Both 25-autoimmunity and (25 (OH) D: calcifediol) and its active form, 1, 25-dihydroxyvitamin
D (1, 25 (OH) 2D: calcitriol), play critical roles in protecting humans from invasive pathogens …

Recent studies have established that dysregulation of the human immune system and the
reactivation of latent herpesviruses persists for the duration of a 6-month orbital spaceflight …
