Clinical trials involving in patients with osteoporosis have reported that activated vitamin D3 (1α,25(OH)2D3, calcitriol) can prevent falling by acting on the skeletal muscles. However, pharmacological mechanisms of 1α,25(OH)2D3 with respect to sk

IL-6 is known as a multifunctional cytokine regulating immune response and inflammation. Many studies have shown that IL-6 affects the nervous system. However, the involvement of IL-6 in the nervous system, particularly in the peripheral nervous syst

We explored the mechanism for the increase of blood IL-6 level after anti-IL-6 receptor (IL-6R) antibody injection. First, we examined whether anti-IL-6R antibody stimulates IL-6 production. Single injection of tocilizumab (anti-IL-6R antibody) in mo

1,25-Dihydroxy-22-oxavitamin D(3) (22-oxacalcitriol, OCT), is a new synthetic analogue of 1,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3), calcitriol), to be used in the treatment of secondary hyperparathyroidism. This study used receptor micro-autoradio
