or injury leaks fluid i
