BACKGROUND Inhibition of chemokine receptor 5 (CCR5), a chemokine receptor expressed on activated T cells, is an effective antiviral therapy in patients with HIV infection, but its efficacy in modulating inflammation and immunity is only just beginning to be investigated. In this study we examined the inhibition of CCR5 in combination with the treatment(More)
In order to study the effects of ethyl pyruvate on cardiomyocyte apoptosis following ischemia/reperfusion (I/R) in vitro and the expression of Bcl-2 and Bax proteins, isolated rat hearts were perfused in a Langendorff model. Twenty-four rats were randomly divided into 3 groups (n=8 in each group): control group was perfused for 120 min. In the I/R group,(More)
The present study used an in vitro model of cold cardioplegia in isolated working rat hearts to evaluate the possible role of ethyl pyruvate (EP) in promoting cardiac function and preventing apoptosis. Two groups of rats were evaluated; the EP (2 mM EP; n=8) and control (n=8) groups. Isolated rat hearts were perfused with Krebs-Henseleit buffer (KHB) for 30(More)
OBJECTIVE T helper 17 cells and interleukin-17A have been implicated in the progression of abdominal aortic aneurysm (AAA). Retinoic acid-related orphan receptor gamma thymus, the master transcription factor of T helper 17 cell differentiation, is selectively antagonized by digoxin. However, the effect of antagonizing retinoic acid-related orphan receptor(More)
BACKGROUND Interleukin (IL)-12 and -23 share the p40 subunit and are crucial for the development of T helper (Th) 1- and Th17-cell responses in acute graft rejection. However, little is known about the impact of treatment with antagonistic anti-p40 antibody in inhibiting rejection of cardiac allografts. METHODS C57BL/6 mice were transplanted with(More)
The effects of stromal-derived factor 1 preconditioning (PC) on apoptosis of bone mesenchymal stem cells (BMSCs) treated with hypoxia plus serum deprivation were investigated. Bone mesenchymal stem cells were cultured with the whole marrow-adherence technique. RT-PCR and immunohistochemistry were used to detect the expression of CXCR4. BMSCs were incubated(More)
Candida albicans is a common opportunistic fungal pathogen, causing both superficial candidiasis and life-threatening systemic infections in immune-compromised individuals. Calcium signaling is responsible for this pathogen in responding to several stresses, such as antifungal drugs, alkaline pH and membrane-perturbing agents. Our recent study revealed that(More)
The effects of oxidized low density lipoprotein (ox-LDL) on the proliferation of cultured human vascular smooth muscle cells (vSMC) were investigated in vitro. By using NaBr density gradient centrifugation, LDL was isolated and purified from human plasma. Ox-LDL was produced from LDL by being incubated with CuSO(4). ox-LDL was then added to the culture(More)
Maraviroc (MVC), a specific antagonist of CCR5 expressed on macrophages and activated T cells, may modulate inflammation and may be useful in patients with HIV infection. In this study we used nonhuman primates to examine the effect and mechanism of MVC alone or in combination with cyclosporine (CsA) to prolong cardiac allograft survivals. In an established(More)
