Liu et al., Science 2006
(Disease Susceptibility...) :
We report here that TLR activation of human macrophages up-regulated expression of the vitamin D receptor and the vitamin D-1-hydroxylase genes, leading to induction of the antimicrobial peptide cathelicidin and killing of intracellular Mycobacterium tuberculosis
Adams et al., J Immunol 2009
(Vitamin D Deficiency) :
In monocytes/macrophages, this occurs primarily in response to activation of TLR , that induce expression of the vitamin D receptor and localized synthesis of 1,25 ( OH ) ( 2 ) D from precursor 25-hydroxyvitamin D ( 3 ) ( 25OHD )
Wang et al., J Steroid Biochem Mol Biol 2013
(Alveolar Bone Loss...) :
Immunohistochemical staining and western blot analysis of gingival epithelia revealed that vitamin D receptor (VDR) expression was enhanced upon 25-OHD treatment, while toll-like receptor 4 (TLR4) expression was reduced
