    • Introduction

      Tumor necrosis factor is a cytokine involved in systemic inflammation and is a member of a group of cytokines that all stimulate the acute phase reaction. TNF is mainly secreted by macrophages.
      TNF causes apoptotic cell death, cellular proliferation, differentiation, inflammation, tumorigenesis and viral replication, TNF is also involved in lipid metabolism, and coagulation. TNF's primary role is in the regulation of immune cells.
      Dysregulation and, in particular, overproduction of TNF have been implicated in a variety of human diseases- autoimmune diseases, insulin resistance, and cancer.

    • Synonyms

      TNF-alpha, Tumor necrosis factor ligand superfamily member 2, TNF-a, Cachectin, DIF, TNFA, TNFSF2.

    • Background

      Tumor Necrosis Factor-alpha (TNF-α) is a pro-inflammatory cytokine that plays a critical role in the regulation of immune responses, inflammation, and cell survival. It is primarily produced by activated macrophages, but can also be secreted by other immune cells, such as T cells, natural killer cells, and mast cells. TNF-α is involved in a wide range of physiological and pathological processes, including the defense against infections, the development of autoimmune diseases, and the progression of cancer.

      TNF-α exerts its effects by binding to two distinct cell surface receptors, TNF receptor 1 (TNFR1) and TNF receptor 2 (TNFR2). Upon binding to its receptors, TNF-α activates multiple signaling pathways, including the nuclear factor-kappa B (NF-κB) pathway, the mitogen-activated protein kinase (MAPK) pathway, and the apoptotic pathway. These signaling pathways regulate various cellular processes, such as inflammation, cell proliferation, differentiation, and apoptosis.

      In the context of infections, TNF-α plays a crucial role in the body's defense against pathogens. It promotes the recruitment and activation of immune cells, enhances the production of other pro-inflammatory cytokines, and stimulates the expression of adhesion molecules on endothelial cells, facilitating the migration of immune cells to the site of infection. TNF-α also helps to induce fever, which is an important component of the body's immune response to infections.

      However, excessive or prolonged production of TNF-α can contribute to the development of chronic inflammatory diseases, such as rheumatoid arthritis, inflammatory bowel disease, and psoriasis. In these conditions, elevated levels of TNF-α promote the infiltration of immune cells into the affected tissues, leading to tissue damage and the perpetuation of inflammation. The central role of TNF-α in the pathogenesis of these diseases has led to the development of anti-TNF-α therapies, which have revolutionized the treatment of chronic inflammatory diseases. These therapies include monoclonal antibodies, such as infliximab and adalimumab, and soluble TNF receptor fusion proteins, such as etanercept. Anti-TNF-α therapies have been shown to be effective in reducing inflammation, improving symptoms, and slowing disease progression in patients with chronic inflammatory diseases.

      In the context of cancer, TNF-α has complex and context-dependent effects on tumor development and progression. On one hand, TNF-α can promote anti-tumor immunity by activating immune cells and stimulating the production of other pro-inflammatory cytokines. On the other hand, chronic inflammation driven by TNF-α can promote tumor growth, angiogenesis, and metastasis. Therefore, the role of TNF-α in cancer is still an area of active research, and the development of TNF-α-targeted therapies for cancer remains a challenge.

      In conclusion, TNF-α is a pro-inflammatory cytokine that plays a critical role in the regulation of immune responses, inflammation, and cell survival. Its involvement in various physiological and pathological processes has made it an important target for the development of therapies for chronic inflammatory diseases and cancer. Anti-TNF-α therapies have revolutionized the treatment of chronic inflammatory diseases, but the complex role of TNF-α in cancer remains an area of ongoing research. Understanding the precise mechanisms by which TNF-α contributes to disease pathogenesis will be crucial for the development of more effective and targeted therapies.

    More Info

    • Introduction

      SELPLG glycoprotein functions as a high affinity counter-receptor for the cell adhesion selectin molecules (P, E and L) located in stimulated T lymphocytes and myeloid cells. SELPLG binds leukocytes to activated platelets or endothelia expressing selectins, a vital role in leukocyte trafficking throughout inflammation. In order to have a high-affinity binding activity SELPLG needs two post-translational modifications, tyrosine sulfation and the addition of the sialyl Lewis x tetrasaccharide (sLex) to its O-linked glycans. Polymorphisms and abnormal expression of SELPLG are linked to defects in the innate and adaptive immune response. Alternate splicing results in multiple transcript variants.

    • Introduction

      Interleukin-1 ra is a member of the interleukin 1 cytokine family. This protein inhibits the activities of interleukin 1, alpha (IL1A) and interleukin 1, beta (IL1B), and modulates a variety of interleukin 1 related immune and inflammatory responses.

    • Introduction

      Galectin-4 is a member of the subfamily of galectins composed of two carbohydrate recognition domains having similar peptide chains. The galectins are a family of beta-galactoside-binding proteins having a role in modulating cell-cell and cell-matrix interactions, which inhibits chronic inflammations, GVHD, and allergic responses. LGALS4 expression is limited to small intestine, colon, and rectum, and it is underexpressed in colorectal cancer. LGALS4 binds as an endogenous ligand to glycosphingolipids having 3-O-sulfated Gal residues and bind as well to cholesterol-3-sulfate. LGALS4 takes part in cell adhesion. LGALS4 plays a role in crosslinking the lateral cell membranes of the surface-lining epithelial cells, thus supporting epithelial integrity against mechanical stress exerted by the bowel lume. LGALS4 is in charge of intestinal inflammation via selective regulation of peripheral and mucosal T-cell cell cycle, in addition to cell death by apoptosis of T-cells by a pathway independent of the activation of caspases. LGALS4 blockade decreases TNF-alpha inhibitor induced T-cell death. LGALS4 decreases pro-inflammatory cytokine secretion including IL-6 & IL-17.

    • Introduction

      Leukocyte-associated immunoglobulin-like receptor 2 (LAIR2) is a secreted, 131 amino acids protein which contains one IglikeC2 type domain, rendering it a member of the Ig superfamily. Even though one is secreted and one is membrane bound, the 2 LAIR proteins are assumed to have evolved from a common gene ancestor and seem to share similar adhesion profiles, suggesting that LAIR2 may compete with LAIR1 for ligand binding. LAIR2 was discovered by its similarity to LAIR1, which is an inhibitory receptor present on mononuclear leukocytes. The LAIR2 gene maps to a region of 19q13.4, dubbed the leukocyte receptor cluster, which contains 29 genes in the immunoglobulin superfamily, including LAIR1. The function of the LAIR2 protein is unknown, though it is assumed to be secreted and may help modulate mucosal tolerance.

    • Background

      Leptin is mainly produced by adipocytes. Leptin’s main part is to regulate long-term energy balance. Leptin is encoded by the LEP gene. Leptin effects mostly on leptin receptors in the cell mambrane of various cells in the human body. The leptin receptor can be found on a various cell types. The leptin receptor is a single-transmembrane-domain type 1 cytokine receptor. leptin levels influence satiety, appetite and triggers behaviours which save energy. High leptin levels are interpreted by the brain that energy reserves are high, whereas low leptin levels means that energy reserves are low, in the process adapting the organism to starvation through a variety of metabolic, neurobiochemical, endocrine and behavioral change.

    Escherichia coli.

    Formulation

    The Mouse Leptin triple anatagonist was lyophilized from a concentrated (0.65mg/ml) solution with 0.003mM NaHCO3.

    Purity

    Greater than 99.0% as determined by:
    (a) Gel filtration analysis.
    (b) Analysis by SDS-PAGE.

    Biological Activity

    Leptin Antagonist Triple Mutant Mouse Recombinant half-life in circulation after SC injection was over 20 hours.
    Leptin Antagonist Triple Mutant Mouse Recombinant is capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Leptin Antagonist Triple Mutant Mouse Recombinant in vitro activity is 5-6 fold lower than the non-pegylated antagonist, though in vivo it has profound weight gain effect (as compared to the non-pegylated antagonist), resulting mainly from increased food intake.

    • Physical Appearance

      White lyophilized (freeze-dried) powder.

    • Stability

      Lyophilized Leptin Antagonist Triple Mutant Mouse Recombinant although stable at room temperature for several weeks, should be stored desiccated below -18°C. Upon reconstitution at > 0.1 Leptin mutant mg/ml and up to 2mM and filter sterilization LEP mutant can be stored at 4°C or even room temperature for several weeks making it suitable for long term infusion studies using osmotic pumps. At lower concentration addition of a carrier protein (0.1% HSA or BSA) is suggested.Please prevent freeze-thaw cycles.

    • Solubility

      It is recommended to reconstitute the lyophilized Leptin Antagonist Triple Mutant Mouse Recombinant in sterile water or sterile 0.4% NaHCO3 adjusted to pH 8-9, not less than 100µg/ml, which can then be further diluted with other aqueous solutions.

    • Protein content

      Protein quantization was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.2 as the extinction coefficient for a 0.1% (1mg/ml) solution at pH 8.0. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).

    • Introduction

      Ubiquitin-conjugating enzyme E2 H (UBE2H) is a member of the ubiquitin-conjugating enzyme family. Protein modification with ubiquitin is a vital cellular apparatus for directing abnormal or short-lived proteins for degradation. Ubiquitination requires at least 3 classes of enzymes: ubiquitin-activating enzymes (E1s) ubiquitin-conjugating enzymes (E2s) and ubiquitin-protein ligases (E3s). UBE2H receives ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. UBE2H protein sequence is 100% identical to the mouse homolog and 98% identical to the frog and zebrafish homologs.

    • Synonyms

      Ubiquitin-conjugating enzyme E2 H, UbcH2, Ubiquitin carrier protein H, Ubiquitin-conjugating enzyme E2-20K, Ubiquitin-protein ligase H, UBE2H, GID3, UBC8, UBCH.

    • Physical Appearance

      Sterile filtered colorless solution.

    • Stability

      Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.
