To quantify IL-1β release in response to Salmonella infection in THP-1-derived macrophages in a time-course experiment, human THP-1 macrophages were infected with Salmonella Typhimurium for 0, 10, 30 and 60 minutes and IL-1β release to cell culture medium was measured by ELISA-based quantitation. Here, IL1B is linked to Salmonella Infections.
