Figure 1From: Differential regulation of neurotrophin expression in human bronchial smooth muscle cellsConstitutive expression of neurotrophins by non-treated HBSMC evaluated by RT-PCR and ELISA. (A) Expression of NGF, BDNF, NT-3 mRNA and 18S rRNA. Reversed transcribed (RT+) and non-reversed transcribed (RT-) mRNA or rRNA are displayed. (B) NGF (white bars) and BDNF (black bars) protein secretion determined by ELISA. Data presented as mean ± SEM of 3–4 independent experiments performed in duplicate. In (B) ***: p < 0.001 for NGF, and #: p < 0.05 and ##: p < 0.01 for BDNF, versus 2.5 hBack to article page
