F
as is an apoptosis-signaling receptor molecule expressed in vivo on thymocytes, liver, heart, and ovary. In vivo administration of the anti-Fas Jo2 antibody in mice induces severe apoptotic liver damage leading to fulminant hepatitis and death. Linomide, a quinoline 3-carboxamide, inhibits apoptosis of B and T cells induced by various stimuli including viruses, superantigens, and glucocorticoids. Mice treated with linomide survived the lethal effect of anti-Fas antibody, did not accumulate ceramide in hepatocytes, and recovered liver structure and function within 96 h of anti-Fas injection, as confirmed by histology and glutamic oxalacetic transaminase, glutamic pyruvic transaminase, and lactate dehydrogenase levels. Surviving mice showed severe depletion of cortical thymocytes, but medullar thymic cells expressing high CD3 and Fas levels also survived the treatment with anti-Fas in the presence of linomide. Heart, lung, and ovary showed no signs of apoptosis promoted by Fas ligation. These results suggest that linomide prevents cell death triggered by Fas ligation and can be useful for therapeutic intervention in fulminant hepatitis.

Having trouble reading a PDF?
PDFs are designed to be printed out and read, but if you prefer to read them online, you may find it easier if you increase the view size to 125%.
Having trouble saving a PDF?
Many versions of the free Acrobat Reader do not
allow Save. You must instead save the PDF from the JCI Online page you downloaded it from. PC users:
Right-click on the Download link and choose the option that says something like "Save Link As...".
Mac users should hold the mouse button down on the link to get these same options.
Having trouble printing a PDF?
- Try printing one page at a time or to a newer printer.
- Try saving the file to disk before printing rather than opening it "on the fly." This requires that you
configure your browser to "Save" rather than "Launch Application" for the file type "application/pdf", and can
usually be done in the "Helper Applications" options.
- Make sure you are using the latest version of Adobe's Acrobat Reader.
