Biological Activity
Description
In Vitro
Flunisolide (0.1-10 μM, 1 h) inhibits lung fibroblast (Isolated from lung) activation[1]. Flunisolide (10 μM, 24 h) reduces MMP-9, TIMP-1, TGF-β and fibronectin release by sputum cells (isolated from mild to moderate asthmatics), and induces sputum eosinophil apoptosis[2]. Flunisolide (0.1-10 μM μM, 24 h) effectively inhibits ICAM-1 expression and GM-CSF and IL-5 release induced by TNF-alpha in BEAS-2B cells[3]. Flunisolide (115 μM, 0-3 h) can be transported in a polarized way in the apical (ap) to basolateral (bl) direction in Calu-3 cells and is demonstrated to be ATP-dependent[4].

Apoptosis
Apoptosis, also called programmed cell death, is generally characterized by distinct morphological characteristics.

TUNEL staining for apoptotic DNA fragmentation
TUNEL staining detects DNA strand breaks by using terminal deoxynucleotidyl transferase to add labeled nucleotides to exposed 3′-OH DNA termini, generating either microscopic staining in fixed cells or tissue sections, or fluorescence/cytometric signal in cell suspensions. TUNEL positivity reflects DNA fragmentation but should not be interpreted alone as definitive apoptosis, because TUNEL can also label necrotic, autolytic, mechanically damaged, or DNA-repair-associated DNA breaks.

Annexin V plus membrane-impermeant dye apoptosis staining
Annexin V-based apoptosis assays rely on the detection of phosphatidylserine (PS) externalization from the inner leaflet of the plasma membrane to the outer leaflet, an early biochemical hallmark of apoptosis. Fluorescently labeled Annexin V binds PS in a calcium-dependent manner, enabling identification of early apoptotic cells by flow cytometry or fluorescence microscopy. When combined with a membrane-impermeant DNA-binding dye (e. g. , propidium iodide), this approach allows discrimination between viable (Annexin V−/dye−), early apoptotic (Annexin V+/dye−), and late apoptotic or necrotic (Annexin V+/dye+) cell populations by assessing membrane integrity and PS exposure.

Cotton Pellet Granuloma
Cotton pellet granuloma is a classical in vivo chronic inflammation model used to evaluate the anti-inflammatory potential of test substances by measuring their ability to inhibit granuloma tissue formation around an implanted foreign body (cotton pellet) in rodents. The method is based on the biological response to a sterile implanted material, which induces proliferative phase inflammation characterized by fibroblast proliferation and collagen-rich granuloma formation, and the final readout reflects the extent of chronic inflammatory tissue growth surrounding the pellet. In multiple preclinical pharmacological evaluations, inhibition of cotton pellet-induced granuloma formation has been used as an indicator of anti-inflammatory activity in both synthetic and natural product screening contexts.

Research Protocol for Endocrine Diseases
Endocrine diseases often arise from disrupted hormone production, hormone signaling, or target-tissue responsiveness; for diabetes-focused endocrine disease models, insulin signaling regulates glucose uptake, hepatic glucose output, lipid metabolism, and β-cell compensation. Type 2 diabetes develops through interacting defects in insulin resistance, β-cell dysfunction, adipose inflammation, hepatic glucose overproduction, altered incretin signaling, and ectopic lipid metabolism. A major unresolved question is whether endocrine dysfunction is driven primarily by target-tissue insulin resistance, intrinsic β-cell failure, immune/inflammatory stress, or combined multi-organ failure that differs by disease stage.

Carrageenan-Induced Paw Edema
Carrageenan-induced paw edema is an acute inflammation model in which intraplantar injection of carrageenan induces localized inflammatory swelling characterized by vascular permeability, leukocyte infiltration, and production of inflammatory mediators such as prostaglandins and cytokines, making it widely used to evaluate anti-inflammatory agents in vivo. The resulting paw volume or thickness increase is quantified over time as a direct readout of inflammatory intensity and drug efficacy, typically reflecting cyclooxygenase-mediated prostaglandin-driven edema formation and immune cell recruitment in peripheral tissue[20].

Apoptosis Solutions
Apoptosis is a regulated, generally non-lytic cell-death pathway that removes unwanted, damaged, infected, or abnormal cells through coordinated morphological changes, caspase activation, DNA fragmentation, and membrane remodeling. The intrinsic apoptosis pathway is controlled mainly by mitochondrial outer membrane permeabilization, BCL-2 family proteins, cytochrome c release, apoptosome formation, caspase-9 activation, and downstream executioner caspase-3/7 activation. The extrinsic apoptosis pathway is initiated by death receptors such as Fas, TNFR, and TRAIL receptors, which recruit adaptor proteins and activate caspase-8 before engaging executioner caspases or mitochondrial amplification through BID cleavage. Apoptosis is linked to many phenotypes, including cancer cell killing, tissue homeostasis, immune regulation, neurodegeneration, infection response, and treatment-induced cytotoxicity; unresolved questions include how apoptosis interacts with necroptosis, pyroptosis, ferroptos

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
