생화학적/생리학적 작용

Interleukin-1 (IL-1), originally known as Lymphocyte Activating Factor (LAF), activates T cell lymphocytes, which then proliferate and secrete interleukin-2 (IL-2). IL-1 is released primarily from stimulated macrophages and monocytes, but has also been shown to be released from several other types and is thought to play a key role in inflammatory and immune responses. Other synonyms for IL-1 include: endogenous pyrogen (EP), mitogenic protein (MP), Helper Peak-1 (HP-1), T Cell Replacing Factor III (TRF III or TRFM), B Cell Activating Factor (BAF) and B Cell Differentiation Factor (BDF) The two closely related agents Interleukin-1α (IL-1α) and Interleukin-1β (IL-1β) share 62% homology in amino acid sequence and elicit nearly identical biological responses. IL-1α and IL-1β are both approximately 17 kDa with some heterogeneity in the amount of glycosylation.

물리적 형태

Lyophilized from a 0.2 μm filtered buffered solution.

분석 메모

Complex interactions exist between cytokines, and the interleukin family plays a fundamental role in inflammation. Particularly circulating IL-1β, IL-6 and IL-8 are unregulated in systemic and chronic inflammatory conditions. Hypercoagulability is an important hallmark of inflammation, and these cytokines are

Though Illumina has largely dominated the RNA-Seq field, the simultaneous availability of Ion Torrent has left scientists wondering which platform is most effective for differential gene expression (DGE) analysis. Previous investigations of this question have typically used reference samples derived

The environment surrounding chondrocytes changes drastically in osteoarthritis (OA). For instance, the osmolarity in cartilage (ranging from 350 to 460 mOsm in healthy tissue) decreases during the progression of OA, reaching 270 mOsm. The objective of this study was to

In pancreatic islets, free radical formation produced upon exposure to proinflammatory cytokines mediates β cell destruction, which ultimately leads to type 1 diabetes (T1D). In this study, we examined whether laccase, a family of the blue copper protein, can be

Microsomal PGE synthase-1 (mPGES-1), the inducible synthase that catalyses the terminal step in PGE2 biosynthesis, is of high interest as therapeutic target to treat inflammation. Inhibition of mPGES-1 is suggested to be safer than traditional NSAIDs, and recent data demonstrate
