m467: a murine iga myeloma protein that binds a bacterial protein. i. recognition of common antigenic determinants on salmonella flagellins.	we have studied the binding of m467, an iga murine myeloma protein, to flagellin from seven species of salmonella. it was found that m467 was reacting with antigenic determinants that were common to all the flagellins studied. these determinants were not related to serotypic antigens. electronmicrographs of unreduced m467 showed a variety of polymeric species bound to flagella in a manner that could produce immobilization as well as agglutination and precipitation through cross-linking of antige ...	1979	90100
characterization of in vitro proliferative responses of human lymphocytes to leishmanial antigens.	leishmaniasis is an intracellular protozoal infection for which host defense is believed to depend on cellular immune mechanisms. the in vitro proliferative responses of lymphocytes from patients with leishmaniasis and from control subjects to leishmanial antigens were examined. only lymphocytes from patients responded to 1 microgram of leishmanial antigen/ml, whereas both patient and control lymphocytes responded to 10 micrograms/ml. the nonspecific responses were most likely not due to a mitog ...	1979	90105
differential growth inhibition in two human carcinoma cell lines by cyclic adenosine 5'-monophosphate analogs.	the inhibition of cell replication in two human carcinoma cell lines by various cyclic amp analogs was explored. in all instances, the addition of the cyclic nucleotide phosphodiesterase inhibitor 1-methyl-3-isoburylxanthine resulted in synergistic growth inhibition by the analogs. a correlation was found between an analog's ability to inhibit growth and its ability to activate protein kinase. a differential effect of the breakdown product 8-bromo-amp (8-bramp) on cell replication in the two cel ...	1979	90151
biosynthesis of an unglycosylated envelope glycoprotein of rous sarcoma virus in the presence of tunicamycin.	cells stably infected with rous sarcoma virus were treated with tunicamycin to prevent the glycosylation of the precursor (pr92gp) to the two viral envelope glycoproteins gp85 and gp35. pretreatment of the cells for 4 h with the antibiotic resulted in a 90% reduction in [3h]mannose incorporation into total cellular glycoproteins, intracellular viral glycoproteins, and released virus particles. protein synthesis and virus particle formation were not significantly affected by the treatment. a new ...	1979	90167
