Which tissue type forms aggregates of immune cells in mucosal sites?

In mucosal tissues, immune defense relies on small clusters called lymphatic nodules. These nodules are part of mucosa-associated lymphoid tissue (MALT) and are typically packed with B cells, often showing a germinal center when activated. They form aggregates right in the mucosal lining of areas like the gut and respiratory tract, providing localized immune responses to antigens encountered at these surfaces. This structure differs from lymph nodes, which are separate filtering organs along lymphatic vessels, from tonsils, which are a specific ring of lymphoid tissue in the pharynx, and from the thymus, which is where T cells mature. So the tissue type that forms aggregates of immune cells in mucosal sites is lymphatic nodules.
