实验参考方法
In Vitro

In vitro activity: Azithromycin reduces about 40% of IL-8 mRNA and protein expression in cystic fibrosis (CF) cells reaching the levels of non-CF cells. Azithromycin results in 50% and 70% reduction of NF-kappaB and AP-1 DNA binding, respectively, leading to levels of non-CF cells. Azithromycin significantly enhances the intensity of a co-stimulatory molecule, CD80, on DCs but not CD86 and CD40 in dendritic cells (DCs). Azithromycin significantly increases the production of IL-10 and Clarithromycin (CAM) significantly inhibits the production of IL-6 by DCs. Azithromycin increases IL-10 and CAM decreases IL-2 productions significantly, when naive T cells derived from spleen are co-cultured with DCs treated in advance with LPS and these macrolides. Azithromycin selectively inhibits fluid-phase endocytosis of horseradish peroxidase and lucifer yellow in J774 mouse macrophages. Azithromycin delays sequestration of receptor-bound transferrin and peroxidase-anti-peroxidase immune complexes into cell-surface endocytic pits and vesicles. Azithromycin down-regulates cell surface transferrin receptors, but not Fc gamma receptors, by causing a major delay in the accessibility of internalized transferrin receptors to the recycling route, without slowing down subsequent efflux, resulting in redistribution of the surface pool to an intracellular pool. Azithromycin inserts into the DOPC lipid bilayer, so as to decrease its cohesion and to facilitate the merging of DPPC into the DOPC fluid matrix.


Cell Assay: THP-1 cells (106 cells in 1 mL RPMI medium, without antibiotics, growth factors or serum) are seeded in each well of 24-well plates and allowed to settle for 1 hour. Next, 50 μL of the test compound is added followed by 50 μL of LPS (final concentration of 10 μg/mL). After 24h (37°C and 5% CO2) the supernatants and cell pellets are collected (1200 rpm, 5 min). THP-1 cell viability is tested using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). MTT is dissolved at 2 mg/mL in PBS and aliquots are stored at -20°C. The MTT assay is performed according to the suppliers instructions. Absorbance of MTT converted into formazan is measured at a wavelength of 570 nm with background subtraction at 630 nm.

In VivoAzithromycin (50 mg/kg) has no effect on bronchoalveolar lavage inflammatory parameters and LDH levels in a mouse model of asthma exacerbation. Azithromycin induces neither general inflammatory parameters nor LDH release in a mouse model of asthma exacerbation, and augments expression of interferon-stimulated genes and the pattern recognition receptor MDA5 but not RIG-I in exacerbating mice
