Ribonucleoparticle (i.e. ribosome and SRP)-independent transport of proteins into mammalian microsomes is stimulated by a cytosolic ATPase which involves proteins belonging to the hsp70 family. Here...
The import of small precursor proteins, derived from the honeybee secretory protein prepromelittin, into dog pancreas microsomes is independent of signal recognition particle (SRP) and docking...
Zimmermann, R, Sagstetter, M, Lewis, M J, Pelham, H R
Processing of M13 procoat protein, synthesized in a bacterial cell-free extract, to transmembrane coat protein by dog pancreas microsomes is stimulated by a system which is present in rabbit...
Frog prepropeptide GLa, a precursor to a secretory protein containing 64 amino acids, was processed and imported by dog pancreas microsomes. These events did not depend on either docking protein or...
Wiech, H, Sagstetter, M, Müller, G, Zimmermann, R
M13 procoat protein is processed to transmembrane coat protein by dog pancreas microsomes after completion of synthesis and in the absence of the signal recognition particle (SRP)/docking protein...
Honeybee prepromelittin is correctly processed and imported by dog pancreas microsomes. Insertion of prepromelittin into microsomal membranes, as assayed by signal sequence removal, does not depend...
Wang, X, Greilberger, J, Levak-Frank, S, Zimmermann, R, Zechner, R, Jürgens, G
It has been well established that purified lipoprotein lipase (LPL) can facilitate the cellular uptake of various native and modified lipoproteins when added exogenously to macrophages. Because...

OBJECTIVE—To determine the levels of vascular endothelial growth factor (VEGF) mRNA and protein expression in normal and osteoarthritic (OA) human articular cartilage, and whether VEGF expression...
Tiefenbacher, C. P., Tillmanns, H., Niroomand, F., Zimmermann, R., Kübler, W.
OBJECTIVE: To investigate the role of endothelial vasodilating factors in adaptation of myocardial blood flow to increased metabolic demands. DESIGN: Alterations in the effects of endothelium...
Troponin T release after heart transplantation.
Zimmermann, R, Baki, S, Dengler, T J, Ring, G H, Remppis, A, Lange, R, ...
BACKGROUND--For the diagnosis of myocardial cell damage the measurement of the serum concentrations of myofibrillar antigens has several potential advantages over the assessment of traditional...
Neumann, F J, Tillmanns, H, Roebruck, P, Zimmermann, R, Haupt, H M, Kübler, W
Plasma viscosity, photometric erythrocyte aggregation index, and erythrocyte filterability were measured in 194 patients with coronary artery disease. Patients with unstable angina (n = 64) had a...
Licka, M, Zimmermann, R, Zehelein, J, Dengler, T J, Katus, H A, Kübler, W
Background: After acute myocardial infarction, the structural protein T is released considerably longer than cytosolic creatine kinase (CK), CK MB isoenzyme (CK-MB), or lactate dehydrogenase (LDH)...
Defective IL-6 secretion in HIV-infected haemophilia patients.
Weimer, R, Zipperle, S, Daniel, V, Zimmermann, R, Opelz, G
To study the role of IL-6 in HIV-induced B cell defects, in vitro B cell responses and IL-6 secretion were determined simultaneously in 67 haemophilia patients. Twenty-three patients were HIV- (Group...
Daniel, V, Süsal, C, Weimer, R, Zimmermann, R, Huth-Kühne, A, Opelz, G
The mechanism of CD4+ cell depletion and functional T helper cell inhibition in HIV-infected individuals is poorly understood. The present study demonstrates that immune complex-covered CD4+ cells...
DANIEL, V, SADEGHI, M, NAUJOKAT, C, WEIMER, R, HUTH-KÜHNE, A, ZIMMERMANN, R, ...
It is believed that autoimmune phenomena and apoptosis contribute to CD4 depletion. We investigated 11 long-term (>20 years) HIV-infected haemophilia patients and 10 healthy controls. Using...
Weimer, R, Zipperle, S, Daniel, V, Zimmermann, R, Schimpf, K, Opelz, G
To analyse CD4 cell cytokine secretion and helper/suppressor function at a clonal level we established 446 CD4+ T cell clones (TCC) in four healthy controls, three HIV− haemophilia patients, four...
Daniel, V, Melk, A, SÜsal, C, Weimer, R, Zimmermann, R, Huth-KÜhne, A, ...
The predominant immunological finding in HIV+ haemophilia patients is a decrease of CD4+ lymphocytes during progression of the disease. Depletion of CD4+ lymphocytes is paralleled by an increase in...
Cytosolic and ER J-domains of mammalian and parasitic origin can functionally interact with DnaK
Nicoll, W.S., Botha, M., McNamara, C., Schlange, M., Boshoff, A., ...
Both prokaryotic and eukaryotic cells contain multiple heat shock protein 40 (Hsp40) and heat shock protein 70 (Hsp70) proteins, which cooperate as molecular chaperones to ensure fidelity at all...
Cimetidine does not increase the anticoagulant effect of phenprocoumon.
Harenberg, J, Staiger, C, De Vries, J X, Walter, E, Weber, E, Zimmermann, R
In patients on oral warfarin, nicoumalone and phenindione an increase of the anticoagulant effect has been described during concomitant treatment with cimetidine. Therefore we have investigated the...
