Childhood infections are pushing a child to asthma, the study found

If the newborn face with a viral infection, a part of his immune system will suffer and increase the risk of developing asthma in the future. With such a warning was American experts who have studied in mice, reports BBC.

Experiment showed that infection of respiratory syncytial virus immune cells deprive ability to inhibit inflammation in the airways. This finding may give new preventive therapy, the researchers hope.

Breathing problems in asthmatics caused by narrowing of the airways due to inflammation and mucus production. This occurs when the road gets a stimulus. Previously, scientists have said about the connection recurring viral infection and increased risk of asthma.

Swedish experts have shown that 39% of children who end up in hospital with an infection, had asthma at the age of 18. Among children without infection rate was 9%. However, as it is the virus affects the body, until recently, scientists could not figure out.

In the latest research staff of the University of Pittsburgh School of Medicine, just gave an answer to this question by referring to the study of immunity. External stimuli (dust, allergens) cause maladaptive inflammatory response in asthmatics.

A virus disrupts the regulatory T cells designed to remove inflammation, completely depriving them of the ability. Rather, these cells are vulnerable as a child. Therefore, childhood infections can produce long lasting effect.
