Am J Physiol Gastrointest Liver Physiol
. 2007 Jul;
293(4):G719-28.
PMID: 17640979
Proinflammatory cytokines and eicosanoids are central players in intestinal inflammation. IL-1, a key cytokine associated with intestinal mucosal inflammation, induces COX-2 expression in human colonic myofibroblasts (CMF) and increased prostaglandin...

Am J Physiol
. 1999 Aug;
277(2):C183-201.
PMID: 10444394
Intestinal subepithelial myofibroblasts (ISEMF) and the interstitial cells of Cajal are the two types of myofibroblasts identified in the intestine. Intestinal myofibroblasts are activated and proliferate in response to various...

Am J Physiol
. 1999 Jul;
277(1):C1-9.
PMID: 10409103
Myofibroblasts are a unique group of smooth-muscle-like fibroblasts that have a similar appearance and function regardless of their tissue of residence. Through the secretion of inflammatory and anti-inflammatory cytokines, chemokines,...

J Pharmacol Exp Ther
. 1997 Jun;
281(3):1264-71.
PMID: 9190862
The sensitivity of the Ussing-chambered rat colon to stimulation of Cl- secretion (as measured by the change in short-circuit current) by exogenous platelet-activating factor (PAF) was increased significantly by washing...

Valentich J, Popov V, Saada J, Powell D
Am J Physiol
. 1997 May;
272(5 Pt 1):C1513-24.
PMID: 9176142
Subepithelial myofibroblasts are located at the interface between the epithelium and lamina propria in most mucosal tissues. Their biological functions are largely unknown because a long-term cell culture model for...

PMID: 8997202
The dogfish shark rectal gland (SRG) is histologically complex, containing connective, nerve, and smooth muscle tissue and at least three types of epithelial cells: secretory tubule, central duct, and endothelial....

Am J Physiol
. 1996 Oct;
271(4 Pt 1):C1262-8.
PMID: 8897833
Because interleukin-1 (IL-1) is an important mediator in the inflamed intestine, its effects on enterocyte-subepithelial myofibroblast (SEMF) interaction were investigated in vitro. Acutely juxtaposing T84 cells with 18Co or P2JF...

Am J Physiol
. 1993 Sep;
265(3 Pt 1):C641-9.
PMID: 8214020
Calcium ionophores (ionomycin and A-23187) were employed to assess the effects of increased intracellular Ca2+ concentration ([Ca2+]i) on apical membrane Cl- conductance (GaCl) and rate of transepithelial Cl- secretion in...

Am J Physiol
. 1993 Aug;
265(2 Pt 1):C422-31.
PMID: 8396326
Isoprenylated proteins function in the processes of signal transduction and membrane vesicle trafficking. To investigate the role of isoprenylated proteins in secretagogue-stimulated epithelial ion transport, we studied the effects of...

PMID: 1426050
Laminin is a major component of the basal lamina upon which all epithelial cells reside in vivo. The synthesis of basal lamina components and their subsequent assembly into a morphologically...
