Fluvastatin inhibits mast cell degranulation without changing the cytoplasmic Ca2+ level. 2009

The statin-induced inhibitory action may be mediated by the suppression of geranylgeranyl transferase via the depletion of intracellular mevalonic acid.

To clarify how hypothalamic neuronal histamine regulates peripheral energy expenditure, we investigated the effect of infusion of histamine into the third cerebral ventricle or discrete hypothalamic regions on sympathetic nerve activity and expression of uncoupling protein 1 (UCP1) mRNA in brown adipose tissue (BAT). Infusion of histamine (200 nmol) into the third cerebral ventricle of anesthetized rats significantly increased the electrophysiological activity of sympathetic nerves (P<0.01) and UCP1 mRNA expression in the BAT (P<0.05). Microinjection of histamine (10 nmol) into the paraventricular nucleus (PVN) and preoptic area (POA) produced similar significant increases in BAT sympathetic nerve activity (P<0.01 for each). By contrast, injection of histamine into the ventromedial hypothalamic nucleus or lateral hypothalamic area had no effect. We conclude that hypothalamic neuronal histamine may regulate energy expenditure in BAT through the activation of sympathetic nerves. The PVN and/or POA appear to be the principal hypothalamic sites that mediate the stimulatory effect of histamine on this efferent pathway.

Abstract
Mast cells play an essential role in diverse physiological and pathological processes, such as atherosclerosis, malignancy, asthma, pulmonary fibrosis and arthritis, directly interact with bacteria, and appear to play a vital role in host defense against pathogens. Mast cells could be recruited in the inflammatory site, by MCP-1, RANTES and SCF, to selectively secrete proinflammatory molecules; these could include growth factors, histamine, which is mitogenic (H1) and an immunosuppressant (H2), neovascularization agents, such as heparin, IL-8, and VEGF, as well as proteases that could permit new blood vessel formation. Neurogenic inflammation involves vasodilation and plasma protein extravasation in response to neural stimulation. Upon stimulation, sensory neurons release Substance P and other neuropeptides and activate neurokinin-1 receptors leading to plasma protein extravasation from post-capillary venules. Substance P is a neuropeptide that is released from nerve endings in many tissues and plays an important role in immunological and inflammatory states, and it is also a mediator of tissue injury, asthma, arthritis, allergy and autoimmune diseases. SP-positive nerve fibers and mast cell contacts are increased by acute stress in mice leading to dermal mast cell degranulation. VEGF is produced by flammatory cells. IL-33 is the newest inflammatory member of the IL-1 cytokine family and we show here that SP can induce VEGF secretion from mast cells and IL-33 augments the effect of SP in VEGF transcription and translation protein.

Anxiety Histamine

The results suggest that histamine may modulate anxiety via H1 but not H2 receptors in the rat central amygdala.
