Improvement effect and mechanism of ginsenoside F1 on allergic rhinitis rats based on the MAPK/STAT3 pathway
To explore the improvement effect and potential mechanism of ginsenoside F1 (GF1) on allergic rhinitis (AR) rats based on the mitogen-activated protein kinase (MAPK)/signal transducer and activator of transcription 3 (STAT3) pathway.
METHODS
2
Male SD rats were divided into a control group (
n
=15) and a modeling group (
n
=55). The AR rat model was established by basic sensitization with ovalbumin followed by local challenge. The successfully modeled rats were randomly assigned to the AR group, low-dose GF1 group [2.5 mg/(kg·d)
]
, high-dose GF1 group [5 mg/(kg·d)
]
, loratadine group (positive control, 1.5 mg/(kg·d)
]
, and high-dose GF1+MAPK activator group [5 mg/(kg·d) GF1+0.2 nmol C16-PAF
]
, with 10 rats in each group. Another 10 rats from the control group were randomly selected as the blank control group. Rats in each group received corresponding drug solutions or normal saline via intranasal instillation and/or oral gavage once daily for 28 consecutive days. After the final administration, AR symptoms were observed and rhinitis symptom scores were assessed. Histopathological changes of the nasal mucosa were examined. The number of inflammatory cells in nasal lavage fluid, serum levels of inflammatory cytokines [interleukin-4 (IL-4), IL-17, interferon-γ (IFN-γ)
]
and immunoglobulin E (IgE), as well as the density of goblet cells, the number of mast cells, and the expression of MAPK/STAT3 pathway-related proteins in nasal mucosal tissues were measured.
RESULTS
2
Compared with the blank control group, the AR group exhibited marked pathological damage to the nasal mucosal epithelium, characterized by interstitial edema and inflammatory cell infiltration. The rhinitis symptom score, the number of macrophages, lymphocytes, eosinophils, neutrophils and mast cells, the density of goblet cells, the levels of IL-4, IL-17 and IgE, as well as the protein phosphorylation levels of p38 MAPK and
STAT3 were significantly increased or elevated, while the level of IFN-γ was significantly decreased in the AR group (
P
<0.05). Compared with the AR group, all administration groups showed recovery of nasal mucosal epithelial pathological damage and significant improvements in all quantitative indicators, with the high-dose GF1 group and loratadine group showing more pronounced improvements than the low-dose GF1 group (
P
<0.05). C16-PAF significantly reversed the ameliorative effects of GF1 on all quantitative indicators (
P
<0.05).
CONCLUSIONS
2
GF1 can alleviate rhinitis symptoms in AR rats and inhibit inflammatory responses, which may be related to the inhibition of the MAPK/STAT3 pathway activation.
