Within the brain, the inflammatory cytokine interleukin-1 (IL-1) mediates illnessassociated neural, neuroendocrine, and behavioral responses; however, its role in normal neurobehavioral processes is not clear. To examine the role of IL-1 signaling in memory, we infused Long–Evans rats intracerebroventricularly with IL-1b (10 ng/rat), IL-1 receptor antagonist (IL-1ra, 100 mg/rat), or saline imme...

The effects of caerulin, a CCK receptor agonist, and proglumide, a receptor antagonist, on hyperalgesia induced by sciatic nerve ligation, was studied in mice. Tolerance to the morphine response was obtained 3,7, 14,21 and 28 days after unilateral sciatic nerve ligation. Maximum hyperalgesia was found 14 days after nerve ligation. Caerulin increased morphine antinociception in nerve-ligated ani...

We have examined the binding of human and rodent interleukin-1 receptor antagonist (IL-1ra) to the type II IL-1 receptor on the human B cell line, Raji, on the mouse pre-B cell line, 70Z/3, and on human polymorphonuclear leukocytes (PMNs). Human IL-1ra binds to the receptors on the human B cells with an affinity (KD = 15 +/- 3 nM) equal to that of IL-1 alpha and only 15-fold lower than that of ...

Chemotherapy has remained the mainstay for treatment of multiple types cancers. In particular, topical use chemotherapy been used skin Though effective, limited due to adverse effects such as local and even systemic toxicities. Given our ongoing studies that exposure pro-oxidative stressors, including therapeutic agents induces generation extracellular vesicles known microvesicle particles (MVP...

The role of the angiotensin type 2 (AT(2)) receptor in the pathogenesis of progressive renal injury has not been previously elucidated. The renal expression of the AT(1) and AT(2) receptors in subtotally nephrectomized rats (STNx) and the effects of AT(2) receptor blockade on renal injury were explored. Reduced renal expression of the AT(1) but not the AT(2) receptor was observed in STNx by rev...

A functionalized derivative of the alpha 2-selective antagonist rauwolscine formed the basis for a photoaffinity adduct that has allowed identification of the hormone-binding subunit of the brain alpha 2-adrenergic receptor protein. Rauwolscine carboxylate underwent reaction with 4-N-t-butyloxycarbonyl-aminoaniline, leading to the synthesis of rauwolscine 4-aminophenyl carboxamide (Rau-AmPC). R...

Regular moderate exercise has been shown to have anti-inflammatory effects that help prevent several chronic diseases. However, the effects of chronic training an elite athletes have not been the focus of much research. This study aimed to determine whether there were differences in cytokine levels (IL-1 β , IL-1ra, IL-6, IL-10, IL-18, IFN- γ , and TNF- α ) in circulating peripheral blood (PB) ...

PURPOSE There is now extensive evidence to support the involvement of inflammation in the course of epileptic seizures. Seizure-induced changes in serum IL-1β, IL-6 and IL-1Ra levels are reported in several studies. Serum cytokine levels may also be disturbed in inter-ictal period due to seizure activity. METHODS Twenty-one patients (12 women; mean age 35±12.3) with temporal lobe epilepsy (TL...
