IL10 and delirium: In order to investigate the molecular mechanisms through which cell treatment with serum samples from delirium patients detrimentally affected cell proliferation, neurogenesis and apoptosis, we first measured levels of candidate cytokines (IL1β, IL2, IL4, IL6, IL8, IL10, IL12, IL13, TNF-α, IFN-γ) known to be modulated by the SARS-CoV-2 virus [11–13], in serum samples of both patients with delirium and without delirium.
