Adrenal activity can be assessed in the equine species by analysis of feces for corticosterone metabolites. The method offers a non-invasive option to assess long term patterns in both domestic and free ranging horses. This protocol describes the enzyme linked immunoassay involved and the associated biochemical validation.

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
0 Views •
2024
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation. ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

2024
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2 (COX-2),...

We describe the procedure and data analysis of a chemical screening system for glucocorticoid stress hormone signaling using zebrafish larvae: the Glucocorticoid Responsive In vivo Zebrafish Luciferase activitY (GRIZLY) assay. The assay sensitively and specifically detects effects on glucocorticoid signaling by compounds that require metabolization or affect endogenous glucocorticoid production.

Functional Groups

Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...
FAQs
Once a glucocorticoid binds its intracellular receptor, the receptor-hormone complex moves into the nucleus and changes gene transcription. This provides a direct route from a circulating hormonal signal to altered cellular activity. The resulting transcriptional changes help coordinate metabolic adjustments with reduced inflammatory and immune activity, explaining how one signaling system can support several aspects of stress adaptation.
Metabolic effects help preserve glucose availability while also changing how protein and lipid resources are handled. This coordination matters because stress adaptation requires more than an immune response: cells must adjust the fuels and substrates available to the body. Studying these linked outcomes allows biologists to connect receptor-driven transcription with whole-organism metabolic balance during physiological stress.
Transient glucocorticoid activity can support homeostasis during physiological stress, whereas excessive or prolonged activity can disturb metabolic balance and immune regulation. This contrast is central to interpreting outcomes: the same broad regulatory capacity that helps the body adapt can become disruptive when its duration or magnitude exceeds the conditions associated with normal stress responses.
A basic analysis can follow the pathway from adrenal cortex production to receptor action, then examine changes in metabolism, inflammation, immune activity, and stress adaptation. This sequence separates the hormone's source, cellular mechanism, and physiological outcomes. It also helps compare normal homeostatic responses with disruption caused by excessive or prolonged activity.
It connects cellular signaling with organism-level regulation. In biology, the pathway illustrates how an intracellular receptor can translate a steroid signal into changes in gene transcription and physiological state. In endocrinology and stress physiology, it provides a framework for relating adrenal hormone activity to glucose availability, immune restraint, and maintenance or disruption of homeostasis.
Glucocorticoid function helps explain why corticosteroid drugs can be useful for controlling inflammation and immune activity. Their therapeutic relevance follows from the same receptor-mediated regulatory effects used in normal physiology. At the same time, the biology highlights an important limitation: excessive or prolonged glucocorticoid activity may disturb metabolic balance and immune regulation, making both benefit and physiological disruption relevant to therapy.
