Germinal centre protein HGAL promotes lymphoid hyperplasia and amyloidosis via BCR-mediated Syk activation

The human germinal centre-associated lymphoma gene is expressed in germinal centre B-lymphocytes; however, its function is unknown. Here the authors show that human germinal centre-associated lymphoma activates Syk kinase, leading to lymphoid hyperplasia and systemic reactive amyloid A amyloidosis in transgenic mice.
