A new study analyzing the immune response to COVID-19 in a Catalan cohort of health workers sheds light on an important question: does it matter whether a person was first infected or first vaccinated?
A research team at the Nano Life Science Institute (WPI-NanoLSI) and the Faculty of Medicine at Kanazawa University has developed a new class of engineered extracellular vesicles (EVs) capable of inducing antigen-specific regulatory T cells (Tregs), th…
A recently approved injectable eczema drug provides quick itch relief to patients with the maddening skin disease, a new study says.
When killer T cells of our immune system divide, they normally undergo asymmetric cell division (ACD): Each daughter cell inherits different cellular components, which drive the cells toward divergent fates—one cell becomes a short-lived fighter called…
Feeding babies peanut-containing foods as early as possible can help prevent peanut allergy, but a new study published in JAMA Network Open found that parents need more support to get it right. Interviews with parents revealed widespread confusion abou…
Alveolar macrophages are immune cells that live in the tiny air sacs of the lungs. Under normal conditions, these cells act as guardians, keeping the lungs healthy, supporting breathing, and preventing unnecessary immune responses.
As people age, their immune system function declines. T cell populations become smaller and can’t react to pathogens as quickly, making people more susceptible to a variety of infections.
mRNA vaccines, such as those used against COVID-19, are effective at generating antibody responses. These antibodies are produced through specialized immune structures called germinal centers, but until now it was not fully understood how mRNA vaccines…
The process of aging is associated with a decline in immune functions and persistent low-level inflammation. Now, researchers from Japan have discovered a strain of Lentilactobacillus capable of preventing and even reversing aging-related immune altera…
Antibiotics are powerful treatments that have saved countless lives over the course of decades. New findings from Scripps Research have identified a way to preserve healthy immune development even when infants need antibiotic treatment.
