Exploring strategies to modulate pathological cytokine storms can effectively prevent the development of severe coronavirus infection-induced pneumonia. Treatment with interleukin-37 (IL-37), an anti-inflammatory factor, has unique anti-inflammatory and antiviral effects on infections caused by various pathogens. In this study, we investigated the effect of IL-37 treatment on the SARS-CoV-2 Omicron-infection induced inflammatory response and its molecular mechanism. Our results demonstrated that IL-37 treatment effectively alleviated symptoms, reduced viral loads, suppressed the production of proinflammatory cytokines and chemokines both systemically (in serum) and locally (in the lungs), and attenuated lung lesions and inflammatory cell infiltration in Omicron-infected mice. The suppressed proinflammatory factors were macrophage-related, particularly CCL3 and CCL4, which were significantly inhibited. Furthermore, treatment with IL-37 significantly reduced the proportion of M1-type macrophages in lungs of Omicron-infected mice. In addition, we found that IL-37 targeted M1 macrophages through modulation of the NF-κB signaling pathway to suppress the production of proinflammtory factors during Omicron infection.

Immunologically, MDSCs suppress antitumor responses by inhibiting effector cells such as T cells and NK cells, facilitating immune evasion. Nonimmunologically, they promote tumor growth and metastasis through processes such as the epithelial‒mesenchymal transition, angiogenesis, and premetastatic niche formation. MDSC accumulation is closely linked to accelerated tumor progression, including resistance to both immunotherapies and conventional treatments, making these cells critical therapeutic targets. Clinical studies have demonstrated the potential of MDSC-targeted strategies to improve treatment efficacy. However, challenges remain in achieving specificity and effectiveness in MDSC-targeted therapies, emphasizing the need for a deeper understanding of their biology. This review summarizes the origin, classification, and biological characteristics of MDSCs, their dual roles in tumor progression, and their clinical significance.
