PMID: 10974209
This study was undertaken to identify the adenosine receptor (AR) subtypes which down-regulate the proinflammatory activities of human neutrophils, as well as the involvement of adenosine 3',5'-cyclic monophosphate (cAMP) and...

Br J Pharmacol
. 2000 Jun;
130(4):717-24.
PMID: 10864876
We have investigated the effects of the adenosine A(2A) receptor agonist CGS 21680 (0.01 - 1 microM) on reactive oxidant production by, and elastase release from FMLP-activated human neutrophils, as...

67(10):5157-62.
PMID: 10496890
The effects of pathologically relevant concentrations (0.38 to 12.5 microM) of the proinflammatory, Pseudomonas aeruginosa-derived pigment 1-hydroxyphenazine (1-hp) on Ca2+ metabolism and intracellular cyclic AMP (cAMP) in N-formyl-L-methionyl-L-leucyl-L-phenylalanine (FMLP; 1...

Inflammation
. 1998 Jan;
21(6):655-65.
PMID: 9429912
The effects of the bioactive phospholipids (PL), platelet-activating factor (PAF), lyso-PAF, and lysophosphatidylcholine (LPC) on the beat frequency and structural integrity of human ciliated respiratory epithelium were studied in vitro,...

Membrane stabilizing, anti-oxidative interactions of propranolol and dexpropranolol with neutrophils
Anderson R, Ramafi G, Theron A
Biochem Pharmacol
. 1996 Jul;
52(2):341-9.
PMID: 8694859
We have investigated the effects of the beta-adrenoreceptor-blocking agent, propranolol (9-300 microM) on several pro-inflammatory activities of human neutrophils in vitro. Superoxide production by calcium ionophore (A23187)-activated neutrophils was particularly...
