Assay of Soluble Tumor Necrosis Factor Receptors
2003Over the last decade, numerous basic biological as well as experimental and clinical studies have firmly established the significance of tumor necrosis factor (TNF) as a principal proximal mediator of sepsis (1-4). One of the major insights that has emerged during recent years has been that under physiological circumstances, TNF activity is tightly ...

Soluble factor activation of human B lymphocytes
Nature, 1981Medium conditioned by lectin (and/or antigen)-stimulated human peripheral blood lymphocytes has been shown to contain factors, termed interleukin 1 (IL-1) and interleukin 2 (IL-2)1,2, which augment and maintain human T-cell proliferation3–6, respectively.

Cytokines — soluble factors in immune responses
Current Opinion in Immunology, 1988In the past a great deal of research in immunology was based on the premise that antigens were solely responsible for intracellular events leading to proliferation and differentiation, and that cell contact, antigen receptor ideotypic network, suppressor T cells and antigen specific helper and suppressor factors were the regulators of the immune ...

MACROPHAGE‐LYMPHOCYTE INTERACTIONS MEDIATED BY SOLUBLE FACTORS*
Annals of the New York Academy of Sciences, 1979Adherent-cell-depleted primed rabbit splenocytes were capable of mounting an in vitro response to SRBC. The addition of alveolar macrophages (AM) to adherent-cell-depleted or unseparated lymphoid cell populations resulted in significant suppression of the PFC response. Suppressive activity was limited to AM and dependent on the presence of a ratio of 1

The solubility properties of granulopoiesis inhibiting factor
Experientia, 1975The solubility of granulopoiesis inhibiting factor (GIF) in various aqueous and organic solvents was investigated. GIF is soluble in water, 10% acetic acid, and 10% pyridine. It is not extractable by 1-butanol at low and high pH. A high solubility was found in polar organic solvents (ethanol-acetone 9:1, and chloroform-methanol 1:1), whereas GIF seems ...

Soluble Receptors for Cytokines and Growth Factors
International Archives of Allergy and Immunology, 1996Soluble cytokine and growth factor receptors are currently believed to play an important role in the regulation of biological activities of their ligands. In this review, the current ideas on the mechanisms and regulation of generation of soluble receptors and their possible physiological functions are presented.

Soluble immunosuppressor factors in human cancer
Clinical Immunology Newsletter, 1988An effective immunologic destruction of tumors does not take place in most cases, despite the fact that many cancers display antigenic properties and, generally, the host immune system is affected by a complex functional defect. One of the postulated mechanisms of immune suppression in cancer patients is the presence, in body fluids, of soluble factors

Solubility factors in gas-liquid chromatography
Journal of Chromatography A, 1976Abstract Solubility factors in gas-liquid chromatography have mainly been determined by the work of two groups of workers: Snyder, Karger and Eon through an expanded version of the Hildebrand solubility parameter, and Laffort, Patte and Etcheto through a computer program related to factor analysis.

Soluble-Factor Induction of B-Cell Growth
1985Despite a detailed knowledge of the antigen-specific receptor expressed on the membrane of B lymphocytes, the precise mechanism by which B lymphocytes are activated during an antigenic encounter has remained an area of controversy. Contending viewpoints originally attributed induction of proliferation to the delivery of signals at membrane-bound ...
