Cystic fibrosis transmembrane conductance regulator-mediated corneal epithelial cell ingestion of Pseudomonas aeruginosa is a key component in the pathogenesis of experimental murine keratitis. (1/2621)

Previous findings indicate that the cystic fibrosis transmembrane conductance regulator (CFTR) is a ligand for Pseudomonas aeruginosa ingestion into respiratory epithelial cells. In experimental murine keratitis, P. aeruginosa enters corneal epithelial cells. We determined the importance of CFTR-mediated uptake of P. aeruginosa by corneal cells in experimental eye infections. Entry of noncytotoxic (exoU) P. aeruginosa into human and rabbit corneal cell cultures was inhibited with monoclonal antibodies and peptides specific to CFTR amino acids 108 to 117. Immunofluorescence microscopy and flow cytometry demonstrated CFTR in the intact murine corneal epithelium, and electron microscopy showed that CFTR binds to P. aeruginosa following corneal cell ingestion. In experimental murine eye infections, multiple additions of 5 nM CFTR peptide 103-117 to inocula of either cytotoxic (exoU+) or noncytotoxic P. aeruginosa resulted in large reductions in bacteria in the eye and markedly lessened eye pathology. Compared with wild-type C57BL/6 mice, heterozygous DeltaF508 Cftr mice infected with P. aeruginosa had an approximately 10-fold reduction in bacterial levels in the eye and consequent reductions in eye pathology. Homozygous DeltaF508 Cftr mice were nearly completely resistant to P. aeruginosa corneal infection. CFTR-mediated internalization of P. aeruginosa by buried corneal epithelial cells is critical to the pathogenesis of experimental eye infection, while in the lung, P. aeruginosa uptake by surface epithelial cells enhances P. aeruginosa clearance from this tissue.

Cystic fibrosis-associated mutations at arginine 347 alter the pore architecture of CFTR. Evidence for disruption of a salt bridge. (2/2621)

Arginine 347 in the sixth transmembrane domain of cystic fibrosis transmembrane conductance regulator (CFTR) is a site of four cystic fibrosis-associated mutations. To better understand the function of Arg-347 and to learn how mutations at this site disrupt channel activity, we mutated Arg-347 to Asp, Cys, Glu, His, Leu, or Lys and examined single-channel function. Every Arg-347 mutation examined, except R347K, had a destabilizing effect on the pore, causing the channel to flutter between two conductance states. Chloride flow through the larger conductance state was similar to that of wild-type CFTR, suggesting that the residue at position 347 does not interact directly with permeating anions. We hypothesized that Arg-347 stabilizes the channel through an electrostatic interaction with an anionic residue in another transmembrane domain. To test this, we mutated anionic residues (Asp-924, Asp-993, and Glu-1104) to Arg in the context of either R347E or R347D mutations. Interestingly, the D924R mutation complemented R347D, yielding a channel that behaved like wild-type CFTR. These data suggest that Arg-347 plays an important structural role in CFTR, at least in part by forming a salt bridge with Asp-924; cystic fibrosis-associated mutations disrupt this interaction.

CFTR channel insertion to the apical surface in rat duodenal villus epithelial cells is upregulated by VIP in vivo. (3/2621)

cAMP activated insertion of the cystic fibrosis transmembrane conductance regulator (CFTR) channels from endosomes to the apical plasma membrane has been hypothesized to regulate surface expression and CFTR function although the physiologic relevance of this remains unclear. We previously identified a subpopulation of small intestinal villus epithelial cells or CFTR high expressor (CHE) cells possessing very high levels of apical membrane CFTR in association with a prominent subapical vesicular pool of CFTR. We have examined the subcellular redistribution of CFTR in duodenal CHE cells in vivo in response to the cAMP activated secretagogue vasoactive intestinal peptide (VIP). Using anti-CFTR antibodies against the C terminus of rodent CFTR and indirect immunofluorescence, we show by quantitative confocal microscopy that CFTR rapidly redistributes from the cytoplasm to the apical surface upon cAMP stimulation by VIP and returns to the cytoplasm upon removal of VIP stimulation of intracellular cAMP levels. Using ultrastructural and confocal immunofluorescence examination in the presence or absence of cycloheximide, we also show that redistribution was not dependent on new protein synthesis, changes in endocytosis, or rearrangement of the apical cytoskeleton. These observations suggest that physiologic cAMP activated apical membrane insertion and recycling of CFTR channels in normal CFTR expressing epithelia contributes to the in vivo regulation of CFTR mediated anion transport.

beta3-adrenoceptor control the cystic fibrosis transmembrane conductance regulator through a cAMP/protein kinase A-independent pathway. (4/2621)

In human cardiac myocytes, we have previously identified a functional beta3-adrenoceptor in which stimulation reduces action potential duration. Surprisingly, in cardiac biopsies obtained from cystic fibrosis patients, beta3-adrenoceptor agonists produced no effects on action potential duration. This result suggests the involvement of cystic fibrosis transmembrane conductance regulator (CFTR) chloride current in the electrophysiological effects of beta3-adrenoceptor stimulation in non-cystic fibrosis tissues. We therefore investigated the control of CFTR activity by human beta3-adrenoceptors in a recombinant system: A549 human cells were intranuclearly injected with plasmids encoding CFTR and beta3-adrenoceptors. CFTR activity was functionally assayed using the 6-methoxy-N-(3-sulfopropyl)quinolinium fluorescent probe and the patch-clamp technique. Injection of CFTR-cDNA alone led to the expression of a functional CFTR protein activated by cAMP or cGMP. Co-expression of CFTR (but not of mutated DeltaF508-CFTR) with high levels of beta3-adrenoceptor produced an increased halide permeability under base-line conditions that was not further sensitive to cAMP or beta3-adrenoceptor stimulation. Patch-clamp experiments confirmed that CFTR channels were permanently activated in cells co-expressing CFTR and a high level of beta3-adrenoceptor. Permanent CFTR activation was not associated with elevated intracellular cAMP or cGMP levels. When the expression level of beta3-adrenoceptor was lowered, CFTR was not activated under base-line conditions but became sensitive to beta3-adrenoceptor stimulation (isoproterenol plus nadolol, SR 58611, or CGP 12177). This later effect was not prevented by protein kinase A inhibitors. Our results provide molecular evidence that CFTR but not mutated DeltaF508-CFTR is regulated by beta3-adrenoceptors expression through a protein kinase A-independent pathway. (+info)

Molecular analysis of the cystic fibrosis gene reveals a high frequency of the intron 8 splice variant 5T in Egyptian males with congenital bilateral absence of the vas deferens. (5/2621)

It has previously been shown that defects in the cystic fibrosis transmembrane conductance regulator (CFTR) gene are largely responsible for the condition of congenital bilateral absence of the vas deferens (CBAVD), without associated renal abnormalities, in Caucasian populations. To assess the involvement of the CFTR in CBAVD in a population with presumed low cystic fibrosis (CF) frequency, we have analysed 20 CBAVD males from Egypt for the presence of 12 common Caucasian CFTR mutations and the intron 8 5T splice variant, IVS-5T, known to be a major cause of CBAVD in Caucasian patients. In 16 of the males without associated renal abnormalities only one deltaF508 carrier was identified, but an exceptionally high frequency of the IVS-5T variant was found (14 of 32 alleles or 43.7%), confirming that this variant is involved in many cases of CBAVD, even in populations where CF is rare. CFTR mutations or the IVS-5T variant were found neither in the remaining four patients with associated renal abnormalities nor in the spouses of the 20 CBAVD patients. However, one patient was homozygous for a leucine to proline substitution at amino acid position 541 (L541P) of the CFTR. It is as yet not clear whether this change is involved in CBAVD in this male.

Functional dissection of the R domain of cystic fibrosis transmembrane conductance regulator. (6/2621)

Exogenously expressed unphosphorylated sub-domains of the R domain block CFTR Cl- channels in the planar lipid bilayer, though the block differs from block with full length R domain. Full length R domain peptide (aa 588-855) blocks CFTR Cl- channels quickly, completely and permanently. Two sub-domains, RD1RD2 (aa 588-805) and RD2TM (aa 672-855), also inhibit CFTR Cl- channels, but the block takes longer to effect and is not complete. Shorter sequences, RD1 (aa 588-746) and RD2 (aa 672-805), fail to effect any block. These data suggest that either the amino-terminal or carboxy-terminal portions of the R domain protein or its stabilized secondary structure are critical to functional regulation. (+info)

Chemokine expression in CF epithelia: implications for the role of CFTR in RANTES expression. (7/2621)

To delineate the mechanisms that facilitate leukocyte migration into the cystic fibrosis (CF) lung, expression of chemokines, including interleukin-8 (IL-8), monocyte chemoattractant protein-1 (MCP-1), and RANTES, was compared between CF and non-CF airway epithelia. The findings presented herein demonstrate that, under either basal conditions or tumor necrosis factor-alpha (TNF-alpha)- and/or interferon-gamma (IFN-gamma)-stimulated conditions, a consistent pattern of differences in the secretion of IL-8 and MCP-1 between CF and non-CF epithelial cells was not observed. In contrast, CF epithelial cells expressed no detectable RANTES protein or mRNA under basal conditions or when stimulated with TNF-alpha and/or IFN-gamma (P +info)

A single conductance pore for chloride ions formed by two cystic fibrosis transmembrane conductance regulator molecules. (8/2621)

The cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP-dependent protein kinase (PKA)- and ATP-regulated chloride channel, whose gating process involves intra- or intermolecular interactions among the cytosolic domains of the CFTR protein. Tandem linkage of two CFTR molecules produces a functional chloride channel with properties that are similar to those of the native CFTR channel, including trafficking to the plasma membrane, ATP- and PKA-dependent gating, and a unitary conductance of 8 picosiemens (pS). A heterodimer, consisting of a wild type and a mutant CFTR, also forms an 8-pS chloride channel with mixed gating properties of the wild type and mutant CFTR channels. The data suggest that two CFTR molecules interact together to form a single conductance pore for chloride ions. (+info)
