toll-like receptor 4 (tlr4), considered one of  the most important tlr, recognizes lipopolysaccharide of  gram-negative bacteria. recognition  of  ligands by  tlrs  induces signaling pathways resulting in activation of transcriptional factors such as nf-κb which are involved in  the  expression of  inflammatory cytokines and  chemokines. to  prevent  an inappropriate immune response, a complex ...

our prior study found  that transforming growth factor  beta-induced (tgfbi) is  an important negative regulator in tlr-induced inflammation. however, whether tgfbi may affect inflammation during lipopolysaccharide (lps)-induced endotoxin tolerance (et) is still unclear.this study aimed to investigate whether tgfbi was involved in the mechanisms of et in human through dampening nuclear factor-k...

objective: recent studies suggest that intermittent and prolonged normobaric hyperoxia (ho) results in ischemic tolerance to preventing ischemia brain injury. in this research attempts were made to see the changes in excitatory amio-acid transporter 3 (eaat3), tnf-α levels, and nf-κb activity following prolonged and intermittent nbho preconditioning. materials and methods: rats were divided i...

Background: Aging is associated with attenuation of immune responses. Studies show that old people are vulnerable to infectious diseases such as influenza. α-Tocopherol as an immunomodulator affects immune responses. In the present study, the effect of α-tocopherol, on lymphocyte responses i.e. interferon-gamma (IFN-γ), Tumor Necrosis Factor-alpha (TNF-α), and nuclear factor-κB (NF-κB)  in elde...

Type 2 diabetes mellitus (T2DM) is an age‑related disease associated with cerebral inflammation and Alzheimer's disease. Garcinia mangostana pericarp (GMP) possesses antihyperglycemic, antidiabetic anti‑inflammatory effects. The aim of the present study was to evaluate effect GMP extract on in Wistar rats T2DM by examining expression levels glial nuclear factor‑κB (NF‑κB), interleukin ...

The medicinal uses of saffron, the dried stigmas of Crocus sativus L., have very long history in food coloring agent, and flavoring agent as well as traditional medicine for the treatment of several diseases. Crocus sativus is rich in carotenoids that affect immunity. This review summarizes the putative immunoregulatory effects of saffron and its active its derivatives including crocin, croceti...

Objective(s): This study aims to determine the effects of ozone therapy on restoring impaired Nrf2 activation to ameliorate chronic tubulointerstitial injury in rats with adenine-induced CKD. Materials and Methods: Sprague–Dawley rats were fed with 0.75% adenine-containing diet to induce CKD and chronic tubulointerstitial injury. Ozone therapy was administered by rectal insufflation. After 4 we...

Abstract Background Sanziguben polysaccharides (SZP) are large amounts of classical Chinese medicines from (SZGB). Moreover, SZGB is a widely applied compound prescription for diabetic nephropathy (DN) treatment, but the role still unclear. This study initially explores mechanism SZP in treatment DN. Methods The high-fat diet plus streptozotocin injections were used to replicate DN models male ...

Tumour necrosis factor-α (TNFα) is a multifarious mediator of lymphoid tissue growth and antimicrobial defence mechanisms, it acts as pro-inflammatory regulator. The function TNFα in parasite infection the underlying mechanism through which nuclear factor-κB (NF-κB) regulates remain largely unclear teleosts. In present study, ( ToTNF α) from golden pompano Trachinotus ovatus ) was identified, i...
