Functional Heterogeneity of Splenic T Lymphocyte Subpopulations I. Determination of Splenic Subpopulations by the Use of Mitogenic Probes

Autor: J. D. Waterfield, G. Möller, R. D Ekstedt

Publikováno v: Scandinavian Journal of Immunology. 6:615-623

The results reported here suggest that there exist two T-cell-mitogenic responsive populations in the spleen--one that is responsive to concanavalin A (Con A) and a second one that is responsive to Con A and phytohemagglutinin (PHA). Using an in vitr

Experimental conditions for obtaining suppressor and helper effects on the primary in vitro immune response by lymphocytes activated by polyclonal T-cell activators

Autor: L Nespoli, D Waterfield, Göran Möller, R. D. Ekstedt

Publikováno v: The Journal of Experimental Medicine

The effect of the polyclonal T-cell activators (PTA) Con A and PHA on the specific immune response to sheep red blood cells (SRC) was studied. Addition of PTA either enhanced or suppressed the anti-SRC response, and two variables were found to affect

Correlation of Lymphocyte Transformation with the In Vivo Immune Responsiveness of Rabbits

Autor: M. A. Jevitz, R. D. Ekstedt

Publikováno v: The Journal of Immunology. 106:494-505

A comparative study of in vitro induced lymphocyte transformation with cultures of peripheral blood cells from rabbits immunized to favor delayed sensitivity or antibody production was done. Cultures made at intervals during the animals' primary, sec

Study of the Interaction of Concanavalin A with Staphylococcal Teichoic Acids

Autor: W. J. Reeder, R. D. Ekstedt

Publikováno v: The Journal of Immunology. 106:334-340

The interaction of Concanavalin A with teichoic acids from S. aureus and S. epieermidis has been studied by gel diffusion and precipitation in a fluid system. It was found that Concanavalin A reacted with alpha-glucosylated but not with beta-glucosyl

Mechanism of action of suppressor cells. In vivo concanavalin-A-activated suppressor cells do not directly affect B cells

Autor: J. D. Waterfield, L Nespoli, R. D. Ekstedt, Göran Möller

Publikováno v: Scandinavian journal of immunology. 6(3)

The addition of a small proportion (10%) of in vivo concanavalin-A (Con-A)-activated spleen cells to normal spleen cell cultures suppressed the primary immune response to sheep erythrocytes (SRBC) but had no effect on the thymus-independent primary i

Enhancement of experimental tumors in mice by treatment with concanavalin A

Autor: R D, Ekstedt

Publikováno v: Journal of the National Cancer Institute. 63(4)

Weanling BALB/c mice given injections of 300 micrograms concanavalin A (Con A) prior to and at frequent intervals after challenge with Moloney murine sarcoma virus (M-MuSV), 3-methylcholanthrene (MCA), or TEPC-15 plasmacytoma cells showed an enhancem

Factors affecting the chain length of group A streptococci. II. Quantative M-anti-M relationships in the long chain test

Autor: R D, EKSTEDT, G H, STOLLERMAN

Publikováno v: The Journal of Experimental Medicine

Minute amounts of M protein were detected in culture supernates of virulent Group A streptococci by type-specific inhibition of the long chain and the bactericidal tests for anti-M antibody. The amount of M protein that was detected by the inhibition
