Because of its low molecular weight, TAP is rapidly excreted in urine and is easily detected in both urine and serum. 2007-03-27 To isolate the potential contribution of proteases to lung injury, trypsin or trypsinogen was injected into healthy rats or trypsinogen secreted in caerulein pancreatitis was activated by intravenous enterokinase.

Pulmonary injury induced by protease infusions was dose dependent and was ameliorated by … the initial rate of activation, the reaction was followed during a time sufficiently short so that only about 5 o/o of chymotrypsinogen was transformed into chymotrypsin. For the activations in the presence of Ca2+, the phosphate buffer was replaced by a 0.01M Tris-C1 buffer. Trypsinogen Activation by Trypsin Trypsinogens are pancreatic proteases that can initiate the autodigestive cascade characterizing acute pancreatitis. TAP corresponds to the Nterminal region of the peptide released by the activation of trypsinogen into active trypsin (Figure 1). trypsinogen activation (20–22). The site of activation may be organelles that are formed by fusion of secretory vesicles and lysosomes, and the lysosomal enzyme cathepsin B could be responsible for the trypsinogen activation (9, 16, 23–30). Colo-calization of trypsinogen and cathepsin B was reported for Trypsinogen activation peptide (TAP) is a five amino acid compound of trypsinogen that is liberated during the activation of trypsinogen (1).

Trypsinogen is activated to trypsin in a reaction, where TAP is cleaved off and thus, can be used as a marker of trypsinogen activation . The RIA was performed as described previously [ 27 ].

Figure 2. The intrapancreatic activation of trypsinogen into active trypsin is a process regulated by at least two distinct mechanisms. 1. The PSTI (pancreatic  – Converts trypsinogen to its active form trypsin. Trypsin, which is itself another proteolytic enzyme, activates the precursor zymogens (such as chymotrypsinogen)  Trypsinogen is activated by the enzyme enterokinase, which is embedded in the intestinal mucosa.
