| T1 |
0-130 |
Sentence |
denotes |
Arginase 1 deletion in myeloid cells affects the inflammatory response in allergic asthma, but not lung mechanics, in female mice. |
| T2 |
131-241 |
Sentence |
denotes |
BACKGROUND: (Over-)expression of arginase may limit local availability of arginine for nitric oxide synthesis. |
| T3 |
242-433 |
Sentence |
denotes |
We investigated the significance of arginase1 (ARG1) for the development of airway hyperresponsiveness (AHR) and lung inflammation in female mice with ovalbumin (OVA)-induced allergic asthma. |
| T4 |
434-442 |
Sentence |
denotes |
METHODS: |
| T5 |
443-517 |
Sentence |
denotes |
Arg1 was ablated in the lung by crossing Arg1 fl/fl and Tie2Cre tg/- mice. |
| T6 |
518-632 |
Sentence |
denotes |
OVA sensitization and challenge were conducted, and AHR to methacholine was determined using the Flexivent system. |
| T7 |
633-803 |
Sentence |
denotes |
Changes in gene expression, chemokine and cytokine secretion, plasma IgE, and lung histology were quantified using RT-qPCR, ELISA, and immunohistochemistry, respectively. |
| T8 |
804-812 |
Sentence |
denotes |
RESULTS: |
| T9 |
813-1160 |
Sentence |
denotes |
Arg1 ablation had no influence on the development of OVA-induced AHR, but attenuated OVA-induced increases in expression of Arg2 and Nos2, Slc7a1, Slc7a2, and Slc7a7 (arginine transporters), Il4, Il5 and Il13 (TH2-type cytokines), Ccl2 and Ccl11 (chemokines), Ifng (TH1-type cytokine), Clca3 and Muc5ac (goblet cell markers), and OVA-specific IgE. |
| T10 |
1161-1293 |
Sentence |
denotes |
Pulmonary IL-10 protein content increased, but IL-4, IL-5, IL-13, TNFα and IFNγ content, and lung histopathology, were not affected. |
| T11 |
1294-1464 |
Sentence |
denotes |
Arg1 elimination also decreased number and tightness of correlations between adaptive changes in lung function and inflammatory parameters in OVA/OVA-treated female mice. |
| T12 |
1465-1608 |
Sentence |
denotes |
OVA/OVA-treated female mice mounted a higher OVA-IgE response than males, but the correlation between lung function and inflammation was lower. |
| T13 |
1609-1862 |
Sentence |
denotes |
Arg1-deficient OVA/OVA-treated females differed from males in a more pronounced decline of arginine-metabolizing and -transporting genes, higher plasma arginine levels, a smaller OVA-specific IgE response, and no improvement of peripheral lung function. |
| T14 |
1863-1874 |
Sentence |
denotes |
CONCLUSION: |
| T15 |
1875-2088 |
Sentence |
denotes |
Complete ablation of Arg1 in the lung affects mRNA abundance of arginine-transporting and -metabolizing genes, and pro-inflammatory genes, but not methacholine responsiveness or accumulation of inflammatory cells. |
