      very interesting article, there is a conclusion with insights to this underlining issue in the "read original paper" link in red. I overall think its a ear pricking issue that has yet to be solve or given the clear conclusion as to why it happens in the first place.
  • pre-flight strength: the length of this period is likely to depend on age, sex, genetic differences, and childhood exposure to pathogens.
  • These observations suggest that our immune system might be weakened by space travel.

      could it have a possible connection with the strong gravitational pull while actually going up to space? (like the continuing feeling of a steep rollercoaster drop).

  • change in gene expression of leukocytes under microgravity is triggered by ‘fluid shift’, where blood plasma is redistributed from the lower to the upper part of the body, including the lymphatic system. This causes a reduction in plasma volume by between 10% and 15% within the first few days in space. Fluid shift is known to be accompanied by large-scale physiological adaptations, apparently including altered gene expression.
