The flagella connector (FC) of procyclic trypanosomes is a mobile, transmembrane junction important in providing cytotactic morphogenetic information to the daughter cell. Quantitative analyses of FC positioning along the old flagellum, involving direct observations and use of the MPM2 anti-phosphoprotein monoclonal reveals a ;stop point' is reached on the(More)
A high prevalence of vitamin D insufficiency and deficiency exists worldwide, which is associated with an increased incidence and severity of a range of immune-mediated diseases. This has resulted in considerable interest in the immunodulatory functions of vitamin D. The active form of vitamin D, 1α,25-dihydroxyvitamin D3 [1,25(OH)2D3], has been shown to(More)
BACKGROUND A small population of patients with severe asthma does not respond to glucocorticoids (steroid resistant [SR]). They have high morbidity, highlighting an urgent need for strategies to enhance glucocorticoid responsiveness. OBJECTIVE We investigated the immunologic differences between steroid-sensitive (SS) and SR asthmatic patients and the(More)
Vitamin D deficiency is associated with increased incidence and severity of various immune-mediated diseases. Active vitamin D (1α,25-dihydroxyvitamin D3; 1,25(OH)2 D3) up-regulates CD4(+) T-cell expression of the purine ectonucleotidase CD39, a molecule that is associated with the generation of anti-inflammatory adenosine. Here we aimed to investigate the(More)
