Arg-Gly-Glu-Ser(TFA)

Animal experiment:

Mice[1]Mouse pharyngeal aspiration is performed in the assay. Animals are anesthetized with a mixture of ketamine and xylazine (45 mg/kg and 8 mg/kg, i.p., respectively). Test solution (30 μL) containing LPS (1.5 mg/kg) is placed posterior in the throat and aspirated into the lungs. Control mice are administrated sterile saline (0.9% NaCl). Animals are administered with RGDS or Arg-Gly-Glu-Ser peptide (1, 2.5 or 5 mg/kg, i.p.) once one hour before LPS treatment and sacrificed 4 h post-LPS. Animals are also administered RGDS or Arg-Gly-Glu-Ser peptide (5 mg/kg, i.p.) once at different time points (1 h before or 2 h after LPS treatment) and sacrificed 24 h post-LPS. In addition, animals are administered with αvβ3-blocking mAbs, anti-αv, or anti-β3 (5 mg/kg, i.p.) once 1 h before and sacrificed 4 h post-LPS. Animals administered with these mAbs 2 h after LPS treatment are sacrificed 24 h post-LPS[1].
