Objective:
This in vitro investigation assessed the role of gallic acid in regulating macrophage polarization.
Design:
In this study, RAW264.7 macrophages were treated with P. gingivalis lipopolysaccharide (LPS) to mimic inflammatory conditions in periodontitis. Immunofluorescence staining, enzyme‑linked immunosorbent (ELISA) assay, RNA sequencing, and seahorse metabolic profile assay were used to assess the effects of gallic acid on macrophage polarization, cytokine release, underlying mechanism and metabolic profile.
Results:
The study demonstrated that treatment with gallic acid could induce M2 polarization of macrophages (P < 0.01) and increase the production of anti-inflammatory cytokines (P < 0.01). Analysis of RNA sequencing data showed enrichment of mitochondrial oxidative phosphorylation, regulation of metabolic processes, and the PI3K-Akt signaling pathway in LPS-treated macrophages treated with gallic acid. Furthermore, gallic acid was found to enhance mitochondrial oxidative phosphorylation activity through the PI3K-Akt signaling pathway in RAW264.7 cells.
Conclusions:
Gallic acid treatment has the potential to promote M2 polarization of macrophages by modulating mitochondrial oxidative phosphorylation via the PI3K-Akt signaling pathway.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
