Cat.No.S3968

Histamine, an organic nitrogenous compound, is involved in local immune responses regulating physiological function in the gut and acting as a neurotransmitter for the brain, spinal cord, and uterus. It is a potent H1 and H2 receptor agonist. This compound can be used to induce animal models of Gastric and Intestinal Ulcers.

Mechanism of Action

In vitro	Histamine stimulates the proliferation of human articular chondrocytes in culture. This compound is reported to modify the behaviour of many cell types in vitro, including chondrocytes, fibroblasts, macrophages, epithelial cells, endothelial cells, and T cells. It also modulates the production of many cytokines and the expression of their receptors. This chemical regulates cellular processes through the expression of its receptors. It stimulates the production of matrix metalloproteinases (MMPs)-13 and -3 (collagenase 3 and stromelysin-1, respectively) by histidine decarboxylase (HAC) in vitro.
In vivo	Histamine has a recognised role in allergic and inflammatory reactions and is an important modulator of numerous physiological processes, including cell proliferation, angiogenesis, and vasopermeability. This compound dilates vasculature, increases blood flow, while it induces hyperpermeability in venula. It disrupts endothelial barrier formation of venula indicated by changes in vascular endothelial cadherin (VE-cadherin) localization at endothelial cell junction.
