Hyperuricemia is accompanied by elevated peripheral CD4 + T cells
Scientific Reports(2023)
摘要
Hyperuricemia (HUA) makes a chronic inflammation status, which affects immune cells. The association between HUA and immune cells, such as monocytes and neutrophils, has been extensively studied. However, studies on HUA and lymphocytes are still limited. We selected 1543 healthy participants and 258 individuals with HUA to analyze the correlation between serum uric acid (SUA) levels and immune cells, and 98 healthy participants and 16 individuals with HUA were used to study the relationship between SUA levels and cytokine levels. Then, we used soluble UA to stimulate peripheral blood mononuclear cells in vitro and examined lymphocyte subset counts and activation by flow cytometry. The results revealed that the number of lymphocytes in the HUA group was significantly increased, particularly CD4 + T cell numbers, which were higher than those in the total population ( P = 0.0019), females ( P = 0.0142), and males ( P = 0.0199) of the healthy control group. Concomitantly, interleukin (IL)-4 and IL-10 levels significantly increased in people with HUA ( P = 0.0254; P = 0.0019). In vitro, soluble UA promoted the proliferation and activation of CD4 + T and CD19 + B cells. Thus, HUA is accompanied by elevated peripheral CD4 + T cells and may cause a Th2-dominant immune status.
