1541-Skull Bone Marrow Lymphoid Structures in CNS
Recent research establishes that the skull bone marrow serves as a specialized site for immunosurveillance of the central nervous system. Scientists identified unique lymphoid structures within the skull that contain germinal-center-like formations, where follicular helper T cells coordinate with B cells to mount immune responses. These structures are directly connected to the brain via microscopic channels, allowing them to detect and respond to CNS-derived antigens and even brain tumors. Crucially, this local immune activity can occur independently of traditional secondary lymphoid organs…
