B cells are critical to the development of multiple sclerosis (MS), but the mechanisms by which they contribute to the disease are poorly defined. We hypothesised that the expression of CD32b (FcγRIIb), a receptor for the Fc region of IgG with inhibitory activities in B cells, is lower on B cell subsets from people with clinically isolated syndrome (CIS) or MS. CD32b expression was highest on post-naive IgM+ B cell subsets in healthy controls. For females with MS or CIS, significantly lower CD32b expression was identified on IgM+ B cell subsets, including naive and IgMhi MZ-like B cells, when compared with control females. Lower CD32b expression on these B cell subsets was associated with detectable anti-Epstein Barr Virus viral capsid antigen IgM antibodies, and higher serum levels of B cell activating factor. To investigate the effects of lower CD32b expression, B cells were polyclonally activated in the presence of IgG immune complexes, with or without a CD32b blocking antibody, and the expression of TNF and IL-10 in B cell subsets was assessed.
The role of oestrogen in experimental atopic asthma, and guide future research on sex-related variations in atopic asthma susceptibility/intensity
Neutrophils are a type of immune cell that can trigger inflammation and may play a role in the development of MS.
Large numbers of children need emergency medical treatment each year for respiratory illnesses, particularly for wheezing and asthma.
Healthy skin is important for maintaining overall physical and cultural health and wellbeing. However, remote-living Australian Aboriginal children contend with disproportionally high rates of Streptococcus pyogenes (Strep A) infected impetigo.
Achieving healthy skin requires the prevention of infectious diseases that affect the skin. Prevention activities range from environmental health improvements to address inequities in living situations, through to community-wide treatment programs to reduce transmission and improve skin health.
Language is significant for communicating knowledge across cultures and generations and has the power to attribute meanings and alter our worldviews.
This study investigates various common medical conditions affecting Australian children aged 4–14 years and the impact of prenatal and early-life conditions on these health conditions using a large national data set with 15 years of follow-up.
Amidst growing concerns over heightened natural disaster risks, this study pioneers an inquiry into the causal impacts of cyclones on the demand for private health insurance in Australia. We amalgamate a nationally representative longitudinal dataset with historical cyclone records, employing an individual fixed effects model to assess the impacts of various exogenously determined cyclone exposure measures.
In Australia, although there have been some improvements, child oral health continues to be a major public health issue. The Australian Government introduced the means-tested Child Dental Benefits Schedule (CDBS) in 2014 to support access to dental services for children and adolescents aged 0-17 years from low-income families.
