HIF-1α regulates IL-1β and IL-17 in sarcoidosis

Tumorigenicity of IL-1α– and IL-1β–Deficient Fibrosarcoma Cells

Analyzing the growth of fibrosarcoma lines derived from IL-1α–, IL-1β–, or IL-1αβ–knockout () mice in the immunocompetent host revealed that tumor-derived IL-1α and IL-1β exert strong and opposing effects on immune response induction, which prohibited the evaluation of a potential impact on tumorigenicity. Therefore, in vivo growth of IL-1–deficient tumor lines was evaluated in nu/nu mice and w...

Cytokines (IL-17, IL-23, and IL-33) in Systemic lupus erythematosus in Trinidad and Tobago.

Systemic lupus erythematosus (SLE) is the most common autoimmune disease. It is characterized by the presence of hundreds of autoantibodies against many organs and tissues, including the presence of a large number of autoantibodies, which are specific to self-antigens mainly of nuclear origin such as Smith antigen, double-stranded DNA (dsDNA), anti-Sjögren’s syndrome-related antigen A and B (SS...

IL-1α and IL-1β-producing macrophages populate lung tumor lesions in mice

Macrophages highly populate tumour microenvironment and are referred to as tumor-associated macrophages (TAMs). The inflammasome is a multiprotein complex responsible of IL-1 like cytokines release, which biology has been widely studied by using bone-marrow-derived macrophages to mimic a physiological and/or host defense condition. To understand the role of this complex in lung tumor-associated...

Unique Versus Redundant Functions of IL-1α and IL-1β in the Tumor Microenvironment

Interleukin-1 (IL-1) is a major "alarm" upstream pro-inflammatory cytokine that also affects immunity and hematopoiesis by inducing cytokine cascades. In the tumor arena, IL-1 is produced by malignant or microenvironmental cells. As a pleiotropic cytokine, IL-1 is involved in tumorigenesis and tumor invasiveness but also in the control of anti-tumor immunity. IL-1α and IL-1β are the major agoni...
