Study examining blocking sars-cov-2 delta variant (b.1.617.2) spike protein receptor-binding. Space travel significantly compromises immune function through impaired T-cell activity, reduced NK cell function, and inflammatory cytokine dysregulation. Latent viruses frequently reactivate, and wound healing is delayed. These findings raise concerns about infection risk and vaccine effectiveness during long missions.
Study examining blocking sars-cov-2 delta variant (b.1.617.2) spike protein receptor-binding. Spaceflight induced significant immune system dysregulation. T-cell function was impaired with reduced proliferation capacity. Natural killer cell activity decreased substantially. Cytokine profiles shifted toward pro-inflammatory states. Latent viral reactivation occurred in 60% of crew members. Wound healing processes were delayed. Vaccine efficacy may be compromised in space environments.
