FIGURE 2.
NGF levels are increased by tryptase but not by SLIGKV. Using ELISA techniques, we detected that tryptase (100 and 1000 ng/ml) but not the agonist peptide SLIGKV (10 and 100 μm) statistically significantly augmented NGF levels after 24 h. Results are means (bars) plus S.E. are from n = 10 individual HTPC/-F cultures and were normalized to untreated controls. *, p < 0.05; **, p < 0.01.
