Ur different protease activated receptors (PARs). PAR-1-deficient mice. PAR-2-deficient mice. PAR-3-deficient mice. PAR-4-deficient mice. In each experiment, footpad swelling was assessed in the PAR-deficient mice and their littermates (+/+ or +/-) as controls.<p><b>Copyright information:</b></p><p>Taken from "Essential role of platelet activation via protease activated receptor 4 in tissue factor-initiated inflammation"</p><p>http://arthritis-research.com/content/10/2/R42</p><p>Arthritis Research & Therapy 2008;10(2):R42-R42.</p><p>Published online 15 Apr 2008</p><p>PMCID:PMC2453761.</p><p></p
