To investigate the effect of interleukin-1alpha (IL-1alpha) on the phagocytic function in cultured human trabecular meshwork (HTM) cells.
HTM Cells were cultured and subcultured in vitro. The third to fifth passage of HTM cells were treated with different concentrations of IL-1alpha or vehicle in DMEM/F12 medium. 1000 of 0.85 microm microsphere/per cell were added to each well. The morphological changes of HTM cells were observed by an inverted phase-contrast microscope and electron microscope. The cellular phagocytic function of HTM cells was evaluated by counting the numbers of microsphere in 20 HTM cells using a light microscope.
The break of HTM cell membrane was found under the electron microscope. The numbers of microsphere in HTM cells was significantly (P = 0.005) reduced in a dose- and incubation time-dependent manner (F = 3.603, P = 0.046, F = 15.846, P = 0.005, respectively).
IL-1alpha affects the phagocytic function of HTM cells that is correlated to the concentration and the incubation time.
研究白细胞介素-1α(IL-1α)对体外培养的人小梁网(HTM)细胞吞噬功能的影响。
体外培养并传代HTM细胞。将第3至5代HTM细胞在DMEM/F12培养基中用不同浓度的IL-1α或溶剂处理。每孔加入每细胞1000个0.85微米的微球。通过倒置相差显微镜和电子显微镜观察HTM细胞的形态变化。使用光学显微镜通过计数20个HTM细胞中的微球数量来评估HTM细胞的细胞吞噬功能。
在电子显微镜下发现HTM细胞膜破裂。HTM细胞中的微球数量以剂量和孵育时间依赖性方式显著减少(分别为F = 3.603,P = 0.046,F = 15.846,P = 0.005)。
IL-1α影响HTM细胞的吞噬功能,这与浓度和孵育时间相关。
