1978

The localization of amyloid P-components is demonstrated by immunofluorescence microscopy in normal human tissue (kidney, spleen, liver). The relation to collagen and to amyloidosis is discussed.

Wirkungsspektrum des C¯1-Inaktivators aus Meerschweinchenserum

1971

Es wird die Wirkungsweise des C¯1-Inaktivators (I1) gegenuber C¯1 und dem C4 umsetzenden Protein der Euglobulinfraktion (I4) beschrieben. Zum Nachweis der C¯1-Aktivitat wurden vier Nachweismoglichkeiten herangezogen: Die Titration der hamolytischen Wirkung, die Beurteilung des Umsatzes von C4 und C2, sowie die esterolytische Aktivitat gegenuber TAMe. Alle vier Aktivitaten des C¯1 werden durch I1 gehemmt. Daraus ist zu schliesen, das C¯1 eine einheitliche Wirkung ausubt. Diese wird in den Testsystemen in verschiedener Form nachweisbar. Die I4-Aktivitat wird durch I1 in gleicher Form gehemmt wie die C¯1-Aktivitat. Dies spricht fur die Identitat von I4 und der enzymatisch aktiven Untereinheit …

The Receptor Functions of Endogenous C1q, a Subcomponent of the First Component of Complement, on Peritoneal Macrophages

1982

Abstract C1q, the Fc recognizing subcomponent of the first complement component was shown to be synthesized by peritoneal macrophages. Evidence is presented that C1q serves during the secretion phase as Fc binding protein on the membrane of these macrophages. A dose-dependent inhibition of Fc rosette formation occured when the macrophages were pretreated with anti-C1q -F(ab') 2 . The C3b rosette formation was not affected. In addition, preincubation of peritoneal macrophages with anti-C1q -F(ab') 2 abolished specifically the polyanion mediated stimulation to secrete dose and time dependently lysosomal enzymes. There was no polyanion-induced enzyme release after incubation of polyanions with…

Komplementmessungen mit Hilfe des Mikrolitersystems

1969

Es wird die Brauchbarkeit des Mikrolitersystems fur Komplement-Titrationen untersucht. Dabei werden an einer Reihe von Beispielen vergleichende Bestimmungen mit der herkommlichen Makromethode und mit einer fur serologisches Arbeiten adaptierten Mikroliter-Methode ausgefuhrt. Folgende Probleme wurden in die Untersuchung einbezogen: Titration von Vollkomplement und hamolytischen Antikorper; Messung der effektiven Molekulzahl der Einzelkomponenten C′1 und C′2; Bestimmung der Zahl der Amboceptor-sites auf dem sensibilisierten Erythrocyten. Die theoretischen uberlegungen zur Berechnung der Einheiten fur Vollkomplement und Amboceptor werden erlautert. Weiterhin werden die mathematischen Grundlage…

Immunohistological differential diagnosis of inflammatory colonic diseases.

1984

Immunohistological investigations were carried out on human colonic tissue from, I healthy mucosa, 2 slightly inflamed mucosa, 3 mucosa with ulcerative colitis, 4 mucosa with Crohn's colitis, using antibodies against immunoglobulins and complement components. All our antibodies, including F(ab')2 fragments, demonstrated a progressive increase of labelled cells from healthy mucosa through slightly inflamed mucosa to mucosa with ulcerative colitis, in contrast to a complete absence of labelled cells in cases of Crohn's disease. The results are discussed with regard to their pathogenesis and their clinical significance for the differentiation of ulcerative colitis and Crohn's colitis.

Acquired C1 inhibitor (C1-INH) deficiency type II. Replacement therapy with C1-INH and analysis of patients' C1-INH and anti-C1-INH autoantibodies

1989

Abstract The response of two patients with autoantibody-mediated C1-inhibitor (C1-INH) deficiency to replacement therapy with C1-INH was studied over a period of 3 d. In patient 1 an acute attack of angioedema was successfully managed by infusion of 1,000 U of C1-INH concentrate. C1-INH function returned to normal levels within 30 min, while CH50 and C4 peaked after 6-7 h and C1 hemolytic activity reached 50-60% of normal after 3 d. Immediately after the injection an increase in C1-INH-anti-C1-INH complexes was observed. Based on NH2-terminal sequence analysis of the patients' Mr 96,000 C1-INH, it is concluded that this fragment is generated after cleavage of C1-INH in its active site by on…

Studien über den C¯1-Inaktivator des Meerschweinchenkomplements: Meßmethode, Reinigung und Charakterisierung des Proteins

1971

Es wird eine quantitative Nachweismethode fur den C¯1-Inaktivator (I1) aus Meerschweinchenserum beschrieben. Diese beruht auf der Fahigkeit von I1, C¯1 in gebundener Form zu inaktivieren. Es wird eine Reinigungsmethode beschrieben, nach der das I1-Protein 1800fach gegenuber Serum gereinigt werden kann. Das gereinigte Praparat zeigt eine Bande in der analytischen Polyacrylamid-Elektrophorese. I1 hat ein Molekulargewicht von ca. 170000 und eine Sedimentationskonstante von ca. 6,1; durch Erhitzen auf 60° C, durch einen pH-Wert unter 6,0 bzw. uber 8,0 und durch Behandlung mit Ather, Chloroform und Benzol ist die I1-Aktivitat zu inaktivieren. Aufgrund dieser Daten wird ein Vergleich mit dem aus …

Selective Inhibition of Human Natural Killing and Antibody-Dependent Cellular Cytotoxicity by a Polyanion

1987

A high molecular polyanion, Liquoid, was found to inhibit at nontoxic concentrations (12-50 micrograms/ml) the natural killing (NK) and the antibody-dependent cellular cytotoxic (ADCC) activity of human peripheral blood mononuclear cells selectively. Whereas NK of the K 562 target cell was slightly or not at all affected, the spontaneous lysis of PDe-B-1, an EBV-transformed B-cell line, was strongly inhibited or even completely abolished. ADCC activity could only be inhibited by Liquoid if the target cells were mycoplasma-free, while the polyanion had no effect when mycoplasma-contaminated target cells were used. Liquoid did not alter the target binding capacity of the NK effector cells and…
