    Some people experience joint pain as an inflammatory reaction to nightshades like tomatoes and peppers. Understanding the immune pathway behind that reaction — and what separates a reactive response from a tolerant one — points toward some practical places to intervene. The Immune Pathway Behind Nightshade Sensitivity Nightshade proteins are transported across intestinal microfold cells,…

    Hong et al. (2016) investigated the mechanisms behind how particulate matter, which contains chemicals such as polycyclic aromatic hydrocarbons (PAHs), causes rhinitis. This was an in vitro experiment, but they found that in cells exposed to particulate matter, reactive oxygen species were increased, while superoxide dismutase, catalase, and glutathioneperoxidase were decreased. When the cells were…
