p140 peptide peptide - Lupuzorpeptide P140 Peptide

P140 peptidefor sale online The p140 peptide represents a novel therapeutic approach targeting autoimmune and inflammatory diseases by modulating the immune system. Derived from the spliceosomal protein U1-70K and specifically phosphorylated at the serine 140 position, this synthetic peptide, also known as Forigerimod or Lupuzor™, shows promise in restoring immune homeostasis.Thepeptideis used to block Anti-p140Cap Antibody reactivity. Applications Tested/Suitable for SRCIN1 blockingpeptide. Blocking (BL). TOP. Sample Manual ... Research indicates that the p140 peptide acts by depleting hyper-activated autoreactive T and B cells, thereby offering a potential treatment for conditions like systemic lupus erythematosus (SLE).

Understanding the Mechanism of Action

The therapeutic effect of the p140 peptide is attributed to its ability to interact with key components of the immune responseP140(Lupuzor™, forigerimod) is a first-in-classpeptide-based therapy designed to address the root cause of autoimmune and inflammatory diseases.. It binds to the chaperone protein HSPA8/HSC70, which is crucial for presenting antigens. This interaction appears to induce apoptosis, or programmed cell death, in activated autoreactive T cells, particularly CD4+ T cells.作者：N Schall·2022·被引用次数：10—Data indicate thatP140acts by depleting hyper-activated autoreactive T and B cells and restores normal immune homeostasis. Furthermore, studies suggest that the p140 peptide can decrease autoepitope recognition by T cells and down-regulate the overexpression of HLA class II molecules on lupus B cells. By targeting these overactive immune cells and molecules, the p140 peptide aims to reset the autoreactive immune system without causing broad immunosuppression, a significant advantage in treating chronic autoimmune conditions.

Clinical Applications and Research

The primary focus of p140 peptide research has been its application in systemic lupus erythematosus (SLE). Clinical trials, including randomized, double-blind, placebo-controlled studies, have investigated the safety, tolerability, and efficacy of p140 peptide (Lupuzor™) in lupus patients. These trials have shown that the peptide can be efficacious and is generally well-tolerated, with longer treatment periods potentially increasing the number of responders. Beyond SLE, the p140 peptide's immunomodulatory properties suggest potential applications in other autoimmune and inflammatory diseases, although research in these areas is less advanced. The peptide's ability to influence the autophagic flux in antigen-presenting cells (APCs) and destabilize MHC class II molecules further underscores its complex and multifaceted mechanism of action in immune regulation.

The p140 Peptide and Immune Homeostasis

Restoring immune homeostasis is a central goal in treating autoimmune diseases.Spliceosomal peptide P140 for immunotherapy of systemic ... The p140 peptide achieves this by selectively targeting and eliminating the specific immune cells that are causing the autoimmune attack. Unlike conventional immunosuppressive therapies that broadly dampen the immune system, potentially increasing susceptibility to infections, the p140 peptide offers a more targeted approach. By depleting hyper-activated autoreactive lymphocytes and normalizing the immune response, it aims to return the immune system to a balanced state. This precise modulation is critical for managing chronic conditions where the immune system mistakenly attacks the body's own tissues.The aim of this study was to investigate the effect ofpeptide P140on the inflammatory responses in crystal-induced mouse models of gout and cell models.

Future Directions and Considerations

While promising, the development and application of the p140 peptide are ongoing.P140is a syntheticpeptideissued from the U1-70K protein. It was chemically modified and contains a phosphoserine residue at position 140. Further research is needed to fully elucidate its long-term effects, optimize dosing regimens, and explore its efficacy in a wider range of autoimmune conditions.P140is a 21-mer linearpeptide(sequence 131-151) that is derived from the small nuclear ribonucleoprotein U1-70K and that is phosphorylated at the Ser140position. In a multicenter, randomized, placebo-controlled phase IIb study, Lupuzor was safe and met its primary efficacy end points in lupus patients (Zimmer et al ... The binding of the p140 peptide to HSC70 also opens avenues for investigating its role in other cellular processes, such as chaperone-mediated autophagy.P140(Lupuzor™, forigerimod) is a first-in-classpeptide-based therapy designed to address the root cause of autoimmune and inflammatory diseases. As research progresses, the p140 peptide has the potential to become a significant therapeutic tool for individuals suffering from debilitating autoimmune diseases, offering a new strategy for immune system regulation and disease management.
