Plumieride, an iridoid glucoside isolated from Plumieria acutifolia leaves was investigated for its immunostimulatory activity on humoral, cell mediated and intracellular cytokine levels in sensitized and unsensitised balb/c mice. Plumieride restores the suppressed cell mediated, humoral immune response and also enhances the release of TNF- α, IFN-γ, and IL-2 (Th-1) in immune compromised cyclosporine and cyclophosphamide treated balb/c mice. It does not stimulate the IL-4 (Th-2) expression. Plumieride demonstrates significant augmentation of Th-1 response in immunosuppressed balb/c mice...

Traumatic spinal cord injury (SCI) is a major challenge in the clinic. In this study, we sought to examine the synergistic effects of linear ordered collagen scaffold (LOCS) and human placenta-derived mesenchymal stem cells (hPMSCs) when transplanted into completely transected beagle dogs. After 36 weeks observation, we found that LOCS+hPMSCs implants promoted better hindlimb locomotor recovery than was observed in the non-treatment (control) group and LOCS group. Histological analysis showed that the regenerated tissue after treatment was well integrated with the host tissue, and dramatically reduced the volume of cystic and chondroitin sulfate proteoglycans (CSPGs) expression...

Inactivating mutations in the thyroid hormone (TH) transporter Monocarboxylate transporter 8 (MCT8) cause severe psychomotor retardation in children. Animal models do not reflect the biology of the human disease. Using patient-specific induced pluripotent stem cells (iPSCs), we generated MCT8-deficient neural cells that showed normal TH-dependent neuronal properties and maturation. However, the blood-brain barrier (BBB) controls TH entry into the brain, and reduced TH availability to neural cells could instead underlie the diseased phenotype...

BACKGROUND: Abnormal thyroid hormone (TH) metabolism is significantly associated with impaired left ventricular (LV) function and death. Although TH was traditionally thought to be produced exclusively by the thyroid gland, an increasing number of studies report TH production in other tissues. Based on these findings, we evaluated whether the genes required for TH biosynthesis are expressed in the human heart, and whether their expression is altered in patients with ischemic cardiomyopathy (ICM) and is related to epigenetic variations...

Oxidative stress plays an important role in both the initiation and progression of Parkinson's disease (PD). Rotenone, an environmental toxin, induces oxidative stress and impact mitochondrial dynamics, including fission and fusion. Thymoquinone (TQ) has been reported to have antioxidant and anti-inflammatory characteristics in vitro and in vivo. TQ scavenges free radicals so prevents cell damage against oxidative agents. To evaluate the efficacy of TQ in the management of PD, male Wistar rats (8-10 months) received rotenone...

OBJECTIVES: A citrulline (CIT)-enriched diet improves locomotor activity in aged rats, but the underlying mechanism is unknown. The aim of this study was to determine the effect of CIT administration on locomotor activity and dopamine activity in healthy aged rats. METHODS: Sixty adult (3-mo-old) and aged (20-mo-old) rats were divided into four groups (n = 15 each) stratified by age (adult versus old) and diet (control versus CIT; i.e., Ad-Control, Ad-CIT, Old-Control, Old-CIT) and fed for 4 d on either a CIT-enriched diet (5 g/kg daily; Ad-CIT and Old-CIT) or an isonitrogeneous control diet (Ad-Control and Old-Control)...

Cocaine- and amphetamine-regulated transcript (CART) peptides are widely expressed not only in the brain but also in numerous endocrine/neuroendocrine cells as well as in neurons of the peripheral nervous system. The present study investigated the distribution patterns of CART-like immunoreactivity in the pelvic plexus (PP) of the female pig. The co-expression of CART with principal neurotransmitter markers: choline acetyltransferase (ChAT), tyrosine hydroxylase (TH), serotonin (5-HT) or biologically active neuropeptides: pituitary adenylate cyclase-activating polypeptide (PACAP), substance P (SP), calbindin was analyzed using double immunohistochemical stainings...

In the pathogenesis of atopic dermatitis (AD), skin barrier dysfunction and T-helper (Th) type 2 immune reactions play important roles. Alterations in the stratum spinosum of AD have not been studied in much detail. In this study, we investigated the changes of structural proteins and adhesion molecules residing in the stratum spinosum of AD lesional skin, and whether Th2 cytokines including interleukin (IL)-4 and IL-13 alter the expression of these proteins. Skin samples were collected from patients with AD and from healthy controls...

Activation of naive CD4(+) T cells results in the development of several distinct subsets of effector Th cells, including Th2 cells that play a pivotal role in allergic inflammation and helminthic infections. SWAP-70-like adapter of T cells (SLAT), also known as Def6 or IBP, is a guanine nucleotide exchange factor for small GTPases, which regulates CD4(+) T cell inflammatory responses by controlling Ca(2+)/NFAT signaling. In this study, we have identified a novel alternatively spliced isoform of SLAT, named SLAT2, which lacks the region encoded by exons 2-7 of the Def6 gene...

Both prokineticin receptor 2 (pkr2) and prokineticin 2 (pk2) gene-deficient mice have hypoplasia of the main olfactory bulb (MOB). This hypoplasia has been attributed to disruption of the glomerulus that is caused by loss of afferent projection from olfactory sensory neurons (OSN), and to the impaired migration of granule cells, a type of interneuron. In the present study, we examined whether migration of the second type of interneuron, periglomerular cells (PGC), is dependent on the pkr2 expression by observing the localization of distinct subpopulations of PGC: calretinin (CR)-, calbindin (CB)- and tyrosine hydroxylase (TH)-expressing neurons...

Rivaroxaban is a direct oral anticoagulant that is prescribed for the prevention and treatment of thromboembolisms. Rivaroxaban is cleared renally and a common side effect (1-10%) is renal impairment of unknown pathophysiology. We are the first to describe a case of biopsy-proven acute tubulointerstitial nephritis, most likely caused by rivaroxaban.
