Abstract:
The clinical course of gout is typically divided into four stages: asymptomatic hyperuricemia, gout flares, intercritical gout and tophaceous gout. However, the cellular and molecular mechanisms driving transitions between these stages remain unclear. Current clinical practice lacks stage-specific precision therapeutic strategies. In recent years, the development of single-cell sequencing technologies has provided tools to reveal dynamic cell state transitions during gout progression. This review synthesizes existing single-cell evidence to systematically delineate the immune and stromal cell landscapes across the stages of gout, and explores their roles in inflammation initiation, spontaneous resolution, and tissue remodeling, with the aim to provide a theoretical framework for stage-adapted therapies.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
