Getting exasperated! Who is holding this up?

This caught my eye:

The researchers found that cultured human airway cells exposed to both low and high concentrations of purified spike protein showed differences in gene expression that remained even after the cells recovered from the exposure. The top genes included ones related to inflammatory response.

"Our work helps to elucidate changes occurring in patients on the genetic level, which could eventually provide insight into which treatments would work best for specific patients," said Evans.

The researchers also compared their cultured human airway cells to studies from others where cells were collected from patients with COVID-19 infection. They were able to confirm that the optimized cell culture approach reflected what occurs in patients, making it useful for future translational studies. They plan to use the new approach to better understand how long the genetic changes last and the potential long-term consequences of these changes in relation to long-haul COVID-19 cases.
