CAP18 (18-kDa cationic antimicrobial protein) is a protein originally identified and purified from rabbit leukocytes on the basis of its capacity to bind and inhibit various activities of lipopolysaccharide (LPS). Here we report the cloning of human CAP18 and characterize the anti-LPS activity of the C-terminal fragment. Oligonucleotide probes designed from(More)
Staphylococcus aureus causes pathologies ranging from minor skin infections to life-threatening diseases. Pathogenic effects are largely due to production of bacterial toxin, which is regulated by an RNA molecule, RNAIII. The S. aureus protein called RAP (RNAIII activating protein) activates RNAIII, and a peptide called RIP (RNAIII inhibiting peptide),(More)
The present studies describe a new function for calmodulin-dependent protein kinase II (CaM-KII) in signal transduction leading to apoptosis. Both tumor necrosis factor alpha (TNF) and UV light rapidly stimulated Ca2+-independent activity of CaM-KII in the monocytic leukemia, U937. Two mechanistically different inhibitors of CaM-KII blocked activation of(More)
OBJECTIVES To determine if an educational intervention in the acute stage of whiplash injury may improve the recovery rate. METHODS Consecutive subjects were randomized to one of two treatment groups: educational intervention or usual care. The intervention group received an educational pamphlet based on the current evidence. The control group did not(More)
The present study was undertaken to evaluate the possible contribution of other cytokines to the lytic activity of NKCF-containing supernatants. We compared some of the functional properties of human NKCF and purified recombinant human rLT and rTNF. It was found that the target cell specificity of rLT was quite different from NKCF in that rLT was neither(More)
A cationic antimicrobial protein of 18 kDa (CAP18) was originally isolated from rabbit granulocytes by using as an assay the agglutination of Re-lipopolysaccharide-coated erythrocytes. The C-terminal 37 amino acids of CAP18 (CAP18(106-142)) make up the lipopolysaccharide-binding domain. Synthetic CAP18(106-142) has broad antimicrobial activity against both(More)
The 24-kD apoptotic protease (AP24) is a serine protease that is activated during apoptosis and has the capacity to activate internucleosomal DNA fragmentation in isolated nuclei. This study examined the following: (a) the functional relationship between AP24 and the CPP32-like proteases of the caspase family; and (b) whether activation of CPP32-like(More)
Many intracellular pathways are set in motion by the binding of tumor necrosis factor (TNF) to its cell surface receptor. Major steps in the TNF-mediated cytotoxicity cascade include G protein-coupled activation of phospholipases, generation of free radicals, and damage to nuclear DNA by endonucleases. Ultimately the cells undergo apoptosis and die.(More)
CAP18 (cationic antimicrobial protein, 18kDa) is a 142 amino acid protein originally isolated from rabbit granulocytes using agglutination of LPS-coated erythrocytes as an assay. CAP-18 is composed of an N-terminal domain of unknown function (CAP181-105) and a C-terminal LPS-binding domain (CAP18106-142). Synthetic CAP18106-142 and CAP18106-137, a 32-amino(More)
A prospective controlled comparison of portal-systemic (PSS) and distal splenorenal shunts (DSRS) in cirrhotic patients who had survived hemorrhage from esophagogastric varices was undertaken 5 yr ago at five hospitals by the Boston-New Haven Collaborative Liver Group. The clinical and endoscopic criteria for massive hemorrhage were satisfied in 155(More)
