interleukin 10 (IL10) Interleukin 10 (IL10) is an anti-inflammatory cytokine produced by a variety of immune cells, including T cells, B cells, macrophages, dendritic cells, and certain subsets of regulatory T cells. IL10 primarily functions to limit and terminate inflammatory responses by inhibiting the synthesis of pro-inflammatory cytokines such as IFN-γ, IL-2, IL-3, TNF-α, and GM-CSF produced by activated macrophages and helper T cells. It also suppresses antigen presentation by downregulating the expression of major histocompatibility complex (MHC) class II and co-stimulatory molecules on antigen-presenting cells. Through these mechanisms, IL10 plays a key role in maintaining immune homeostasis, preventing tissue damage during immune responses, and promoting the resolution of inflammation. IL10 is utilized as a biomarker to assess immune regulation and anti-inflammatory activity in various clinical and research contexts. Elevated IL10 levels in biological fluids such as serum, plasma, or cerebrospinal fluid have been associated with infectious diseases, autoimmune conditions, and certain cancers, reflecting the host's attempt to counteract excessive inflammation or immune activation. Measurement of IL10 concentrations can provide information about disease activity, immune response status, and the balance between pro- and anti-inflammatory signals in conditions such as sepsis, rheumatoid arthritis, inflammatory bowel disease, and viral infections.
interleukin 6 (IL6) Interleukin 6 (IL6) is a multifunctional cytokine produced by various cell types, including T cells, B cells, macrophages, fibroblasts, and endothelial cells. It plays a central role in the regulation of immune responses, inflammation, hematopoiesis, and the acute phase response. IL6 acts by binding to its receptor complex, which activates downstream signaling pathways such as JAK/STAT, MAPK, and PI3K/Akt. Its biological effects include stimulation of B cell differentiation, promotion of T cell proliferation, induction of hepatic acute phase protein synthesis, and modulation of metabolic, regenerative, and neural processes. IL6 is tightly regulated under physiological conditions, but dysregulation can contribute to chronic inflammation and various disease states. IL6 is measured in biological fluids, such as serum or plasma, as an indicator of inflammation and immune activation. Elevated IL6 levels have been associated with inflammatory and autoimmune disorders, infectious diseases, and certain malignancies. Clinically, IL6 concentrations are used to support the assessment of disease activity, monitor therapeutic response, and provide prognostic information in conditions such as rheumatoid arthritis, sepsis, COVID-19, and some cancers. Its utility as a biomarker is based on its established role in mediating and reflecting systemic inflammatory processes.
matrix metallopeptidase 13 (MMP13) Matrix metallopeptidase 13 (MMP13), also known as collagenase-3, is a member of the matrix metalloproteinase (MMP) family of zinc-dependent endopeptidases. MMP13 is primarily involved in the degradation of extracellular matrix components, with a strong substrate preference for type II collagen, but it can also cleave type I and III collagens and other matrix proteins. MMP13 plays a critical role in normal physiological processes such as embryonic development, bone remodeling, and tissue repair by facilitating extracellular matrix turnover. Its expression is tightly regulated under normal conditions and is typically low in most adult tissues. MMP13 has been investigated as a biomarker in several pathological conditions characterized by increased extracellular matrix remodeling. Elevated levels of MMP13 have been observed in diseases such as osteoarthritis, where it contributes to cartilage degradation, and in certain cancers, where it is associated with tumor invasion and metastasis. Measurement of MMP13 expression or activity in biological samples, such as synovial fluid or tissue biopsies, has been explored for its potential to reflect disease presence, progression, or response to therapy in these contexts.
matrix metallopeptidase 3 (MMP3) Matrix metallopeptidase 3 (MMP3), also known as stromelysin-1, is a member of the matrix metalloproteinase (MMP) family. MMP3 is a zinc-dependent endopeptidase that degrades components of the extracellular matrix (ECM), including fibronectin, laminin, collagens (types III, IV, IX, and X), and proteoglycans. In addition to its direct proteolytic activity, MMP3 can activate other MMPs, thereby amplifying matrix remodeling processes. MMP3 is involved in normal physiological processes such as tissue remodeling, wound healing, and embryonic development. It is also regulated by cytokines, growth factors, and mechanical stress, and its expression is tightly controlled to maintain tissue homeostasis. MMP3 has been investigated as a biomarker in various pathological conditions characterized by extracellular matrix remodeling and inflammation. Elevated levels of MMP3 in serum, synovial fluid, or tissue samples have been associated with diseases such as rheumatoid arthritis, osteoarthritis, and certain cancers. In these contexts, MMP3 measurements have been used in research settings to assess disease activity, monitor progression, and evaluate response to therapy. Its application as a biomarker is based on its involvement in tissue degradation and inflammation.
transforming growth factor beta 1 (TGFB1) Transforming growth factor beta 1 (TGFB1) is a multifunctional cytokine that belongs to the TGF-beta superfamily. It plays a central role in the regulation of cell growth, proliferation, differentiation, and apoptosis in various cell types. TGFB1 is involved in the control of immune responses, maintenance of tissue homeostasis, and modulation of extracellular matrix production. It exerts its effects primarily through binding to TGF-beta receptors, which activate intracellular SMAD signaling pathways. TGFB1 is also implicated in the regulation of inflammation, wound healing, and fibrosis by promoting the synthesis of extracellular matrix proteins and inhibiting the activity of matrix-degrading enzymes.

Elevated levels of TGFB1 in tissue, serum, or plasma have been associated with disease progression and severity in conditions such as liver fibrosis, pulmonary fibrosis, and certain malignancies. Its expression has also been measured to assess the extent of tissue remodeling and immune activation in various diseases. The quantification of TGFB1 can provide information relevant to disease status, prognosis, and response to therapy in research and clinical settings.
tumor necrosis factor (TNF) Tumor necrosis factor (TNF) is a pro-inflammatory cytokine primarily produced by activated macrophages, as well as by other immune and non-immune cells. TNF plays a central role in the regulation of immune responses, inflammation, apoptosis, and cell proliferation. It acts through binding to its receptors, TNFR1 and TNFR2, initiating signaling cascades that can lead to the activation of nuclear factor-kappa B (NF-κB), mitogen-activated protein kinases (MAPKs), and caspases. These pathways contribute to the modulation of immune cell activity, induction of fever, promotion of leukocyte recruitment, and mediation of programmed cell death. TNF is involved in host defense mechanisms against infections and tumor cells, but excessive or dysregulated TNF production is associated with the pathogenesis of various inflammatory and autoimmune diseases. TNF is measured as a biomarker in clinical and research settings to assess the presence and extent of inflammation. Elevated levels of TNF in blood, tissue, or other biological fluids have been associated with inflammatory and autoimmune conditions such as rheumatoid arthritis, inflammatory bowel disease, sepsis, and certain cancers.
