Understand the composition of a granuloma: Granulomas are organized structures formed during chronic inflammation, typically composed of macrophages, T cells, and sometimes giant cells.
Recognize the role of macrophages: Macrophages are a key component of granulomas, often transforming into epithelioid cells or fusing to form multinucleated giant cells.
Identify the involvement of T cells: T cells, particularly CD4+ T helper cells, are crucial in orchestrating the immune response within granulomas by releasing cytokines that activate macrophages.
Consider the presence of giant cells: Giant cells are formed by the fusion of macrophages and are commonly found in granulomas, contributing to the structure and function of the granuloma.
Evaluate the role of neutrophils: Neutrophils are typically involved in acute inflammation and are less likely to be present in granulomas, which are associated with chronic inflammation.
