, the cells have been incubated for 30 min with anti-CD62P principal antibody diluted at a ratio of 1:one hundred in PBS containing 1 bovine serum albumin (BSA). Right after washing three instances with PBS, the cells have been incubated with FITC-labeled secondary antibody in PBS containing 1 BSA for 30 min in the dark, washed once more with PBS, and analyzed by flow cytometry (BD, Biosciences, USA).two.5.two. Competitive inhibition assayWhen HOKs reached 800 confluence in six-well plates, they had been incubated with two lg/mL LPS for 36 h. Immediately after the addition of anti-CD62p major antibody (two lL/mL) to block cellular receptors, the HOKs were treated for four h with DOXloaded FD nanomicelles (DOX/FD) in which the concentration of DOX was 0.5 lg/mL, digested with trypsin, washed with PBS, and measured by flow cytometry. HOKs devoid of receptor blocking had been utilized as control.Figure three.

HOKs have been cultured in 12well plates, and when the cells reached 800 confluence, they have been incubated with two lg/mL LPS for 36 hours. Then HOKs have been incubated with anti-CD62P principal antibody at a concentration of two lL/mL for 2 h. Soon after replacing the medium, cells have been incubated with CBD/FD (CBD, 15 lg/mL) for four h. The cells were again stimulated with two lg/mL LPS for 36 h soon after the medium was replaced, then inflammatory factors IL1b and TNF-a within the cell culture medium were detected by ELISA.Then a rounded filter paper having a diameter of three mm was immersed in 50 acetic acid and placed for two min around the front one-third of the tongue abdomen of mice anesthetized with 4 chloral hydrate (Nodai et al., 2018).two.7. Evaluation of inflammation-targeting capability in vivoIn vivo inflammation-targeted capacity of FD was evaluated by two administration pathways like intravenous injection and in situ dripping. Eight mice have been randomly divided into two groups by random quantity sequence (n four per group). Free DOX or DOX/FD (DOX: 2 mg/mg), which had been ready comparable to CBD/FD, were then injected via the tail vein at 36 h soon after ulcer creation. The mouse tongues were collected at four and 12 h post-administration. For in situ dripping, 18 mice have been randomly divided into two groups (n 9 per group) at 36 h following ulcer creation.2.6. Om mouse modelTo establish the in vivo OM model, C57BL6 mice were intraperitoneally injected with 50 mg/kg 5-Fu (Im et al., 2019).Figure 4.
