Tumor necrosis factor α is a pleiotropic cytokine that acts on various cell types and has been identified as a key regulator of inflammatory responses, playing a role in the pathogenesis of numerous inflammatory and autoimmune diseases.

The immune system relies on precise regulation to avoid excessive inflammation and autoimmune damage while defending against pathogens and maintaining internal homeostasis.

Apoptosis is a highly conserved form of programmed cell death in organisms, playing a crucial role in various physiological and pathological processes such as embryonic development, tissue homeostasis maintenance, immune system regulation, and disease progression.

Tumor necrosis factor-α (TNF-α), as a key regulator of the immune system, is primarily secreted by activated macrophages and T lymphocytes

Interleukin-6 (IL-6) is a single-chain multifunctional cytokine composed of 212 amino acids, and its encoding gene is located on human chromosome 7.

Interleukin-7 (IL-7) is a pivotal cytokine in the immune system that regulates lymphocyte production, homeostasis, and survival. Unlike IL-2, which primarily activates effector functions, or IL-4, which drives specific differentiation, the core role of IL-7 lies in providing continuous survival signals for T cells and B cells, serving as the "fundamental life-support factor" for maintaining the size and diversity of the adaptive immune cell repertoire.

In the intricate immune defense network of the human body, the interferon family constitutes the first line of defense against pathogen invasion. Among them, IFN-α4, as a key member of type I interferons, serves as the most rapid and functionally potent "rapid response force" in the immune system. This article will delve into what IFN-α4/IFNA4 protein is and comprehensively explore its complex associations with various diseases and their clinical significance.

IL-7 is a soluble secreted protein encoded by the IL7 gene, with a molecular weight of approximately 25 kDa.

In the complex mechanism of resisting external invasion and maintaining internal environmental stability in the body, interleukin (IL) plays a key role as a "signal commander" as a core member of the cytokine family. These seemingly tiny protein molecules regulate the activation, proliferation, and differentiation of immune cells through precise signaling, maintaining the balance and efficiency of immune responses.

The interleukin-2 receptor alpha subunit (IL-2R alpha, also known as CD25) plays a crucial role in the precise regulatory network of the immune system. Since its discovery, IL-2R α has become a focal molecule for researchers to delve into immune regulation mechanisms, disease occurrence and development, and treatment strategies.
