Parishin E
Based on 1 Customer Validation
Parishin E is a modulator of hexokinase 2, lactate dehydrogenase A, and silent information regulator 6 (sirtuin 6), and is also a component present in Gastrodia elata Blume. Parishin E reduces the expression of hexokinase 2 and lactate dehydrogenase A, thereby regulating the process of cellular glycolysis. Parishin E regulates the deacetylation mediated by silent information regulator 6 (Sirtuin 6), and inhibits histone 3 lactylation modifications at the H3K18la and H3K27la sites. Parishin E inhibits macrophage polarization. Parishin E alleviates LPS-induced inflammatory responses and suppresses the expression of pro-inflammatory cytokines. Parishin E exerts ameliorating effects on rheumatoid arthritis. Parishin E can be used in studies related to rheumatoid arthritis.

RNA extraction experimental
By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.

Collagen-Induced Arthritis
Collagen-induced arthritis (CIA) is an autoimmune murine model of rheumatoid arthritis in which immunization with type II collagen (CII) emulsified in an adjuvant induces a T cell- and autoantibody-driven inflammatory arthritis characterized by synovial hyperplasia, immune cell infiltration, and joint destruction. The model typically relies on genetically susceptible mouse strains (e. g. , DBA/1) and reproduces key features of human rheumatoid arthritis, including anti-collagen immune responses and progressive joint inflammation. Disease onset generally occurs within ~3-4 weeks after immunization, depending on antigen/adjuvant combinations and protocol variation. The immunopathology is driven by adaptive immune activation against CII, leading to systemic and local joint inflammation mediated by pro-inflammatory cytokines and effector immune cells, making CIA a standard preclinical platform for evaluating immunomodulatory and anti-arthritic interventions.

LPS-Induced Endotoxemia/Systemic Inflammation
Lipopolysaccharide (LPS)-induced endotoxemia is a widely used in vivo model of acute systemic inflammation in which LPS, a Gram-negative bacterial endotoxin, activates innate immune signaling primarily through TLR4, leading to rapid and transient induction of pro-inflammatory cytokines such as TNF-α, IL-6, and IL-1β in circulation and tissues. This cytokine surge is commonly used as a measurable readout of systemic inflammatory activation and immune dysregulation, and is typically assessed within hours after intraperitoneal LPS administration in mouse models of endotoxemia. The model captures key features of systemic inflammatory response syndrome, including cytokine release, immune cell activation, and downstream tissue responses, and has been used to evaluate anti-inflammatory interventions such as cytokine modulation, lipid mediators, and immune cell-targeting therapies.

Primary monocyte-to-macrophage differentiation
Primary human monocytes can be differentiated ex vivo into monocyte-derived macrophages by culturing purified blood monocytes for approximately 5-7 days in macrophage-supporting cytokine conditions; M-CSF commonly yields CD14^high/CD163^high macrophages, while GM-CSF yields a phenotypically distinct macrophage population, so the cytokine condition should be chosen according to the downstream model. The readout of successful differentiation is a combined change in morphology, adherence, surface phenotype, and function: differentiated macrophages become adherent, enlarge, acquire macrophage-associated markers such as CD14, CD68, CD163, CD206, or HLA-DR depending on culture condition, and show increased phagocytic capacity compared with starting monocytes.

Research Protocol for Inflammation-related Diseases
The NLRP3 inflammasome is a cytosolic innate immune signaling platform that integrates priming signals and danger-signal activation to promote caspase-1 activation, maturation of IL-1β and IL-18, and gasdermin D-mediated pyroptotic cell death. The core experimental logic is to determine whether inflammatory disease phenotypes are driven by increased NLRP3 expression, ASC-containing inflammasome assembly, caspase-1 cleavage, GSDMD cleavage, and extracellular release of IL-1β/IL-18 rather than by nonspecific cell injury alone. The pathway is strongly linked to inflammation-related disease phenotypes because monosodium urate crystals activate NALP3/NLRP3 inflammasome signaling in gout-like crystal inflammation, cholesterol crystals activate NLRP3 inflammasomes in atherogenesis models, and DSS-induced intestinal inflammation has been reported to involve NLRP3 inflammasome activity. However, experimental colitis studies also show context-dependent protective effects of NLRP3 inflammasome co
