Does vascular smooth muscle cell-selective peroxisome proliferator-activated receptor-gamma deletion lead to hypotension?
These data uncovered the beta2-AdR as a novel target of PPARgamma transcriptional repression in vascular smooth muscle cells and indicate that PPARgamma regulation of beta2-adrenergic signaling is important in the modulation of BP.
Our results suggest that recent exposure to NO(2) and possibly O(3) may reduce the response to SABAs in producing bronchodilation in children with asthma. The association between NO(2) and FEV(1) response to SABA administration may have important implications in understanding how outdoor air pollution levels relate to asthma control.
