摘要: Abstract We used immunohistochemical techniques to study the distribution of transforming growth factor-β 1 (TGF-β ) and infiltrating lymphocytes macrophages in human astrocytomas. Thirteen 15 grade 4 astrocytomas (glioblastomas) showed staining with anti-TGF-β antibody, predominantly proliferating endothelial complexes surrounding small medium-sized blood vessels. Brain tissue microscopically free tumor cells (n = 8) more differentiated varying (1 3; n=6) devoid proliferation did not stain . Normal brain contained only rare lymphoreticular cells. The majority studied, however, T smaller numbers B lymphocytes. infiltrates were concentrated primarily close proximity Within an individual perivascular regions for TGF-β never than occasional Perivascular frequently low high inverse relationship lymphocyte is compatible a functional between this cytokine immune effector cell response glioblastomas.
