Maternal OM‐85 administration alleviates offspring allergic airway inflammation by downregulating IL‐33/ILC2 axis

Maternal OM-85 administration restrains ILC2-driven allergic airway inflammation in adult offspring by increasing offspring intestinal SCFAs to modulate ILC2 development at an early stage, demonstrating that the transgenerational effects of maternal OM-85 exposure on offspring innate immunity.
