Isoptin and lidocaine (a local anaestetic) inhibited repolymerisation of tubulin into microtubules and induced depolymerisation of microtubules. Isoptin and lidocaine inhibited competitively binding of colchicine (a classical microtubules disrupting agent) to tubulin. Isoptin induced changes in the plasma membrane topography resembling effects caused by local anaesthetics or by a combination of colchicine and cytochalasin B (an agent affecting microfilament function). Isoptin, lidocaine, colchicine and hydroxyurea when present in the culture medium during the whole incubation period inhibited DNA synthesis induced by lipopolysaccharide or Concanavalin A. RNA synthesis was completely inhibited by lidocaine but not by Isoptin or by colchicine. If Isoptin, colchicine or hydroxyurea were removed from the culture medium at 20 h of culture period, the cells immediately started to incorporate 3H-Thymidine. The inhibitory action of lidocaine was irreversible. These results show that Isoptin, a drug which depolymerizes microtubules in vitro and disturbs the mitogen induced changes in plasma membrane topography of lymphocytes (believed to be controlled by microtubules and microfilaments), does not abolish commitment of the cells for DNA synthesis.</p>","PeriodicalId":23935,"journal":{"name":"Zeitschrift fur Immunitatsforschung.

Erythrocyte adherence to the marginal zone of mouse spleen follicle mediated by receptor(s) for neuraminic acid. 神经氨酸受体介导的小鼠脾滤泡边缘区红细胞粘附。

This adherence reaction (AR) is not restricted to red blood cells but is also observed with human lymphocytes. Pretreatment of the tissue sections with trypsin, mercaptoethanol, periodate, chloroform/methanol, acetone, and heating the sections abolishes AR whereas neuraminidase (VCN) treatment of the sections has an amplifying effect. AR is inhibited by preincubation of the neuraminidase- or untreated sections with neuraminic acid (NA). Treatment of the erythrocytes with VCN completely abolishes AR whereas treatment with other enzymes (hyaluronidase, collagenase) is ineffective in this respect. Determination of NA in the erythrocyte membrane before and after VCN treatment reveals a positive correlation between the amount of NA and AR. Rabbit red blood cells have the lowest NA content in their membranes and, in addition, there is little effect of VCN treatment in further reducing it. It is possible that a lectin-like substance is responsible for AR. The biologic significance of AR is hypothetical, but since AR occurs in an area of the spleen playing a role in antigen trapping it is conceivable that this trapping may be mediated by interaction of NA and NA receptor(s).</p>","PeriodicalId":23935,"journal":{"name":"Zeitschrift fur Immunitatsforschung.

Stimulation of humoral immunity by peptidoglycan monomer from Brevibacterium divaricatum. 短杆菌肽聚糖单体对体液免疫的刺激作用。

The PFC response was evidently stimulated. The counts were increased to practically the same extent over a great range of doses of PGM (from 25 to 1600 microgram per animal), and the effect was present in the mice immunised with optimal, as well as in those immunised with suboptimal, doses of antigen. The magnitude of the immunostimulation depend only on the timing of PGM administration: it was maximal if PGM was injected 1 or 2 days after the antigen. In vitro, in a 4-day culture of spleen cells, PGM did not stimulate PFC formation. We conclude that stimulation of the humoral immune response to sheep red blood cell antigens by PGM probably occurs without cell multiplication and probably involves more than simply a contact of immunocompetent cells with PGM.</p>","PeriodicalId":23935,"journal":{"name":"Zeitschrift fur Immunitatsforschung.

75Se-release: a short and long term assay system for cellular cytoxicity. 硒释放:一种细胞毒性的短期和长期测定系统。

{"title":"75Se-release: a short and long term assay system for cellular cytoxicity.","authors":"W Leibold,&nbsp;S Bridge","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The gamma-emitting aminoacid 75Se-selenomethionine (75SeM) was examined as a target cell label in cytotoxic assays. It was efficiently taken up by activated, intensively metabolizing cells of various types but hardly at all by resting or low-metabolizing cells. Culturing activated cells in methionine-deficient medium with 3--5 mu Ci75SeM/ml for 18--22 h usually resulted in an uptake of 3--20 cpm/cell which was 3--200 times that of 51Cr marked cells. 75SeM-labelled cells kept in medium at ambient temperature or at 37 degrees C, maintained a high radioactivity per cell and a viability above 85% for at least 72 h without significant increase in spontaneous isotope release or loss in sensitivity in subsequent cytotoxic tests. 75Se-labelled material released from target cells was not reutilized by unlabelled lymphoid cells. Provided the cells were carefully washed after labelling and kept in optimal culture conditions, the reasonably low baseline release (usually 0.6--1.8% of input/h) in the medium control allowed performance of long-term assays of up to 54 h. However, strong cytotoxic reactions (e.g. ADCC) could cause over 50% specific 75Se-release within 5 h. With constant amounts of effector cells (3.6 x 10(3) up to 3 x 10(5)/well) identical or even higher, specific releases were obtained on 6 x 10(2) targets as compared to 1 x 10(4) targets/well. Thus, the 75Se-release assay offers a single monitoring system suitable for short (3--6 h) and long term (usually up to 44 h) cytotoxic reactions on a microscale, using 1 x 10(3) or less targets/well. Its sensitivity permits evaluation of strong and weak reactions as well as early and delayed onset cytotoxicity. In addition, with a gamma-spectrometer the radioactivity of 75Se can easily be distinguished from that of 51Cr. Due to this, and an improved method for 51Cr labelling of cells (10 mu Ci 51Cr/ml medium for 18--22 h), a double gamma-labelling of cellular proteins is available which provides new possibilities for monitoring cellular interactions in short and long term tests.</p>","PeriodicalId":23935,"journal":{"name":"Zeitschrift fur Immunitatsforschung.

While in agreement with earlier reports, molecular weights of approximately 180,000 daltons were determined by gel filtration at 37 degrees C and below, above 58 degrees C additional AA-antigenic activity was found in the void volume and at the position of approximately 12,000 daltons. The latter polypeptide resembled in size and immunoreactivity SAAL in that it had AA-antigenic determinants exposed at 4 degrees C (unlike SAA). Because the release of SAAL or a similar molecule could not be prevented by the enzyme inhibitor PMSF, a temperature-dependent dissociation of SAA is proposed.
