This may lead to issues with Th1 T-cells. ‘Although there is a lot work before us, our results suggest that problems with the Th1 subset could contribute to the Th1/Th2 T-cell balance. This idea has been around for quite a while now, but it is very satisfying to uncover new evidence for this using our genetic and practical approach,’ states Dr Jones ‘Most people with asthma or eczema are atopic – signifying they have a genetic tendency for the disorders,’ says Professor Tony Cunningham, Westmead Millennium Institute Director. ‘So this is an essential step forward in this field of genetic study.’ Related StoriesInternational research study examines effectiveness of tried and tested medications for different diseasesNew study shows siblings of kids with food allergy symptoms have sensitivity, but not true allergyMajority of individuals not allergic to intravenous penicillins, say ACAAI allergists ‘While in its early stages the research has the potential to guide the development of new medicines and topical therapies for the treatment of allergy symptoms like asthma and eczma.’ * The Institute of Allergy and Immunology is at the Westmead Millennium Institute.The conclusions of the studies, however, are inconsistent. One survey shows that mammograms have reduced the quantity of cancer deaths by 10 per cent, while another claims just as much as 36 per cent.
