An analysis of transport, exchange, and binding of sodium and potassium in isolated amphibian follicles and denuded oocytes. | The uptake and efflux of 22Na and 42K were studied in fully grown, prophase-arrested Rana pipiens follicles and denuded oocytes. Follicles and denuded oocytes contained large stores of both cations, although only 15--30% of the total Na+ and 1--2% of the total K+ pools exchanged within the 12-h period studied. 22Na upt... | 303,645 | [

Suggested models of ecotaxopathy in lymphoreticular malignancy. A role for iron-binding proteins in the control of lymphoid cell migration. | In the present paper we apply the "ecotaxis hypothesis" to the analysis of lymphocyte distribution in Hodgkin's disease and other forms of lymphoid malignancy. The results lead us to consider the possiblity that metal-binding proteins, namely ferritin, transferrin and lactoferrin, play a role in lymphocyte ecotaxopahty... | 304,676 | [

Transfer of concanavalin A between responding lymphocytes and syngeneic stimulating cells in cell-mediated mitogenic response. | We have studied the mechanism of the cell-mediated mitogenic response (CMMR), in which proliferative responses are generated in mouse T lymphocytes co-cultivated with syngeneic mitomycin C-treated spleen cells (Mito-SP), when either responder or stimulator cells are briefly pretreated with concanavalin A (Con A) under ... | 305,446 | [

Control of human B lymphocyte responsiveness: enhanced suppressor T cell activity after in vitro incubation. | Human peripheral blood mononuclear cells (PBM) lost the capacity to generate immunoglobulin-secreting cells (ISC) in response to pokeweed mitogen (PWM) after a period of preincubation in vitro.
