The pleiotropic role of vitamin A in regulating mucosal immunity
The effect of vitamin A on mucosal immunity has never been subjected to extensive studies until recently. We started to work in this area in
the early 1970s when we observed that children with protein-calorie malnutrition (PCM) often had defective mucosal immunity, judging from
the incidence of respiratory tract infections and diarrhea. We reported that these children had depressed secretory IgA (sIgA) levels in their
nasal wash fluids. The IgA level in specimens collected from those superimposed with some degrees ...
The Association of Vitamin D Status with
Dyslipidaemia and Biomarkers of Endothelial Cell Activation in Older Australians
Background/Aims: Vitamin D has been investigated for many non-skeletal effects. The objective of this study was to determine whether circulating lipids, systemic inflammation, and biomarkers of endothelial cell activation varied with the vitamin D status of older Australians. Methods:
One hundred and one participants were proportionately and randomly sampled across tertiles of 25 hydroxy vitamin D (25(OH)D) from a larger cohort of free living older adults (T1 median ...
