Summary: The choroid plexus (CP) is a source of trophic factors for the developing and mature brain. Insulin is produced in epithelial cells of the CP (EChPs). and its secretion is stimulated by Htr2c-mediated signaling. We modulated insulin expression in EChPs with intracerebroventricular injections of AAV5. https://cxpqlnxjxwvn7.dsiblogger.com/67920581/first-clinical-case-report-of-cytauxzoon-sp-infection-in-a-domestic-cat-in-france
