NRG-1β also induced production and secretion of cytokines (interleukin-1α and interferon-γ) and pro-reparative factors (angiopoietin-2, brain-derived neurotrophic factor, and crypto-1), suggesting a role in cardiac repair through the activation of paracrine signaling.
Interferon-gamma expression in jejunal biopsies in experimental human cryptosporidiosis correlates with prior sensitization and control of oocyst excretion.
The production of interferon-gamma in CCE-stimulated PBMC from both immunocompetent and HIV-positive subjects with cryptosporidiosis and the lack of interferon-gamma in CCE-stimulated PBMC from HIV-positive subjects without cryptosporidiosis indicate that C. parvum mainly induces a Th1 response.
