Cytomegalovirus (CMV) is a common beta-herpes-virus that is oftentimes shed in the body
fluids of astronauts during short space shuttle (10-16 days) and longer International Space …

Numerous studies have indicated that spaceflight results in dysregulation of the human
immune system. This phenomenon has been well documented following flight, where …

Your body protects you from illness with its own security system-the immune system. This
system keeps illness at bay not only by mounting a defense against foreign organisms, but …

Space flight has many adverse effects on human physiology. Changes in multiple systems,
including the cardiovascular, musculoskeletal, neurovestibular, endocrine, and immune …

Reactivation of latent herpes viruses was measured in 23 astronauts (18 male and 5 female)
before, during, and after long-duration (up to 180 days) spaceflight onboard the international …

Herpesviruses were measured in 23 astronauts with the objective of understanding their
reactivation pattern during a long-duration space mission. The measurements consisted of …

In the next several decades, humans will explore deep space, including Mars. During long-
term space flight, astronauts will be exposed to various physical stressors. Among these …

The effect of stress on immune responses associated with manned space missions is
unknown, but concern of diminished immunity on long missions is problematic. Decreased …

Background: Immunity, latent herpesvirus reactivation, physiological stress and circadian
rhythms were assessed during six month spaceflight onboard ISS. Blood and saliva samples …

Success of long duration space missions will depend upon robust immunity. Decreased
immunity has been observed in astronauts during short duration missions, as evident by the …
