Free radicals are generated through several different pathways, e.g., during mitochondrial aerobic respiration, approximately 12% of electrons may escape the electron transport chain, and an estimated 2% of the oxygen consumed by mitochondria contributes to ROS formation, primarily the superoxide radical [25]

Quercetin is known for its ability to stabilize mast cells, which diminishes the release of histamine, the compound known to cause hypersensitivity reactions during seasonal changes

In the physiology of purine signaling, the following key elements are prominent: ATP release from cells in response to the activation of the cell surface receptor, autocrine activation of P2 receptors, ATP hydrolysis and the formation of adenosine by ectonucleotidases (Bagatini et al., 2018), activation of P1 receptors, and the removal and conversion of adenosine (Junger, 2011)
