Specific Inhibition by Rifampicin of Transcription in Human Lymphocytes Stimulated by Phytohemagglutinin

Rifampicin, a semisynthetic antibiotic, is known to inhibit the bacterial DNA-dependent RNA polymerase (1), the growth of some animal viruses (2), and the focus formation induced by oncogenic viruses (3, 4). While certain derivatives of rifampicin can inhibit the RNA-dependent DNA polymerase activity of oncogenic viruses, and a similar activity found in normal and virus-transformed cells (5-7),...

Inhibition of mitosis by chloramphenicol in phytohemagglutinin stimulated lymphocytes.

I TARIOUS CLINICAL AND EXPERIMENTAL STUDIES have shown V that chioramphenicol ( CAP) affects cell division. #{176} The characteristic aplastic marrow that is seen when toxicity is fully expressed suggests a toxic effect leading to depletion of dividing cells. The effect of CAP on incorporation of 32 into phytohemagglutinin ( PHA) stimulated lymphocytes was reported by McIntyre and Ebaugh,’ who ...

Adenosine metabolism in phytohemagglutinin-stimulated human lymphocytes.

The association of a human genetic deficiency of adenosine deaminase activity with combined immunodeficiency prompted a study of the effects of adenosine and of inhibition of adenosine deaminase activity on human lymphocyte transformation and a detailed study of adenosine metabolism throughout phytohemagglutinin-induced blastogenesis. The adenosine deaminase inhibitor, coformycin, at a concentr...

Replication of poliovirus in phytohemagglutinin-stimulated human lymphocytes.

Poliovirus replication has been studied in human lymphocytes during the course of blastogenesis under phytohemagglutinin (PHA) stimulation. Enhancement of virus replication in PHA-stimulated leukocyte cultures was due to an increase in number of virus-producing cells. Virus yield was approximately 10 plaque-forming units (PFU) per producing cell, both in stimulated and in nonstimulated cultures...

Characterization of colony-stimulating activity produced by human monocytes and phytohemagglutinin-stimulated lymphocytes.

Human colony-stimulating activity (CSA) may support the proliferation of both human and murine granulocyte-macrophage progenitor cells (CFU-C) or, in the case of human urinary CSA, may only stimulate murine bone marrow CFU-C. CSA produced in the culture media of monocytes and macrophages and phytohemagglutinin-stimulated lymphocytes from human peripheral blood was characterized for both human a...
