Tryptase Is Not Cleared by the Kidneys into the Urine [PDF]

International Archives of Allergy and Immunology, 2009
<i>Background:</i> Patients with chronic kidney disease have been reported to have increased concentrations of blood tryptase. Detection of tryptase in the urine of healthy subjects has been reported. <i>Objective:</i> The objective is to determine whether tryptase is indeed cleared by the kidneys.

Tear Tryptase in Vernal Keratoconjunctivitis [PDF]

Archives of Ophthalmology, 2001
To determine the tear level of tryptase (a marker of mast cell activation) in vernal keratoconjunctivitis (VKC) before and after treatment. In addition, eosinophil counts in conjunctival scrapings and ocular surface temperature before and after treatment were studied.A total of 20 patients, 7 years or older with VKC, were included in this study.

A Role for Tryptase in the Activation of Human Mast Cells: Modulation of Histamine Release by Tryptase and Inhibitors of Tryptase

The Journal of Pharmacology and Experimental Therapeutics, 1998
Tryptase, the most abundant protein product of human mast cells is emerging as an important mediator and target for therapeutic intervention in allergic disease. We have investigated the potential of tryptase and inhibitors of tryptase to modulate histamine release from human mast cells.
