Task Spaceflight-Induced Immune System Dysregulation and Microgravity-Associated Alterations in Microbial Virulence – Infectious Disease Risk for Astronauts

Short Title: Host Pathogen – Immune Response
Responsible HRP Element: Human Health Countermeasures

Funding Status: Active - Currently funded and in progress
Procurement Mechanism(s):

Specific Aim 1:  Profile the synergistic relationship between spaceflight analogue-altered bacterial virulence characteristics and spaceflight analogue-altered immune cell function. Alterations in immune cell responses will be evaluated when human primary immune cells are challenged with pathogens in normal and spaceflight analogue growth conditions. 


Specific Aim 2:  Profile antimicrobial efficacy for astronauts participating in spaceflight via challenge with spaceflight analogue cultured bacterial pathogens. Primary immune cells from astronauts will be profiled before, during, and post-flight to identify alterations in host response to pathogens in normal and spaceflight analogue conditions.
