Abstract:

This study aims to explore the antibacterial activity of Phaseolus vulgaris Linn peptide (PVP) and its inhibitory effect on the transcription of chemokines and inflammatory factors in mouse monocyte macrophages RAW264.7 induced by lipopolysaccharide (LPS). Different mass concentrations of Phaseolus vulgaris Linn peptide were used to treat Staphylococcus aureus and Escherichia coli for 24 hours, and the minimum inhibitory concentration (MIC) and antibacterial circle diameter were detected. Then the CCK-8 kit was used to detect the effect of Phaseolus vulgaris peptide on the viability of RAW264.7 cells. RT-qPCR was used to detect transcription of chemokines (chemokine ligand 2 (CCL2), macrophage inflammatory protein-2 (MIP-2), and chemokine ligand 5 (CCL5)) and inflammatory factors (inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6). Western blotting was used to detect NF-κB activation. The MIC of Phaseolus vulgaris Linn peptide against Staphylococcus aureus and Escherichia coli is 200 μg/mL. Compared with the 0 μg/mL group, the antibacterial circle diameters of Staphylococcus aureus and Escherichia coli increase in 10, 50, 100, 200, 300, 400, and 500 μg/mL groups in a dose-dependent manner (P<0.001). Within the mass concentration range of 1-500 μg/mL, Phaseolus vulgaris Linn peptide has no significant inhibitory or promotional effect on RAW264.7 cell viability (P>0.05). Compared with the LPS group, CCL2, MIP-2, CCL5, iNOS COX-2, TNF-α, IL-1β and IL-6 mRNA relative levels as well as the relative phosphorylation level of NF-κB p65 in RAW264.7 cells in the LPS+10, 50, 100, 200, 300, 400, 500 μg/mL PVP group are all reduced in a dose-dependent manner (P<0.05). This study shows that Phaseolus vulgaris Linn peptide has good antibacterial properties activity, which can effectively inhibit the transcription of chemokines and inflammatory factors in RAW264.7 cells induced by LPS. This study suggests that Phaseolus vulgaris Linn peptide may be a cosmetic additive with good antibacterial and anti-inflammatory activities and has potential development value.
