T regulatory cells in childhood asthma

Asthma is a chronic disease of the airways, most commonly driven by immuno-inflammatory responses to ubiquitous airborne antigens.

Viral infections and atopy in asthma pathogenesis: New rationales for asthma prevention and treatment

Prospective birth cohort studies tracking asthma initiation and consolidation in community cohorts have identified viral infections occurring against a...

Time spent outdoors through childhood and adolescence - assessed by 25-hydroxyvitamin D concentration - and risk of myopia at 20 years

To investigate the relationship between time spent outdoors, at particular ages in childhood and adolescence, and myopia status in young adulthood using serum 25-hydroxyvitamin D [25(OH)D] concentration as a biomarker of time spent outdoors. Participants of the Raine Study Generation 2 cohort had 25(OH)D concentrations measured at the 6-, 14-, 17- and 20-year follow-ups. Participants underwent cycloplegic autorefraction at age 20 years, and myopia was defined as a mean spherical equivalent -0.50 dioptres or more myopic. Logistic regression was used to analyse the association between risk of myopia at age 20 years and age-specific 25(OH)D concentrations. Linear mixed-effects models were used to analyse trajectory of 25(OH)D concentrations from 6 to 20 years.

IgE and IgG binding patterns and T-cell recognition of fel d 1 and Non-Fel d 1 cat allergens

To compare IgE and IgG antibody binding and T-cell recognition of the major cat allergen Fel d 1 with other cat proteins with known IgE binding properties.

The contributions of solar ultraviolet radiation exposure and other determinants to serum 25-hydroxyvitamin D concentrations in Australian adults

The Quantitative Assessment of Solar UV [ultraviolet] Exposure for Vitamin D Synthesis in Australian Adults (AusD) Study aimed to better define the...

Environmental Factors in Children's Asthma and Respiratory Effects

Childhood asthma is a condition characterized by airflow obstruction that varies in time spontaneously, in response to various environmental stimuli...

The role of virus defence in childhood asthma

The overarching aim of this project is to understand how plasmacytoid dendritic cells function in children with asthma and how genes and environmental stimuli influence these cells.

Randomised controlled trial analysing supplementation with 250 versus 500 units of vitamin D3,

The rate of non-compliance with vitamin D supplementation is as high as 45%. This is why randomised controlled trials are needed to analyse the response...

Analytical bias in the measurement of plasma 25-hydroxyvitamin D concentrations in infants

To our knowledge, this is the first study to show that the reported 25(OH)D concentration may be influenced by both age and assay type
