Allergen-Independent Maternal Transmission of Asthma Susceptibility

Allergen-independent maternal transmission of asthma susceptibility.

Maternal asthma is a risk factor for development of asthma in children, but mechanisms remain unclear. Offspring of asthmatic mother mice (sensitized and repeatedly exposed to OVA Ag) showed airway hyperresponsiveness and allergic pulmonary inflammation after an intentionally suboptimal OVA sensitization and exposure protocol that had little effect on normal offspring. Similar results were obta...

Role of breast milk in a mouse model of maternal transmission of asthma susceptibility.

Epidemiologic data suggest a link between nursing by asthmatic mothers and increased risk of allergy in babies. We sought to experimentally test the potential contribution of breast milk mediator(s) in a mouse model of maternal transmission of asthma risk by evaluating the effect of adoptive nursing on asthma susceptibility in the offspring. We measured airway hyperresponsiveness (AHR) and alle...

Role of Breast Milk in a Mouse Model of Maternal Transmission of Asthma Susceptibility

REVIEWER COMMENTS. It is interesting to note that the TT vaccine-specific responses in IL-10 were significant, whereas the allergen-specific responses were not. However, the clinical implication of this is not known. The authors pointed out that the types of probiotics selected and dosing regimen may be important in regard to immunologic outcomes. Some studies have shown a protective effect of ...

Model of Maternal Asthma Transmission Abrogate Allergic Susceptibility in a Murine Immunostimulatory CpG Oligonucleotides

Exposure to allergen and diesel exhaust particles potentiates secondary allergen-specific memory responses, promoting asthma susceptibility.

BACKGROUND Exposure to traffic pollution particulate matter, predominantly diesel exhaust particles (DEPs), increases the risk of asthma and asthma exacerbation; however, the underlying mechanisms remain poorly understood. OBJECTIVE We sought to examine the effect of DEP exposure on the generation and persistence of allergen-specific memory T cells in asthmatic patients and translate these fi...
