INTRO: Conventional wisdom has held for some time that children who grow up in environments rich with biodiversity — farms, homes with pets, rural settings in general — are less likely to have allergies. The thing nobody has ever completely understood is why?
Yale researchers have now found an answer. It turns out that exposure to diverse microbes and proteins early in life creates broad immune memory and a specific antibody that helps block allergic reactions later in life. Rather than overreacting to harmless allergens (ragweed, cats, peanuts, etc.), researchers say, an experienced immune system responds in a balanced way.
The findings may inform better strategies for allergy prevention, encouraging early exposure to natural environments and new therapies that boost protective immune responses rather than just suppressing symptoms.
The all-Yale study is published in the journal Nature.... (MORE - details, no ads)
