Journal Article
T cell-replacing factor- (TRF) induced IgG secretion in a human B blastoid cell line and demonstration of acceptors for TRF.

TL;DR: IgG-secretion was induced in a human B blastoid cell line, CESS, by the addition of partially purified T cell-derived helper factor(s) (TRF), which had been obtained from PHA-stimulated human T cells, and showed the presence of acceptors for TRF on the surface of CESS cells.
Journal Article
Induction of proliferation and Ig production in human B leukemic cells by anti-immunoglobulins and T cell factors.
TL;DR: Stimulation of B-CLL cells with anti-Ig and T helper factors could induce proliferation as well as differentiation into IgM- and IgG-producing cells but monovalent Fab' fragments were not effective.
Journal ArticleDOI
B cell growth factors and B cell differentiation factor from human T hybridomas. Two distinct kinds of B cell growth factor and their synergism in B cell proliferation.

TL;DR: The results demonstrated that IL-2, BCGF, and BCDF were different molecules and acceptors specific for the each molecule are present on the each target cell.
Journal ArticleDOI
Isolation of catecholamines in biological fluids by boric acid gel.
TL;DR: A new method is presented for the isolation of catecholamines in biological fluids using boric acid gel that offers some advantages over the previous aluminum oxide method with respect to simplicity, reproducibility, and recovery.
Journal Article
In Vitro Immune Response of Human Peripheral Lymphocytes I. The Mechanism(s) Involved in T Cell Helper Functions in the Pokeweed Mitogen-Induced Differentiation and Proliferation of B Cells
TL;DR: The kinetic studies showed that the proliferation of B cells took place in advance of the final differentiation to Ig-producing cells and that T cells or T cell product(s) had to exist at the initiation of cultures in order to give the maximum helper effect.
