The expression of IL-1β with an immunohistochemistry technique. Microscopic views under 200x magnification show IL-1β expression in microglia cells in the control group (a), IL-1β expression in microglia cells in the AMAN group (b), and IL-1β expression in microglia cells in the AMAN with HBO group (c). (Black arrows show colored microglia cells brown which gives a positive reaction to anti-IL-1β monoclonal antibody in the lumbar vertebral bone marrow.)
