New prospects of mesenchymal stem cells for ameliorating temporal lobe epilepsy
AbstractTemporal lobe epilepsy (TLE) is present in 30% of epileptic patients and does not respond to conventional treatments. Bone marrow derived mesenchymal stem cells (BMSCs) induce endogenous neural stem cells, inhibit neurodegeneration, and promote brain self-repair mechanisms. The present study addresses the feasibility of BMSCs transplantation against pilocarpine-induced TLE experimentally. BMSCs were injected either intravenously (IV) or in hippocampus bilaterally (IC). Increased cell count of BMSCs was achieved via IC route. BMSCs treatment ameliorated the pilocarpine-induced neurochemical and histological changes,...

Helicobacter pylori LPS-induced gastric mucosal spleen tyrosine kinase (Syk) recruitment to TLR4 and activation occurs with the involvement of protein kinase C δ
AbstractSpleen tyrosine kinase (Syk) has emerged recently as a major effector of proinflammatory genes expression induced by LPS-elicited TLR4 activation, and manifested by the up-amplification in the production of inflammatory mediators, including PGE2 and NO. Here, we investigated the nature of factors involved in the recruitment and interaction of Syk with TLR4 in gastric mucosa in response toH. pylori LPS. We show that stimulation of gastric mucosal cells with the LPS leads to localization of Syk with the membrane-associated TLR4 complex and its activation through phosphorylation on Tyr. Furthermore, we reveal that the...

Molecular signature of nitric oxide on major cancer hallmarks of colorectal carcinoma
AbstractColorectal cancer (CRC) is the one of the most important diseases throughout the world. Several aetiological risk factors, viz. sedentary life style, smoking, alcohol intake, less physical activity, red meat, and microbiota, are associated with the development of CRC. Molecular pathophysiology of CRC implies inflammation, metastasis, apotosis and angiogenesis. Inflammation involves interaction between various immune cells, inflammatory cells, chemokines, cytokines, and pro-inflammatory mediators, such as cyclooxygenase (COX) and lipoxygenase (LOX) pathways, which may lead to signalling towards, tumour cell prolifer...

As a painkiller: a review of pre- and postnatal non-steroidal anti-inflammatory drug exposure effects on the nervous systems
AbstractDiclofenac sodium (DS) is commonly used for the treatment of acute and chronic pain, even for extended periods of time. Over the years, DS has been associated with toxicity in nervous tissue, in addition to its anti-inflammatory properties. Basic neurobiological research has enhanced our understanding of the biological and pathological outcomes of toxicity. Several studies have suggested DS-induced cytotoxicity in the nervous system. Prenatal toxicities of DS are thought to be capable of leading to postnatal defects. This review describes the morphoquantitative, histological and pathological effects of DS on the ce...

Attenuation of nociceptive pain and inflammatory disorders by total steroid and terpenoid fraction of Euphorbia tirucalli Linn root in experimental in vitro and in vivo model
AbstractThe plantEuphorbia tirucalli Linn has been successfully used as a tribal folk medicine in India and Africa for the management of acute inflammatory, arthritic, nociceptive pain and asthmatic symptoms. The present study was conducted to assess the anti-inflammatory, analgesic, anti-asthmatic and anti-arthritic role of the total steroid and terpenoid rich fractions of the hydro-alcoholic extract ofE.tirucalli root (STF-HAETR). STF-HAETR fraction demonstrated 71.25  ± 2.5 and 74.25 ± 5.1% protection against acetic acid-induced pain and central neuropathic pain at 75 and 100 mg/kg...

Targeting of circulating Th17 cells by β-D-mannuronic acid (M2000) as a novel medication in patients with rheumatoid arthritis
This study aimed at investigating the inhibitory effect of β-D-mannuronic acid (M2000) on the Th17 circulating levels and IL-17 a related cytokine in rheumatoid arthritis (RA) patients.MethodsThe study included 27 patients with RA who had failed response to treatment. All patients were treated orally by M2000 at a dose of 500  mg twice daily for 12 weeks (Clinical trial identifier: IRCT2014011213739N2). The patients based on anti-tumor necrosis factor alpha (TNFα) blocker treatment were classified into two groups (conventional group and etanercept group). They were then allowed to continue their treatm...

Mesenchymal stromal cells modulate gut inflammation in experimental colitis
In this study, we explored the immunomodulatory potential of ADMSC in a classical model of DSS-induced coli tis. First, we found that treatment of mice with ADMSC ameliorated the severity of DSS-induced colitis, reducing colitis pathological score and preventing colon shortening. Moreover, a prominent reduction of pro-inflammatory cytokines levels (i.e., IFN-γ, TNF-α, IL-6 and MCP-1) was observed in the colon of animals treated with ADMSC. We also observed a significant reduction in the frequencies of macrophages (F4/80+CD11b+) and dendritic cells (CD11c+CD103+) in the intestinal lamina propria of ADMSC-treated...

Effects of glutamine, taurine and their association on inflammatory pathway markers in macrophages
AbstractThe immune system is essential for the control and elimination of infections, and macrophages are cells that act as important players in orchestrating the various parts of the inflammatory/immune response. Amino acids play important role in mediating functionality of the inflammatory response, especially mediating macrophages functions and cytokines production. We investigated the influence of glutamine, taurine and their association on the modulation of inflammatory pathway markers in macrophages. The RAW 264.7 macrophage cell line was cultivated in the presence of glutamine and taurine and proliferation rates, ce...

Curcumin affords neuroprotection and inhibits α-synuclein aggregation in lipopolysaccharide-induced Parkinson’s disease model
AbstractParkinson ’s disease (PD) pathology is characterized by the abnormal accumulation and aggregation of the pre-synaptic protein α-synuclein in the dopaminergic neurons as Lewy bodies (LBs). Curcumin, which plays a neuroprotective role in various animal models of PD, was found to directly modulate the aggrega tion of α-synuclein in in vitro as well as in in vivo studies. While curcumin has been shown to exhibit strong anti-oxidant and anti-inflammatory properties, there are a number of other possible mechanisms by which curcumin may alter α-synuclein aggregation which still remains obscure. The...
